7 Reasons Why Car Sputters When Starting?

So, your car is sputtering when you start it. Well, you are in the right place. In this article, we will look at all the possible reasons why a car might sputter when starting it and the solutions for them.

There is a whole lot of potential reasons why your car might be sputtering when you first start it, but after reading this article, you will know how to troubleshoot it and also know what to do to fix the problem.

Read on to learn more about why your car might sputter when you start it.

Car sputters when starting?


There are all kinds of reasons why a car might sputter when you start it and then be fine after it gets going. Before going into detail about the reasons we will list them out for you, so if you think a particular problem causes yours, then you can start their first.

The main reasons why a car might sputter when you start it are:

  • Weak Battery
  • Bad or Dirt Spark Plugs or Fuel Injectors
  • Bad or Dirty Sensor and Clogged Air Filter
  • Bad Fuel Pump
  • Exhaust Leak or Leaking Gaskets
  • Failing Catalytic Converter
  • Malfunction Ignition Switch

These are the main problems, and we will look at each one in-depth below.

1. Weak Battery

The first problem could be that you have a weak battery. If the battery is just charged enough to turn the car over, then the engine might sputter at first before it gets going.

Once the engine is running, then it doesn’t require as much power from the battery, and that is why it might even out. Also, once the engine is running, it starts to charge the battery with the alternator.

If the sputtering was from a weak battery, then it will probably only happen once, because after driving the battery will get charged. If the battery is not holding a charge though, then it could keep causing the car to sputter when you start it.

To see if the battery is weak turn on your headlights before starting the car and if they are dim, then the battery is weak. Try charging it or testing the battery to see if you need a new one. Replacing the battery will fix the sputtering if that is the problem.

2. Bad or Dirt Spark Plugs or Fuel Injectors

The next thing that could cause your car to sputter when starting is bad or dirty spark plugs. This is because it takes a spark to ignite the fuel to get the engine going and if the spark plugs are dirty, then it may not be giving enough of a spark causing a rough start.

As the engine is going, it may not be as easy to notice the sputtering from all the other engine noise. You can change or clean your spark plugs if you think that is what is causing the sputtering and if it is, then the sputtering will stop after doing that.

The fuel injectors could also be dirty which could lead to not enough fuel being squirted into the cylinder. Cleaning them is also a good idea if you think the issue is happening when the fuel is being ignited.

3. Bad or Dirty Sensors and Clogged Air Filter

All kinds of sensors are also involved when starting the car. You have the oxygen sensor, the mass airflow sensor, and the fuel injection sensor.

If any of these are dirty or going bad, then you will not get a proper mixture of gas in the cylinder when going to start the car. This will lead to the sputtering when you start it.

Clean all the sensors and make sure that they are not the problem. If the problem continues after cleaning or replacing them, then it was something else. Tied into the dirty sensors is a clogged air filter.

If the air filter is overly dirty and the proper amount of air can’t pass thru, then it will lead to sputtering issues. Replace the air filter or clean it to make sure that enough air is getting thru.

4. Bad Fuel Pump

The next thing could be that you have a failing fuel pump. The fuel pump is what moves the gas from the tank to the cylinders. If it is getting weak, then it might not be moving the proper amount of gas thru.

Also, if it is the fuel pump, then you may have sputtering when your gas is low, but not when it is full. One way to see if it is the fuel pump is to spray propellant into the cylinder as you go to start the car.

If it starts fine with that, then you can bet that it is the fuel pump going out and needing to be replaced.

5. Exhaust Leak or Leaking Gaskets

The next thing that can cause a sputtering is an exhaust leak. The exhaust leak can be anywhere. It can be at the manifold or farther along under the car.

Exhaust leaks are noisy and also dangerous as the exhaust is hot and can melt surrounding plastics or come into the vehicle. Leaking gaskets on the engine can also cause sputtering because it can affect the fuel mixture.

Exhaust leaks can be found by hooking up a blower into the tailpipe and then spraying the exhaust down with water. Anywhere that bubbles there is a leak and it needs to be fixed.

6. Failing Catalytic Converter

Another part of the exhaust process is the catalytic converter, and if you have one that is failing, then it can cause the engine to sputter.

That is because clean gasses are not countering the gasses that the engine is putting off and some might be going back into the engine causing it not to run smoothly.

If your catalytic converter is going out, toxic gases may also be going into the cabin of the vehicle. It is a good idea to have the catalytic converter replaced if it is failing.

7. Malfunction Ignition Switch

The last potential thing we will look at is a bad ignition switch. If the switch is not working right then, it might not be sending the right signal to the engine to turn it over all the way.

This can lead to sputtering when you go to start it because the proper amount of charge isn’t being applied. This is one of the last things to check though because if it is the ignition switch, then most likely the car won’t start at all.

How do you know?

So, with all these possible causes for a car sputtering when starting, how do you know where to start with fixing the problem? Well, most of these issues will cause a check engine light to come on.

If your check engine light is on, then you should use an OBDII scanner and read the code. You can then look up what the code means and start with fixing whatever problem is being given.

The only think on here that probably won’t send code is a weak battery so if you don’t have a code, then start with the battery first. Everything else will cause a code, and then you will know what to fix from there.


A sputtering car on start can be annoying because there are so many things that could be wrong with the car. Luckily most of the fixes are affordable ones and won’t cause you to have to get a new car.

Just check the engine code and see what the problem is and then replace or clean the bad part. A vehicle that sputters when starting is a pretty simple problem to fix and while annoying it won’t cause you to have to miss work.

Just be sure to deal with it as soon as you can because a sputtering car is losing gas mileage and could be putting toxic gasses into your vehicle. Luckily now you know everything you need to know when it comes to your car sputtering when starting it.

What Are The Different Types Of Charging?

When it comes to charging something, mainly a battery, there are a variety of type/method that can be used. Each type has its positives and negatives. In this article, we will discuss the common basic charging types.

Read on to learn the different charging types that are possible as well as what sets them apart. We will give details so you understand what is going on with each type and also when or why you might want to use a particular type.

Types Of Charging

What are the different types of charging?

Types Of Charging

Before going into deep detail, we will list out the nine basic charging types. Each one has a purpose, and if you want to learn about a particular one, then you can jump straight to it. The main charging types are:

  • Constant Voltage
  • Constant Current
  • Taper Current
  • Pulse Charge
  • Burp Charging
  • IUI Charging
  • Trickle Charge
  • Float Charge
  • Random Charge

Constant Voltage

The first type of charging a battery we will look at is a constant voltage. A constant voltage does what the name implies and provides a constant voltage to the battery.

These types of chargers are generally cheap and simple. In the simplest form, a constant voltage charger can be a DC (direct current) power supply with a step-down transformer that rectifies the power.

You can use this type of charger for both lead-acid cells as well as lithium-ion cells. However, the lithium-ion charger is normally a bit more advanced for the safety of you and the battery. The reason why these are good is that they are cost-effective, but there are better options.

Constant Current

The next type of charging is a constant current. This is similar to constant voltage because it keeps one aspect of the charging constant, but this time it is the current or flow of electricity thru the battery at the constant.

The way it does this is that it changes the voltage, so the current coming out is always equal. When the battery gets fully charged it is able to stop charging.

Most of the time this type of charging is used for nickel-metal hybrid cells and nickel-cadmium batteries. The reason this type of charger is good is that it stops charging when the battery is full, but other types can also do this and work better for certain types of batteries.

Taper Current

The next type of charging is taper current. This type can damage batteries very easily. You can get away with it with some SLA batteries, but it is a good idea to keep an eye on the charging of your battery.

This is because the taper current does not provide a constant voltage. It is a crude type that sends in a voltage that causes the current to diminish as the cell voltage builds up.

The voltage going into the battery is unregulated. This charging should not be used except for the last resort because there are better and safer options.

Pulse Charge

The next type is a very good type to help extend your battery life, and that is pulse charging. As the name suggests, the energy goes into the battery in pulses.

The current goes in as a pulse, and you can set how long of pulse period you want. Normally it is around 1 second. Then, you have 20 milliseconds to 30 milliseconds of rest between pulses.

This resting period allows the battery to stabilize. By stabilizing it means that the battery is able to equalize the reaction across most of the electrodes before the next charge pulse comes in.

By being allowed to stabilize it allows the chemical reaction to keep pace with the incoming charge. This prevents unwanted chemical reactions at the electrode surface such as gas being formed.

It also prevents the formation of crystals and passivation. This type is good for any battery.

Burp Charging

The next type of charging is burp charging which expands on pulse charging. It is just like pulse charging, but with an added step. Before the next pulse goes in, with burp charging it sends a discharge pulse in.

This depolarizes the cells and helps to eliminate any gas bubbles that have built up. The releasing of the gas bubbles is known as burping. Other names for this type of charging are reflex or negative pulse charging.

This type of charging is supposed to extend battery life more and allow for faster charging, but there is no conclusive evidence of this. The only evidence is that burp charging can’t hurt a battery, so it doesn’t hurt to try it if you are a fan of pulse charging.

IUI Charging

The next kind of charging is a newer type for lead-acid batteries, and that is IUI charging. This type is not for all lead-acid batteries, so you want to make sure yours is compatible.

IUI charging is done in stages, and the first stage is bulk charging where it is charged at a constant rate until it reaches a preset point where gases start to form.

When it reaches this point the charger switches into a middle phase that provides a constant voltage and the current drawn by the battery will slowly drop until it reaches a particular point and the current drops at a diminishing rate.

Once it reaches this second preset point the battery switches back to a constant current mode and charges the battery to a higher preset point until it reaches that and then the charger shuts off completely.

This final charge helps stabilize the battery and makes sure that the cells are equally charged ensuring longer battery life.

Trickle Charge

The next type, trickle charging, is designed for battery maintenance. This type is not for bringing a battery back from being dead but is instead designed to keep a battery that is not in use charged.

With trickle charging a small current is applied to the battery at the rate that the battery is discharging. This keeps it charged and ready to go and helps keep chemicals from building up on the inside of the battery hurting its life.

Some charges automatically switch to a trickle charge mode when a battery is fully charged. You can’t use this charging on all batteries though. You shouldn’t use it on NiMH or lithium because they are easily overcharged.

Float Charge

The next type is similar to trickle charge in that it does not overcharge the battery. Float charging is mainly used on lead-acid batteries, and it holds the voltage of the battery at a point that is below the maximum charge.

It is for emergencies mainly and is good for battery backup. The way it works is the battery and load are permanently connected in parallel across the DC charging source.

Random Charge

The last type is a random charge. This is when a random charge is applied to something. This is because the power is coming from a source that can’t be controlled completely.

For example, the alternator works based on how fast the engine is going, so it provides a different charge at different times. Another instance is solar power where the sun is at different levels at different times.

The random charge is pretty common but generally isn’t used for charging batteries in most cases.

The best battery tender also help you recharge and maintain battery by the great way. You should read about it.


So, now you know all the basic types for charging a battery. You know the nine common battery charging types and how they work.

You also now know the benefits and negatives of each one. Whenever you need to charge a battery, you should be able to pick out the best battery charging type for your needs.

Car Battery Average Life and How To Extend It?

There are a few different kinds of car batteries on the market today, but they all work in the same way. All car batteries are 12-volt, and they are arranged in cells that are around 2-volts each. The six cells are made up of plates and acid.

This is how they store and transfer power. Due to the way they are made they won’t last forever because natural breakdown occurs in them. Read on to find out the average life of a car battery and also learn ways to extend the life of the battery.

Car Battery Average Life

Car battery average life and how to extend it?

Car Battery Life Expectancy

On average a car battery will last two to five years, but most last around four years. Sometimes a battery might be near the end of its useful life but still give you a little longer.

Also, if you take care of your battery and try to limit things that put a strain on the battery it will help it live longer. One other way to get more life out of the battery is to buy a better one to start with. Cheaper batteries are cheaper for a reason, and the plates that are used inside aren’t as good as on more expensive batteries.

The easiest way to keep you batteries alive is recharge it, the best battery tender is wonderful tool to do that. You should buy it.

Why does battery break down?

So now that you know the average life of a car battery we can look into why a battery stops working over time. Well, from the first time you start your car with a new battery build up begins to occur on the plates.

This sulfuric acid buildup causes the electrons in the battery to stick to the plate and not move thru the battery. The build-up on the plate also deteriorates them.

This break down of the plates causes them not to transfer energy as well. Over time this buildup becomes too much, and the damage to the plates becomes too much, and the battery stops working.

Reversing buildup

When charging the battery, you are reversing this buildup of the sulfuric acid on the plates. This is because the charger puts a small vibration into the battery and it breaks the crust off the plates.

By breaking this crust off it not only restores the electrons back into the acid and water solution that is inside the battery, but it also slows down the breakdown of the plates.

That is why it is so important to keep a battery charged. If you keep a battery charged it would help the plates last longer and in turn will allow the battery to last longer.

Other factors that affect battery life.

Outside of keeping the battery charged there are a few other things that can reduce the life of a battery. One of those is similar to the charging aspect, and that is letting a battery sit for long periods without being used.

Long periods of sitting allows the sulfuric acid to build upon the plates and this causes it to break down. Also, when the electrons aren’t moving, they kind of settlement to the bottom or get stuck in the buildup and stop wanting to move.

When you drive a car, the alternator charges it helping keep the electrons active, but if the battery sits the buildup on the plates get too much, and the electrons become sluggish.

Other factors that affect battery life

Other factors that affect battery life

Driving the car on short trips though may do more harm to the battery then good though when it comes to the life of the battery. This is because it takes a lot of energy to get the car started and if you don’t drive long enough to recharge the battery, then the battery will get weaker and weaker with every start.

Also, short trips will lead to more sulfuric acid crust on the plates, and if you don’t drive the vehicle long, then that crust will not have a chance to get broken off. Also, the solution will break into two parts.

A light part and a heavy part. The heavy part will have to do all the work to keep the car going because the light part won’t have any electrons. This puts a strain on your battery.

Temperature is another major factor in how long a battery will last. Warm temperatures will cause the buildup on the plates to occur faster. This is because heat accelerates the chemical reaction.

The opposite happens if you live in a cold place. Since it is colder, the chemical reaction of crust forming on the plates will be slower, but if cold areas the solution is more likely to separate like was mentioned in the previous part.

That is why for longest battery life it is best to live in an area with moderate and consistent temperatures. Extreme temperature changes can be hard for the battery to deal with.

However, the temperature is partially out of your control, but it is just something you have to deal with and remember when choosing a place to live.

The last thing that can shorten battery life is by not having a battery that is properly secured or driving on bumpy roads. If the battery is not secured tightly, then shifting can cause the plates to get damaged.

This is especially possible if you drive on a lot of bumpy roads. Bumps can cause the battery to jar, and this can damage the plates inside. Also, vibration over time of the battery can lead to damage inside. Especially as the plates corrode, they will become brittle, and the vibration can break them ending the life of the battery.

Prolong Life


So now that you know some of the cases of shortening a car batteries life we can look at ways to increase the life of the battery. The first is pretty simple, and that is use accessories less.

Having chargers plugged in, and other things will drain the battery faster. If the battery gets drain more than it is being charged while driving, then the life will be affected.

Also, limit the use of the radio and things when dealing because the battery isn’t being charged then, and the extra draw puts a strain on the battery.

Lastly, related to this tip is make sure all the lights are off when you leave the vehicle. If they are not, then the battery will die completely and need jumped and recharged. This will shorten the life of a battery, especially if it occurs regularly.

Talking about charging the next thing to do to keep a battery lasting is charge it regularly and make sure it stays fully charged. This has already been mentioned, but the part that hasn’t been mentioned is having the battery tested consistently.

By testing the battery, you can make sure it is getting charged all the way and also see how effective it is running. This will help let you know when your battery is nearing the end of its life. You can use a battery tester or an best automotive multimeter to test the battery.

Regulating the battery temperature is another way to help it last longer. You can get a sleeve to put around the battery. This sleeve helps keep the battery warm in colder times and then helps keep it cool in the warmer times.

It does this by providing insulation, but also a shield from heat. The cover goes around the battery, kind of like a sock, and it helps it last longer.

The last thing you can do to keep a battery running longer is to clean the battery regularly. If you see corrosion forming on the nodes, then clean it off.

Also, some batteries need water added to them, so it is important to do that regularly to keep the battery running right. The last thing to do when cleaning the battery and checking it is to make sure that it is tightened down all the way to prevent shifting and damage that comes from that while driving.


So, after reading this, you now know that an average life expectancy of a car battery is two to five years with most lasting around four. You also know things that reduce the life of the battery so you can minimize those things and you know the things you can do to help keep your battery working longer. Using the tips here you should be able to get the most life possible out of your car battery.

Car Shakes When Driving Slow?

When driving your car should go straight and smoothly. This means that in theory on a straight road you should be able to let go of the wheel and your car will stay straight.

This doesn’t always work in practice because the road is not smooth and has bumps that will cause the vehicle to turn off, but the vehicle should not shack while driving.

A lot of different things can be the case with your vehicle shaking while driving. Keep reading to learn some of the things that could cause your car to shake at low speeds and some solutions for the issues.

Car shakes when driving slow?


Before going into in-depth detail about each thing we will provide a list of the possible issues, so if you have an idea of what might be wrong, you can jump to that section first.

Some of the main things that can cause your car to shake at low speeds are:

  • Tire Issues
  • Brake Issues
  • Engine Mount Issues
  • Bearing Issues
  • Axel Problems
  • Steering Component Issues

Depending on what the problem is it can be an easy thing to fix, or it can be more in-depth. Now we will look deeper into each potential problem and explain how to diagnose it and provide a solution for it.

Tire Issues

The tires are the first thing to consider when trying to figure out why your car is shaking at low speeds. There are a few different things that could be wrong with the tires, but each is a pretty simple solution.

The first thing when trying to figure out if the tires are the cause of the shake is to examine the tires. You want first to make sure they have a good amount of treed on them.

If the tires are wearing out and loosing treed, then they may not be gripping the road good which can cause shake.

The next thing when looking at the treed is to make sure the wear is even. If the wear is not even, then this can be an indication of the tires needing balanced or aligned.

The treed not being wore even can also be a sign of some other issues, but it is best to start with having the tires balanced and aligned to see if that fixes the problem.

To know if the treed is not wearing evenly you can look for flat spots on one part of the tire and not the others. Also, cupping can occur where one part of the treed is lower then the other making it appear like a bowl.

To have the tire balanced, you will need to take it to a shop so they can put it on a machine and make sure the weight is distributed right. Balancing the tires keeps them from wobbling.

The wobble can cause the car to shake. When having the tires balanced, you should also have them aligned. Making sure the tires are correctly aligned will help keep the car in the straight path that was mentioned early.

Since the car won’t pull, it will not shake, and the tires will wear evenly. If the tires are too unevenly wore compared to the others, then you might have to get a new set to fix the shaking problem entirely or with time after rotating, balancing, and aligning the tires might wear themselves back to an even pattern.


The next thing to consider when you have a car that shakes at lower speeds is the brake system. This is especially true if the wobbling or shaking happens while braking.

A few different things can go wrong with the brakes that can cause the car to shake. The main thing that can lead to shaking is a brake rotor that is out of round.

If the brake rotor wears unevenly from the car not being balanced or aligns right, then it can lead to high points on the rotor. These high points can rub against the calipers and cause the car to shake.

If the tires seem to find or you have had them balanced and aligned, but still have shaking, then the next thing you should have looked at is the brakes.

At a shop, they can remove the rotors and make sure that they are round and even. If they are not, then they might be able to resurface them, if there is enough metal left.

Rotors can only be resurfaced so much thought before they need to be replaced because they have to stay a certain thickness to work right.

Another part of the brake system that can cause shaking is a sticking brake caliper. The caliper is what closes the brake pads onto the rotor.

If the caliper stays shut, then the pads will be rubbing the rotor as you try to accelerate. This will cause shaking, and it will get worse as you pick up speed.

If you think the caliper is sticking, then you need to get it checked out because it is dangerous and can damage the rotor.

Engine Mount Issues

The next thing that can cause a car to shake at low speeds doesn’t have to do with the wheels or driving system at all. It instead has to do with how the engine is held into the vehicle.

The engine is held in with metal mounts, and there is also rubber parts under the hood too to help hold the motor in. If these mounts come loose or the rubber breaks down, then the engine can shake as you drive.

A lot of power is inside the engine and the force being created the engine can cause the car to shake if the mounts are bad.

If the brakes and tires seem okay, then the next thing you should check is the mounts. If the engine appears loose, then the mounts will need to be replaced or retightened.

Bearing Issues

Moving on we are going back to the wheel area for the next issues, and that is bearing issues. The bearings are what helps the wheels spin freely and lubricate them.

Sometimes the bearings go and though and this leads to friction and rub around the wheels. The issues will be noticeable at lower speeds and may get better as you speed up. Also, the problem may be felt more when turning if it is the bearings.


Another thing that can cause the problem to be worse in one position over another is axel issues. The axel issues could be CV joints or different joints breaking down.

The joints are what connects the axel to the wheels, and if they break down, then there might be rubbing happening in one wheel position and not another.

This can cause shaking and most likely can be noticeable at low speeds and turning, mainly depending on which joint is bad. One way to see if it is a bad join is to jack the car off the ground a little and see if the wheel has play.

If the wheel moves when pushed on from the side, then you have a bad joint that needs to be fixed. Pushing on the wheel should not be able to move it with good joints.

Another thing that could be wrong with the axel that could cause shaking is a bent axle. If the axle is bent, then it will not spin round as the car rolls. Instead, it will have a point where it causes a bump in the rotation.

At slow speeds, this bump may seem like the road, but as you get faster, the bump will cause shaking. If the car has been wrecked, especially recently, then you will want to make sure there is no damage to the frame or axel. A bent axel is significant damage and could lead the car to be considered totaled.

Steering Components

The last thing that could lead the car to shake at slow speeds is the steering components going bad. Maybe the car isn’t shaking at all, and just the steering wheel is loose, and it seems like the car is shaking.

Also, the steering column might be worn out, and this would make it seem like the car was shaking. If you have checked everything else that we have mentioned up to this point, then it is time to check the steering system itself and see if the problem lies in it.


A lot of different things can lead to a car shaking at slow speeds, and it is essential to have them checked out as soon as possible. The steering wheel is your connection to the car and the road, and it is the first sign of problems.

If you have shaking, then you need to get it fixed before other things go bad. The first place is to start with the tires and see if they need balanced or aligned.

The next thing to check is the breaks, and this could even be the first thing if the issues are mainly noticeable when breaking.

After you have tested those things, if you still have shaking, then is time to go deeper and check the engine mounts, wheel bearings, and different joints.

If none of these are the problem or the car has been wrecked recently, then check the axel.

Lastly, if all else fails to check the steering system itself because the problem may be a loose wheel that is causing you to think the car is shaking but it might not be. Now you have a checklist of things to check when your vehicle is shaking though and a good idea what to do about them.

Car Still Won’t Start After Replacing Battery?

A dead or bad battery is a common reason why a car will not start. A car uses the power from the battery to engage the starter to get the car’s engine to turn over. This takes a lot of power, and a weak or bad battery is not capable of doing this.

A lot of times you can use another car and jump the battery to help get it going to get to a place to have the battery replaced, but what if your car still won’t start after having the battery replaced.

Well, to find the answer to this question keep reading and we will go in-depth to the different reason why the car still might not be starting and some solutions for them.

Replaced Battery Car Won't Start

A lot of times to figure out what is wrong with a car that won’t start, a lot depends on the sound that the car makes while you try to start it. If it makes a K-K-K-K type sound, then chance are the battery is bad or not connected right.

The first thing to check after replacing a battery and the car still not starting is the battery wires. It is more common then you may think that the battery did not get connected right.

The leads could have come loose or not be making good contact. Check them again after replacing the battery and see if they are in fact tightly connected.

The next thing could be that you replaced it with the wrong type of battery or a battery that is not strong enough. If the new battery doesn’t have enough cold cranking amps, then this can prevent it from starting the car.

Recheck the new battery and make sure that it is at least equal in strength to the old battery that you had. If it is, then you can move on to the next stage.


The other thing that could lead to the K-K-K-K sound is a dead battery. The battery may be new, but if you have been driving the car, then it might have got drained, and if the alternator is bad, then it won’t have been getting recharged.

The alternator not working normally triggers lights on your dash, so if you see lights come on, especially the battery one look in the manual and see what they mean.

If you have an alternator that is failing, then it doesn’t matter how new the battery is because it won’t be getting charged as you drive and therefore won’t be able to start the car.


If the sound you get is a Grr-Grr-Grr type noise, then chance are it is not the battery that is the problem causer at all. A growling Grr sound when trying to start the car is an indication that the starter is bad.

If the start is bad, then it will need to be replaced. There are also a few other sounds that come with a bad starter.

The first is no sound at all. If when you turn the key, no sound is made, then it might be a bad starter, but could be a few other things that we will get to later. If you have no sound though, then you can have the starter tested to see if it is bad.

Lastly, if you hear a grinding, clashing, or banging sound while trying to start the car, then it could be an indicator that some of the teeth on the starter are broke. A

sound that sounds like shifting with a bad clutch could mean that the starters drive gear might be damaged, or the flywheel on the vehicle may have damaged teeth.

If you have any clashing, knocking, or metal scraping sounds when trying to start the car, then you need to have it checked out to make sure more damage does not occur.

Reasons why cars can not start

There are many reasons why cars can not start

Fuel Pump

Another problem when the vehicle doesn’t make a sound when you try to start it could be a bad fuel pump or fuel pump relay. When you turn the key to the on position, you should be able to hear a soft whine of the fuel pump intake turning on.

If you don’t, then the fuel pump motor might be weak or dead. If the fuel pump is just weak, you might be able to tape on the fuel tank near where the pump is at to get the motor going, but this won’t always work if it is to die.

A dead fuel pump will need to be replaced but check the relay first to make sure it wasn’t just a blown a fuse.

Also, make sure you have enough gas in the car for it to be able to start. Sometimes you don’t have enough gas for the fuel pump to suck it up. This can especially happen when parked on an upward slope.

The gas might be in the back of the tank and not going into the fuel pump. One last problem that the fuel system might be having that prevents the car from starting is frozen lines.

If it is cold and water got into the gas system, then the lines can freeze, and this can prevent the fuel from getting to the engine and being able to start.

Bad Spark Plugs

Talking about the fuel, the problem could also be that it isn’t igniting properly. If you have old spark plugs, then they may not be firing a good enough spark to get the engine to turn over.

Spark plugs usually last for 100,000 miles, so it can be easy to forget to replace them. Check them if the engine is not turning over and making a misfiring type sound.

Also, bad spark plugs will cause the engine not to run smoothly, so before you get to the point where the car won’t start, if you notice rough idling or riding, then check the spark plugs and make sure they are still good.

Security System

The last possibility of why a car with a new battery might not start is that the security system got engaged. If the steering wheel will not turn, then the anti-theft system got tripped.

To get the wheel to unlock you need to nudge it some. This will help loosen it from the locking pawl and will allow the car to start.

Another security feature that may keep your car from starting is if it has a proximity key. Make sure the key is in the car or on your person or else the car won’t start. If you are rushed, then you might have forgotten it in the house or left it in your pants or jacket from the night before.

Before freaking out, make sure you have it on you because the problem might be as simple as just not having the proximity key in the car with you.



There is a lot of reason why car still won’t start after replacing battery. The critical thing is to stay calm and work your way thru the problem.

First, make sure the new battery is connected right and is the right one. Then, if your car has a proximity key, make sure it is with you. Next, listen to the sound the car makes when you try to start it.

If it is a K-K-K-K sound, then the battery is weak or not connected. If it is a Grr sound, then it is most likely a bad starter. Clashing sounds can also be the starter or flywheel.

If no sounds happen, then it could be the starter or the fuel pump not working. Depending on the sounds you get, you can have an idea of where to start for checking things so you can get your car running again quickly and without spending too much more money.

What Voltage To Charge An AGM Battery?

Over time and use batteries go dead and then they need to be charged. The longer a battery sits without being used, the more it will drain. This is especially true in extreme temperature areas.

Even AGM batteries, which are top quality, will need to be charged at some point. When it comes time to charge an AGM battery, what voltage should you use?

Well, after reading this you will know and then be able to choose the right charger for your battery and charging situation.

What voltage to charge an AGM battery

What voltage to charge an AGM battery?

AGM Battery Overview

Before getting into voltage we will give a fast break down of what happens in the battery when it needs to be charged. In an AGM battery, you have absorbed glass matts, and they hold the electrolyte mixture that holds the charge.

You also have metal plates. As time passes the sulfur in the electrolyte sticks and builds up onto these metal plates. When this happens, the electrons are trapped and can’t move thru the battery. That is why it has a low charge.

What A Charger Does?

A charger sends pulses into the battery, and these pulses help break the sulfur build up off the plates. The sulfur is restored into the electrolyte which is held on the glass matts in an AGM battery, and this restores the charge to the battery.

As the battery ages though some of the sulfur is lost or stuck permanently to the matts and this is why batteries eventually go bad.

What Voltage To Use?

So, now that you understand the basics of how charging works, what voltage should you use? Well, picking the right voltage is pretty easy.

Voltage is the amount of energy that is going into the battery, and you want the voltage to be equal to the voltage of the battery when choosing a charger.

This means if you have a 12-volt battery, then you would want to get a best 12v battery charger. It is that simple when it comes to the voltage of making sure that the voltage matches the voltage of the battery.

Some chargers have switches, and you can change the voltage that is being put of by the charger. These are nice, especially if you have multiple batteries of different voltages around.

That way you can use the same charger for all your batteries. Just make sure you change it to the right voltage setting when switching your batteries out.

battery tender

If you have a 12-volt battery, then you would want to get a 12-volt charger


What Amps?

If figuring out the voltage to use is as simple as matching it to the voltage of the battery, then what makes charging an AGM battery different from others? Well, we have an article available for you about that, but the key part is to use lower Amps with an AGM battery.

For the full explanation of why you can read the other article, but amps is the speed at which the current is being applied to the battery.

To prevent heat and to overcharge it is better to apply the charge slower with AGM batteries. This has to do with how they are made.

In the other article, we also cover if it is necessary to use an AGM charger or if a standard battery charger will work with AGM batteries.

How Often To Charge.

AGM batteries don’t need to be charged as much as other batteries, but they do still need to be charged. You should test them, and once they start getting down to 10,5 volts or so, you should load them.

You should keep your battery on a maintainer when it is not being used for long periods and this will help it not lose its charge and will help the battery last longer.


AGM batteries do still need to be charged like other batteries, but they hold their charge better so don’t need to be charged as often. When loading an AGM battery, it is important to remember to use a charger with lower amps.

For the voltage of the charger to use it is simple to figure out. When charging any better, you want to make sure the energy of the charger matches the voltage of the battery.

That is not just true for AGM batteries but is a rule for all batteries. The voltage is how much power is being put out, and amps are the speed at which it is being put out.

To charge a battery properly, the voltage needs to be the same as the battery being charged. If it is less than the battery being charged, then it won’t charge all the way, and if it is more, then it will damage the battery.

It is that simple to make sure the two voltages match when determining what voltage to charge your AGM battery at.

Agm vs Standard Battery Charging: Do You Have To Use AGM Charger On AGM Battery?

There are a variety of types of lead acid batteries on the market and each one works slightly differently. They all do the same thing, and that is provide power to something, and they all do it in roughly the same way with plates and electrolyte in between, but they hold the electrolyte in different ways and can run out of juice in different ways.

This means that they need charged in different ways. After reading this, you will understand the difference in charging an AGM battery verses charging a standard battery, and the best charger for each one.

Agm vs Standard Battery Charging

Do you have to use AGM charger on AGM battery?

What Does Charging Do?

First though before getting into the specifics of different types of chargers and which to use with what kind of battery we will cover what charging actually does. In a battery you have the electrolyte which is a liquid that holds the electrons.

The electrolyte is a mixture of sulfur and some other parts. Over time, the sulfur and the electrons with it stick to the metal plates inside the battery and builds up. When the electrons are stuck to the plates, instead of being able to flow thru the battery, that is when the battery is considered low on charge.

By charging the battery a pulse is sent into the battery and it breaks the sulfur build up off the plates. This frees the electrons and puts them back into the electrolyte where they are able to move thru the battery again and provide juice to whatever the battery is connected too.

Standard Battery

In a standard battery the electrons are housed in just the liquid mixture and a part of that mixture is water. When you recharge a standard battery, the charger normally puts off a strong pulse and charges quickly.

This is because standard batteries with liquid in them are not hurt by being charged fast. By charging the battery fast you can start using it again quicker.

The problem with charging a battery fast though is that it causes a lose of the water inside of the mixture. It evaporates off and heat is formed. A standard battery though the heat goes away with the water that is being lost and normally it doesn’t get hot enough for damage to occur.

Charging a battery fast though can also lead to over charging. This is when pulses are still being sent in, but there is no more sulfur to be broke off.

Over charging of a standard battery again does not cause much damage and just causes water to be lost. The reason this water lose isn’t a big deal though, is that water can be added back into a standard battery making it so it will function the same.

AGM Battery

AGM battery

An AGM battery

An AGM battery on the other hand though, you can not add water back to it. This means that water that is lost has to get back in a different way. For an AGM battery there is a catalyst such as platinum, that is able to turn the hydrogen atoms that are created when charging back into the water.

In an AGM battery there are glass matts that absorb the liquid and AGM stands for Absorbed glass matts. These matts suspend the electrolyte and makes it so the battery does not leak.

Since water can not be added directly back to an AGM battery though, then once the catalyst is gone inside, it is gone, so you should do everything to prevent the need for it.

When it comes to charging, that means you should charge an AGM battery low and slow. This is because if you add a low amount of pulse over a longer period of time not as much heat will be made, so the battery won’t get as hot.

Also, if you charge it slowly, then you are less likely to over charge the battery and cause damage. However, you don’t want to under charge the battery either. That is why they make chargers designed for AGM batteries and are labeled as that.

A charger labeled for use with AGM batteries is normally more of a battery tender. This means that it has computers that can monitor the level of charge in the battery. As it gets closed to being fully charged, then the charge can slow down, so as not to over charge the battery.

These special chargers will normally stop charging once the battery is fully charged, and won’t start recharging again till needed, meaning they can be left connected.

Do You Have To Use AGM Charger On AGM Battery?

So, now that you understand the difference between a standard charger and an AGM charger, a lot of people will ask if you have to use an AGM charger for an AGM battery. The technical answer is no you don’t have too.

The standard charger will charge the battery and if monitored will not cause harm to the AGM battery, especially if used on the lowest setting, but if you are not careful, then it will over charge the battery and lead to the AGM batteries life being cut short.

That is why even though you technically don’t have to have an AGM charger for an AGM battery, it is a good idea to have one. You spent good money on an AGM battery, so make sure you charge it properly and don’t damage it and get a charger designed for it.

AGM battery charger

Though you technically don’t have to have an AGM charger for an AGM battery, it is a good idea to have one


AGM and standard batteries both charge in the same way. The charger applies a pulse to the battery and this breaks the sulfur off the plates and restores it to the electrolyte allowing the electrons to flow freely.

The difference is when you charge a battery it loses water, and this is especially true with strong standard chargers or if you over charge a battery. With a standard battery this isn’t much of an issue because you can add water back, but with an AGM battery you can’t add water back.

It has a catalyst inside the turn the hydrogen back into water, but once the catalyst is gone, the batteries life will be almost over with. That is why you should use an AGM battery charger on an AGM battery to keep the life of the battery up and prevent water lose and over charging.

How To Find Ground Fault With A Multimeter?

Multimeters can be used for all kinds of purposes. One of those is locating a ground fault in a circuit. After reading this article you will know what a ground fault is, why it is bad, and how to use a multimeter to find one.

We will go thru the steps required to safely find a ground fault so it can be fixed and not cause harm.

How To Find Ground Fault With A Multimeter

How to find ground fault with a multimeter?

Ground Fault

Before going into how to find a ground fault with a multimeter though, it is a good idea to know what a ground fault is.

A ground fault is when wiring is worn, chafed, pinched, or bad and current is getting out of the system and into the ground.

Normally current either gets to the ground thru the circuit and a dedicated wire or the current doesn’t go into the ground at all, but instead stays in the circuit.

Dangers of Ground Fault

The reason why ground faults are dangerous is that if current is getting out it means something is damaged in the system. The thing might still function properly, or it could not have enough power going thru the circuit and the item might not function right.

Ground faults are also dangerous because if you are working on the item that has a fault and touch the part where the fault is, then the current can go thru you.

This will only happen if the thing is on though, so if working on something make sure it is off. You may touch the bad wire though unknowingly with normal use and get shocked. Even worse, depending on what the bad wire touches it could cause a fire or worse shock.

If the wire with the ground fault touches water, then it can shock everything in the water. This is why you need to find ground faults as soon as possible, if you suspect one.

Using Multimeter To Find Ground Fault

Using Multimeter To Find Ground Fault

Using multimeter to find ground fault

One of the easiest ways to find a ground fault is by using a multimeter. This is good because a lot of people already have multimeters on hand. Continue reading this and you will learn the steps required to safely find a ground fault.

Any multimeter will work for finding a ground fault. You don’t need the most expensive one on the market and there are a lot of different ones on the market.

All you need is a multimeter that is reliable. Make sure the object that you are going to be testing is unplugged and off. Then also make sure that the probes are connected to the multimeter.

Once his is done set the multimeter to the ohm setting. If your multimeter has more than one position for the ohm setting, then set it to the 1x position.

After you have the multimeter on and set up, it is time to do the ground fault test. Touch one probe to a terminal and touch the other to the device housing or mounting bracket.

Now, you move the first prob that is touching a terminal to another terminal. If the multimeter reads anything besides infinity during any part of the test, then there is a ground fault.

If you are testing something with multiple circuits, then you can use the multimeter to determine which circuit is bad as well.

If for example you have a battery that is connected to a fuse, then you can connect on probe to the battery side and then one to the fuse side. Start turning off fuses unitil the reading is correct or the infinity symbol and then you will know which fuse is bad. Talk about battery, if you need a tool to maintain your car battery, i recommend you using the best battery tender, i used it and it is great tool to do that.

The thing about finding ground faults in a circuit that can be annoying is figuring out which one it is, but it really isn’t that hard. You just have to test each on until you find the bad one.

This requires being patient and taking your time. If you stay patient and take your time though, then you can find which circuit is bad and know which one to repair, instead of having to fix them all.

Fixing Ground Fault

The best way to fix a ground fault is just to replace the bad wire. This is the simplistic type of ground fault to fix. If it is just one wire or a few wires that are bad or old, then you can remove them and put new ones in.

Sometimes though the ground fault is in a specific part. If that is the case, then you have to replace that whole part. It is normally not worth the trouble or safe to fix the part instead of replacing it.

Also, you should never use a part with a ground fault for the danger or damage that it can cause. Just order the new part and replace the whole thing, to fix the ground fault problem.


find ground fault

Ground faults tend to not be hard to fix, but they can be a real struggle finding sometimes especially depending on how big the system or circuit is.

The trick to finding the ground fault though, is breaking the system down into smaller sections where you can and using patients and going slow when you can’t break it down.

Then you just need a simple multimeter that is reliable to start testing. To test for a ground fault connect one probe to a terminal and the other to the case of the object and then move the first probe from terminal to terminal.

If the multimeter on the ohm setting gives any reading besides infinity, then there is a ground fault. If the system has breakers, then you can connect on probe to the terminal and the other to the breaker.

You can then shut the breakers off, until you find the one that is causing the bad reading. That way you know which part of the system you have to work on.

Once the ground fault is located, then it is easy to fix. You just have to replace the worn or pinched wires with new ones and the problem should be solved. Sometimes though it is a whole part that is bad and you will have to replace it. Grounds faults are dangerous though and should be taken serious. They should be found and repaired as soon as you are aware of one existing.

Difference Between Battery Charger vs Battery Maintainer?

When your battery is dead in your car, mower, or other items that use an array you might want to charge it instead of buying a new one. This is because a lot of times when the power is low in a battery it can be restored, and the battery is not truly dead.

This is good because it saves you money from having to buy a new battery. However, what is the best way to restore the power to a battery? There are a few options on the market, and it is important to know the differences between these options.

The options we will look at in this article is regular battery chargers versus battery maintainer. After reading this article, you will know what each one does and when to use each one.

Battery Charger vs. Battery Maintainer

Difference between battery charger vs battery maintainer?

What is Battery Charger?

A battery charger is just what it says. It is a device that charges the battery. The way a battery charger works are it converts power from a wall or battery bank into a pulse that goes into the battery.

The pulse causes the sulfur that is built upon the plates in the battery to break off and return to the electrolyte inside the battery. This is how the charge is restored.

With a battery charger, you can set a specific amp amount, and that controls how much of a pulse goes into the battery. You want to make sure to use a proper amp that will not damage the battery.

It is generally better to charge slower, than faster because when you charge to fast it can cause heat to build up in the battery and this will damage it. If the battery burst, then it will be permanent damage.

Also, you want to make sure to know the kind of battery you are charging because some require specific types of battery chargers.

Trickle Charger

A special type of battery charger is a trickle charger. A trickle charger applies a small amount of voltage to a battery. This causes it to charge slowly and not to get too hot.

Also, the advantage of a trickle charger is that it reduces the chance of overcharging your battery. When charging a battery you want to make sure to charge it all the way or else the lifespan of the battery will be hurt, but you also don’t want to overcharge the battery because that will ruin the battery too.

The charge from a trickle charger is constant, but it puts out a charge that is equal to the batteries rate of self-discharge. Trickle chargers are still not designed to stay connected to the battery.

Even though they reduce the risk of overcharging, it still isn’t good to use them for battery maintenance. If you want something for maintenance, then you should read farther.

Battery Maintainer

The best battery maintainer is similar to a charger, but not the same thing. A battery maintainer is designed for maintaining a battery more than charging it. While a battery maintainer puts off a charge, it does do so at a fast rate. If you want to get a battery use-able fast, then you should use a charger.

A battery maintainer puts off a charge that is controlled. You can set an amount, and it will not charge a battery past that amount. This means that it won’t overcharge the battery.

The battery maintainer can see how much charge the battery has and when it needs a charge, then it will turn on and start supplying a charge. Once the battery reaches the set threshold, then it will turn off and stop charging till the battery drops below the set point.

Outside of this feature through the battery maintainer still does the same thing as a regular charger of converting power into a pulse that goes into a battery that breaks the sulfur off the plates.

When To Use Each One?

battery charger vs tender

When to use each one?

So when should you use a battery maintainer over a battery charger? Well, the best time for a battery maintainer is when you aren’t going to be using the battery for a while.

You can leave the battery hooked up to the maintainer, and whenever it drops below the set point, it will get topped back off. This will keep the battery from draining all the way and going bad. When a battery sets and isn’t used, then it loses charge, and this hurts the life of the battery.

A battery charger should be used when a battery is dead and just needs a fast charge, and you can keep an eye on it, so it doesn’t overcharge.

Depending on the battery and charger you can get a battery back to full strength in four hours or so and then it is ready to use again. This is good if you are going to be needing to use the battery soon.

A battery charger though should not be left hooked to a battery for long periods though because it will cause damage.


So now you know the difference between a battery charger and a battery maintainer. You even know that there are a couple of types of battery chargers. You have regular battery chargers and trickle chargers.

You also know that battery chargers provide a constant charge to a battery and are designed to restore a battery to full power, but not be left hooked to a battery.

If you want to keep a battery charger or maintained, then that is what a battery maintainer is for. A battery maintainer will put off a charge up to a certain point and then when the battery reaches that point it will stop charging till needed again.

This means a battery maintainer can be left hooked up forever and are good to used to keep a battery in working order during long periods of not being used. Now that you know the difference you should be able to determine what one you should use for your situation.

Car Battery Won’t Charge: Why And How To Solve?

Dead car batteries are an annoying thing. This is especially because a lot of times they happen out of the blue. Sometimes it is from something simple such as a light getting left on and you can jump the car and get on your way, but sometimes the battery is too dead to jump and needs completely charged.

What does it mean though if your car battery won’t charge. Well, in this article we will look at some of the possibilities of why a car battery won’t charge and some of the solutions for that.

car battery won't charge

Car battery won’t charge?

Bad Alternator

The first reason why a car battery might not be charging is that the alternator may be bad. The alternator is what converts the spinning of the engine into power that goes back into your battery.

Normally, when a car and alternator is working properly, the alternator will charge the battery as you drive, so then it will have enough power to start the car again the next time you need it too.

If the alternator is bad though, then it is not providing any charge to the battery and their for the battery is not charging.

The alternator not charging the battery could be something as simple as the connections have came undone. If that is the case, then all you have to do is reconnect things, and it should start working properly.

Vibration while driving or wires going bad is how the battery and the alternator could become disconnected. If they are not disconnected though, then their must be something else going on.

You can run a test on the alternator by a automotive multimeter and see if it is putting off a charge. If it is not putting off a charge, then it is bad and must be replaced.

 alternator going bad

If the alternator is going bad, then it may not be converting as much energy to the battery

Getting an alternator replaced isn’t that hard and if you are mechanically skilled then you can do it yourself. If you aren’t though, then any shop can do it for you. If the alternator is putting off a charge, but it isn’t constant, then you might just have a bad belt.

If your serpentine belt is loose, then it could be slipping and not allowing the alternator to work properly. If that is the case, then you will need that belt replaced. Again, this isn’t that hard of a task to have done and isn’t to costly of a repair.

Bad Battery

Another reason why the battery may not be charging is that the battery itself is bad. A lot of things can go wrong inside of the battery. The battery could short itself out or get internal damage from shocks or vibration.

To find out if the battery itself is bad you can run some test on it. If the battery itself is bad, then you will have to replace it and get a new battery. A bad battery can not be repaired.

Also, if the battery shows visual signs of being bad, then it is time to replace it. If it has corrosion or leaks, then it is defiantly time to get a new battery. If the connectors aren’t corroded to bad, then they might be able to be cleaned off and this might allow it to charge properly again.

Another reason why a battery might go bad is just its age. As a battery is used suffer builds up on the plates and forms a crust. When the battery is being charged it breaks this suffer off of the plates.

battery itself bad

If the battery itself is bad, then you will have to replace it and get a new battery

Over time though the sulfur will not come off the plates all the way and won’t go back into the solution. Also, the sulfur eats the plates and over time and recharging the plates just disappear. As the sulfur is broke off the plates int he recharging process, a part of the plate goes with it.

Think of a rusted panel and how it crumbles, well the plates int he battery work the same way. If your battery is old it won’t recharge or hold a charge and again will have to be replaced.

Bad Charger

Another final reason why a battery might not recharge is that the charger you are using may be bad, not be the right type, or not be connected right. Some batteries require special types of chargers to recharge them.

If you are using a charger and it doesn’t seem to be charging your battery, then make sure it is the right type for that battery.

Another reason why the charge may not be charging the battery is your may not have it connected right. To connect a charger to a battery you want to make sure the positive lead is connected to the positive connector on the battery.

If it is not it will not work and cause damage to the battery. You then connect the negative to the negative pole on the battery. Once connected make sure you plug the charger in and set it on the right amps or speed of charge to match the battery.

If these things don’t work, then the charger itself might be bad. Try a different charger and see if it works with the battery you are trying to charge. A battery charger could get a short in it just like a battery can or the inside components could go bad. If you want to buy a new battery charger, this is the best battery tender for you.

charger itself bad

If the charger itself is bad, you should get a new one

A battery charger has to convert the AC or DC current into current that the battery can use and this converter mechanism on the inside of the charger might go bad or stop working. This is especially the case if the charge is old, or if the charger has not been stored or used right in the past.


So as you now know there are a few reasons why a car battery might not be charging. The alternator inside the car could be bad or you could have a loose belt inside the car. The battery itself could be bad. The battery could have damage that you don’t see or it just might be old and wore out.

If it has been recharged a bunch, then it just might not be able to be recharged any more. Lastly, the charger could be bad if you are trying to use an external charger or it could be connected wrong. After you have made sure it is the right charger and is connected right, you might need to try a different charger to see if that fixes the problem.

Now you have a better understanding of why a car battery won’t charge and should be able to trouble shoot it for the situation that is at hand for you and your current situation.
