How To Read A Battery Charger Amp Meter?

When charging a battery, it is important to know how many amps are going into the battery. To do this, you can use the amp meter on the charger.

After reading this article, you will know how to read a battery charger amp meter properly. We will break it down into simple steps, so anyone can read their meter after reading this article.

Connecting Battery Charger

Before being able to read the amp meter on your battery charger or battery tender, you must be able to connect it. The first step to connecting it is to open the car hood and disconnect the battery from the car.

To do this, you just remove the positive and negative leads from the diode. If you don't know how to disconnect these leads, it isn't that hard.

First, you will need to get a screwdriver for most cars or sometimes a socket. You then just loosen the screw but don't remove it all the way. This loosens the clamp on the end of the lead.

Once the clamp is loose enough, you just take the lead off. You then do the same to the other one. It is best to disconnect the positive first and then the negative. Also, while disconnecting these make sure the car is off, and the key is not in the ignition.

Once you have the leads of the diodes, you just have to connect the battery charger. Depending on the type of battery charger you have might determine how you do this. Most chargers have clamps of some sort though. You also try best battery tender for car , it better than than battery charger, every one should have one. 

All you do is take the wires with the clamps on them, they will probably look like jumper cables, and then you hook the clamps to the post. The positive one needs to go to the positive and the negative needs to go to the negative.

If you don't know which is which then just look at the post and the positive will have a plus sign on it. If you can't tell the clamps apart, then they should have a sign on them as well. A general rule of thumb though is that the positive clamp is red and the negative is black.

Now that you have the battery charger connected it is time to read the meter. To read the meter, you will have to plug the battery charger in and then turn it on. When you turn it on the needle on the meter will move.

If you have the charger set to ten amps, then the needle will move to that point. As the battery charges the needle will drop. Once the needle is down to about half of whatever amount the charger is set to, then that means it is fully charged.

Sometimes there may be more than one needle. The needle that moves to the amount you have it set to is the one that is telling you how many amps the charger is putting out. The other needle is telling you how much charge the battery has.

If yours has two needles and they work this way, then you know the battery is fully charged when the needles are on top of each other. Reading the meter on your battery charger is that simple.

Multiple Scales

One last thing to know is some battery chargers also have two scales on the amp meter if it can output at different amps. For example it is not to uncommon to see a 2amp scale and also a 10amp scale.

They are normally in different color numbers. When looking to see where the needle lines up you need to make sure you are reading the correct number for the output. This way you will get an accurate result. Make sure you have the dial set to what you think you have it set to.

Sometimes the know can get moved or a switch flipped when moving your charger around and that could lead to you charging at a different amp then you though or you reading the wrong scale.

Reading Digital Meters

Some newer or more expensive battery chargers may have meters on them that are digital. This is nice because it makes them easy to read, but can be confusing because you might not be reading the right thing.

To read the amp output of your battery with a digital reader you will need to make sure it is on the right setting. To do this you can push the button on the control. This will cycle thru the different read out options that yours has.

Some other ones besides amp might be the volt output. To make sure that it is the amp output that you are reading you can click the button and ccle thru till you see it say amp on the screen with the number.

This will make it so you know you are reading the right thing. If it says volt or something else you will need to click the button and go thru the different numbers till you are at the right one.

Conclusion

Reading a battery charger amp meter isn't all that hard. All you have to do is make sure you are looking at the right scale and when you have it connected you look at the number that the needle is pointing too.

The number is how much charge the charger is putting off to the battery. When the battery gets full it won't be pulling as much charge. This means if charging at 10 amps the needle may only be at 2 amps and if charging at 2 amps the needle may have barely moved.

Reading digital scales is even easier because you just have to read the number displayed and make sure that it is amps being displayed. After reading this you should be able to read your battery charger amp meter and know when your battery is done charging.

How Long To Charge A Car Battery At 2 Amps?

Charging times for a battery can vary by a few different factors. One is how much charge the battery has, and two is how many amps you are charging it at.

After you read this article, you will learn how to calculate the charging time for your battery and also the way to charge your car battery.

You will also learn why two amps is an ideal charging power. Continue reading to learn how to figure out how long it will take to charge your car battery. For charging a battery, I recommend you should have the best battery tender to do that. It is the best tool to recharge and maintain battery.

How Much Power Left?

The first thing to do before figuring out the charge time for a car battery is figuring out How much charge the battery has left. The best way to do this is to first read the battery and see how many amps it is.

Car batteries range in amp hours from 20 to 60 for most vehicles. Once you know the amp hours, you then can hook automotive multimeter  or a car battery tester up to the battery to read the charge.

A car battery is 12.6 volts when fully charged, so knowing this depending on the reading you can calculate how much charge the battery has.

For example, if it reads 6 volts, then you know that it is roughly fifty percent charged. You can then take the number of amp hours the battery is and multiply it by the percent to see how many amp hours are left. For example, if you have a 48 amp battery and it is fifty percent charged, then it has about 24 amps left.

Using this method you can find out how many amps are left in any battery. Once you have calculated this, you are close to figuring out how long to charge your battery to get it back to the full charged. Before we get into that though, I will touch slightly on what an amp hour is.

How much charge the battery has left?

What Is An Amp Hour?

Amp hour is how much power is put out to run a specific function of the car for a set amount of time. If you have a 50 amp hour battery, then it can put one amp out for fifty hours before being completely dead.

Certain things on your car draw a specific amount of amp hours. There are a lot of factors that go into how many amp hours something draws though.

For example, headlights can use 8-12 amps for most modern halogen bulbs, but in older muscle type cars they could use as much as 20 amps. This means if you have a 50 amp battery and headlights that draw ten amps, then they could run for five hours.

There is more than just headlights though that draw amps. That is why on short trips your battery may nor get completely recharged, which is where charging might become needed if you take a lot of short trips.

This is especially true in the winter months. Now that you know more of what an amp hour is we can get back to calculating how long it will take to charge your battery.

Calculating How Long to Charge Battery

How long to charge battery

So we mentioned one factor for charging the battery was determining how much power was left and the other is the amp rate that you are charging it at.

For this article and example, we will be using a two amp charger. Once you know how many amps are missing from the battery, it is a matter of just simple math to find out the time to charge. You take whatever amount is missing and then divide by two.

For example, if you have a 50 amp battery that is half depleted, then it has 25 amps missing. You then divide 25 by two since that is the charging rate to get 12.5.

This means it will take 12.5 hours for the battery to be completely charged. If you are using a different charging rate, then you just divide by that number instead.

Read on through to find out why two amps is a good recommended speed.

What amp to charge car battery? Why Charge at Two Amps?

The main reason to charge at slower speeds or two amps is that faster charging can cause damage to the battery. It can buckle the battery plates, and this will make the battery not function right and can damage other areas of the car.

Also, if the battery gets hot while charging then keep an eye on it and unplug it if it gets too warm. If you have a temperature gauge and your battery gets 125 degrees Fahrenheit, then you need to stop as soon as possible.

Another final reason that fast charging is bad is that it can lead to overcharging which hurts the batteries useful life.

Should you use 10 amp charger or 2 amp charger for car battery?

A lot of people wonder which is better to use a 2 amp or 10 amp charger for your car battery. Well, we are going to answer this for you.

The key thing to remember when charging a car battery if you don’t want to charge it too fast because this can cause damage to it. However, you don’t want the charging to take forever either.

A car battery is typically 48 amps. This means that a 2 amp charger will take 24 hours. A 10 amp charger, on the other hand, will take 5 hours.

For a car battery in most cases, it is okay to use a 10 amp charger and is normally the recommended amount. This is because it charges fast enough to not have to wait forever, but it doesn’t charge so fast that the battery will be damaged.

So, if you have to choose between  2 amp or 10 amp charger the next time you are charging your car battery, it is okay to use the 10 amp charger.

Conclusion

Enjoy your car

Enjoy your car!!!

Finding out how long to charge a car battery at two amps isn’t that hard. It takes some basic math that anyone can do and also some basic tools that are easy to use.

You have to know how much charge is left in your battery. Convert that to amps, and then divide the missing amp hour amount by two to figure out how many hours it will take to fully recharge the battery.

If the speed you are charging at is different, then the math is the same steps, but just with different numbers. This means that now you should be able to calculate how long to charge any battery.

How Many Volts Is A Motorcycle Battery?

You may know that different types of batteries have different charges or volts to them. This is because they need a different amount of power to operate.

For example, your TV remote doesn’t need a lot of power, so it doesn’t use many volts. This means that a TV remote would have fewer volts in it than a car battery.

In this article though we will look at how many volts are in a motorcycle. Is it the same as a car battery or less? Well, once you are done the reading, you will know how many volts is a motorcycle battery and also anything else related to this that you might need to know.

How many volts is a motorcycle battery?

Maybe you’re interested:

Are Car And Motorcycle Batteries The Same?

Well, I am not going to waste your time here. We are going to get right into answering some questions. The first one we will look at is are a car and motorcycle batteries the same voltage? The answer to this is it depends.

Pretty much all car batteries have a voltage of 12.6 when fully charged. They are called 12-volt batteries though. The charge can jump to a range of 13.6-14.6 volts when the car is running. That is because the alternator is feeding the battery charge and it isn’t being drawn that fast.

The reason why it depends is depending on the type of motorcycle you have will determine the type of battery that is in it. Some bigger motorcycles might use standard car batteries or at least they use 12-volt batteries.

Think of your Harley Davidson and chopper type motorcycles. These bigger rides do use 12-volt batteries, so they are the same as a car battery. This means that you can charge them using something that is designed to charge a car. Some motorcycles don’t have this size battery though.

What Size Do They Have?

If they don’t have 12-volt batteries, then what size do they have? Well, some smaller motorcycles and especially scooters have 6-volt batteries. This is because they don’t use as much power when driving.

Also, by having a smaller battery on the vehicle, it cuts down on weight which can help on speed. Small things such as crotch rockets you want to be lit so they can go fast. These little rides have smaller batteries to help with this.

A 6-volt battery though when healthy is more than that, just like with a bigger battery. A typical good 6-volt battery has 6.3 volts. This voltage again jumps some while the motorcycle is running. When the motorcycle is running the charge is normally around 7 volts or so when it is a new good working battery. You can use a car battery tester or a automotive multimeter to check how many volts it has exactly.

Why Is The Voltage Higher Then What Says?

The next question you might have now that you know the voltage of the different types of batteries is why is the voltage higher then what the battery says?

Well, we have already discussed why the voltage is higher when the motorcycle is on, but the reason the voltage is higher than advertised even when the vehicle isn’t running has to do with how the battery is made.

Most batteries for cars and motorcycles are lead-acid batteries. This means that they have a lead-acid mixture inside of them that holds the charge. The electrons move thru this and into the different parts of the car.

This is a really simple explanation but gets the job done. The electrons are broken into compartments called cells. Each cell in a battery holds 2.1 Volts. This can still range some, however.

Since the electrons are moving from cell to cell and then into the parts of the car, when you turn the motorcycle off, one cell might end up with more electrons than a neighbor.  This is why if you measure the volts of each cell, they will be different.

One cell may not last as long as another cell either. This means you might end up with a cell that can only hold 1.5 volts while the rest are holding 2.1 and the reading would still be close to the proper amount of 12 or 6 volts.

The loss of the ability to hold the charge can come from a variety of reasons, but the main one is sulfur build up. I am not going to go into a lot of detail of why a battery might not hold a charge though because there are many reasons, and that is a whole different article.

So, now you know the charge is broken into cells. For a 12 volt battery there are six cells, and for a 6-volt battery, there are only three cells. This helps explain why the 6-volt batteries are smaller. They have half the amount of cells in them than a 12-volt battery.

The cells are held in place with a plastic enclosure. This enclosure is the main part of the battery you see, and the two end cells have diodes that pop out of the top of the case that is your positive and negative leads.

This is where the wires hook up. Knowing the basics of how a battery is made up though can help you with understanding how the different voltages work and why they have different voltages.

Need to recharge your motorcycle battery, let use the best battery maintainer for motorcycle, it is an essential tool of biker.

Is One Type Of Battery Better?

The last question we will look at is if one type of battery is better or not. This means should you try to buy a motorcycle with a 12-volt battery or get one with a 6 volt or does it matter.

The answer is it doesn’t matter really battery. Both 12-volt batteries and 6 volts do what they are supposed to do. They are relatively the same, and the only thing different is the number of cells. They will still drain the same way and still age the same way.

Also, the same things that might cause one to not last as long will affect the other. This means that you shouldn’t make your motorcycle purchasing decision just based on the size battery it uses. Buy the motorcycle that makes you happy and doesn’t worry about the size of the battery.

Conclusion

Now you know that motorcycles have two different standard battery voltages. Some motorcycles use a standard 12-volt battery. These are your bigger motorcycles that need the power and aren’t worried about cutting weight. Smaller motorcycles though use a 6-volt battery.

This is because the battery is smaller and they don’t need as much power. You also know how a battery works now and that they all drain the same way. When buying a battery just take the old one with you, so you make sure you are getting the right voltage for your ride.

Battery Minder Vs Battery Maintainer: What Are The Differences?

Keeping battery charged is important for all kinds of things that use them. No matter if it is your car battery needing to stay charged or a motorcycle, lawn mower, or golf cart, there are a few options of how to do it.

You have trickle chargers, battery maintainers, and battery minders. We already have an article about the difference between a battery maintainer vs trickle charger, so here in this article, we are going to look at the differences between battery minder vs battery maintainer.

Once you have finished reading this, you will know the difference and have a better idea of which one you should use.

Battery minder vs battery maintainer: What is the difference?

Battery minder vs battery maintainer: What is the difference?

Battery Minder Vs Battery Maintainer, How They Work?

First, we will talk about how both best battery maintainers for car storage and battery minders work. They work in similar ways. Both have alligator clips on them that run from the control converter that you hook to the battery.

The positive goes on positive and negative on negative. They are simple to use. Once you have them hooked up properly, you just plug them into a wall.

They convert the AC into the voltage that the battery needs. Some have dials that you have to turn to control the output.

What Is The Same?

What is the same between a battery maintainer and a battery minder?

What is the same between a battery maintainer and a battery minder?

Outside of how they are used, that is not the only similarity between a battery maintainer and a battery minder. Another thing that both have in common is that they provide a float charge.

This means that the charge that they send to the battery fluctuates depending on how charged the battery is. This is important because it keeps the battery from getting overcharged.

If a battery gets overcharged, then it can cause damage to the battery or even worse damage to the car. An overcharged battery could catch on fire, and that would ruin the car and the area where it was being stored.

Since battery maintainer and battery minders have float charge built in, it means that you can leave them hooked up pretty much indefinitely.

This makes them nice to use if you want to keep a battery charged thru the winter or a long period of the device not being used. You just hook it up and forget about it until it is time to use the thing again.

Another nice thing is you don’t even have to pull the battery if you don’t want too. You can hook up battery maintainers and battery minders straight to the battery while it is still in the vehicle.

What Is Different?

Copper sulfate on car battery

Copper sulfate on car battery

If battery maintainer and battery minders have so much in common, then what makes the two different? Well, that is a good question. The only real difference between a battery minder and battery maintainers is that a battery minder has a desulfuration feature.

The sulfur build up is what kills batteries. When the cells start getting sulfur in them, then they don’t charge all the way. The way the battery minder beats and prevents this is by sending a pulse into the battery. This destroys the sulfur that is in it and helps your battery last longer.

Built into this desulfuration feature is that most battery minders also have three modes. They have the charge mode, but then they also have a maintenance mode and conditioning mode. These other mods can be used to help keep your battery in top shape.

The maintenance mod can remove the sulfur without having to charge the battery. The conditioning mode can help keep the battery in a stage that it will hold a full charge. It lets the battery run down, so then it can be recharged all the way before running down again.

This is important because to some extent batteries have memory. This means that if a battery doesn’t discharge all the way, the next time you let it run down it will rain faster. Then it also won’t charge back up to full when you charge it. The conditioning feature helps prevent this from happening with your car battery.

Which Is For You?

Which is for you?

Which is for you?

So which should you get a battery maintainer and a battery minder? Well, both are good and honestly better than trickle chargers.

When it comes to choosing between a battery minder and a battery maintainer though you have to consider if the extra features of the battery minder are worth it.

For most people that answer will probably be no. It takes awhile for sulfur to build up in a battery, so the desulfur feature of the minders isn’t all that useful unless the battery is going to be sitting on a charger for a long time. I am talking more than just the winter here.

Also, the conditioning features aren’t that helpful. Car and vehicle batteries are used to getting partially drained and then recharged, so they don’t have the same level of memory as say a laptop battery or a cell phone.

This is because those things aren’t made to be plugged in all the time, but a car battery has the alternator charging it whenever you drive, and then you park but might leave the radio on or something that draws the charge and then start driving again, and it gets recharged.

My point is car batteries are constantly being charged, so the conditioning won’t help the battery last longer.

When Is Battery Minder Worth It Then?

 

With that said, at times you might want a battery minder over a battery maintainer. Like has been mentioned, if you plan on leaving something to sit for a long time, then the desulfuring of the battery would be nice.

Also, a battery minder would be more desirable if the battery you are keeping charged is expensive. If you have something with an expensive battery, then it is worth it to take the extra effort to keep that battery running and charging properly, so you don’t have to replace it all the time.

Conclusion

So, to recap battery maintainer and battery minders are similar. They both offer float chargers which means you can leave them hooked up as long as you want.

The main difference is battery minders offer battery maintenance where battery maintainer don’t. This means if you want to remove the sulfur from your battery to help it last longer then you need a battery minder.

For most people, though they aren’t leaving their battery hooked up long enough to get the benefit from this, so battery maintainers do the job just fine of keeping the battery charged.

Trickle Charger Vs Battery Maintainer: What Are The Differences?

There may be times where you aren’t going to drive your vehicle for awhile, and if that is the case, then the battery might go dead.

For example, if you have a classic car that you don’t drive in the winter, then the battery might die by next spring if you do not keep it charged.

There is another maintenance to do with car that are going to set beside keeping the battery charged, but that is for a different article.

Here we will cover the options you have for keeping a battery charged and which one is better. The two options that will be covered is a battery maintainer vs a trickle charger.

After reading this, you will know the difference and which one you should use.

Trickle Charger Vs Battery maintainer

What Are The Differences Between Trickle Charger Vs Battery Maintainer?

Battery Maintainer

A battery maintainer hooks to the battery like a pair of jumper cables would. It is a box with a few controls on it and some cables coming out.

You hook the jumper cable like cables to the battery and then plug the box into the wall. The battery maintainer then converts the AC power from the wall into the type of power that your car battery needs.

The good thing is battery maintainer  are known as smart. This means that they are programmed to be able to tell how much power is inside of the battery.

When the battery does not meet a specific lowness, then the battery maintainer  will not charge it. If the battery falls below the required point while the battery maintainer  is still hooked up, then it will start to charge again.

This is nice because you don’t have to worry about overcharging issues which we will talk about later.

Bonus: If you want to have a smart charger for fully charged battery, this is the best battery maintainer for car.

Trickle Charger

A trickle charger is similar to a battery maintainer . For the most part, they can look a lot alike. A trickle charger still plugs into the wall and converts the AC power into power usable by the battery.

It also hooks to the battery in the same fashion with jumper cable like cords. The trickle charger though is not smart.

It continually applies a small charge to the battery. This means that even once the battery is fully charged it will still keep charging it.

A trickle charger applies its power to the battery at a slower rate than a battery maintainer . This means that it takes them longer to get the battery fully charged.

This can be a good thing if you are just plugging it in overnight, but not useful if you want to use it to keep a battery charged for extended periods.

A trickle charger though is cheaper than a battery maintainer  though, and a trickle charger has an excellent alternative use that we will talk about farther.

What Happens if Overcharge Car Battery?

So why is it essential to not overcharge your car battery? Well, if a car battery gets overcharged a lot of negative things can happen.

First, a fire could occur. This is because if a battery gets overcharged, it will start getting hot and could explode. This is an extreme thing but is a possibility, and if it happens, then you will lose your car, garage, and a lot of other things.

Another thing that happens to a car battery when it gets overcharged is it causes it to not hold a charge as well. The battery becomes dependent on being on a charger.

This means that the battery will die more frequently and you will need to replace it if you don’t want to deal with it needing to be charged all the time.

Lastly, even if the battery does not catch on fire, it can still crack or bust to the point that it leaks chemicals on the surrounding parts if it gets overcharged.

These chemicals are very corrosive and would ruin anything they touch. Also, a battery that bust has to be replaced.

Due to all these reasons, it is a good idea not to overcharge your battery. That is why for the long term you want a smart battery charger.

Use of Trickle Charger

There, however, is an excellent area where a trickle charger comes in handy, and that is if you have a parasitic drain that you can’t find.

A parasitic drain is when something is drawing power from the battery when it is off and causing it to die. Finding electrical issues can be time-consuming for a car, but if you know you have one, then you can use a trickle charger each night to keep your car charged in the morning.

This is because it will release a slow charge to your battery, that should be enough to counteract the drain that is occurring on it. That way you don’t have to worry about jumping your car every morning.

Another time where trickle chargers may come in handy is if you have an older battery. As a battery gets older, it might start losing power with cold temperatures.

This means if you live in an area that gets cold and you find your battery is dead or low a lot the morning after a cold night, that it is being drained.

To prevent this, you can use a trickle charger on nights that you know it will be cold while your car is parked in the garage.

Then you just have to unhook it in the morning, and you are ready to go about your day without having to jump your car.

Conclusion

Trickle chargers and battery maintainers both have their uses. Trickle chargers are good for if you want to leave your car hooked up overnight or for short periods, but since they don’t monitor how charged, the battery is they can overcharge the battery.

A battery maintainers , on the other hand, is smart and will not overcharge the battery. We have given the reason why overcharging is bad on your battery, so that is why battery maintainers are the way to go if you are going to keep the battery on a charger for a long term.

Also, battery maintainers charge faster, so if you need a quick charge, then they are the way to go as well. Now though you know the difference between a battery maintainers and trickle charger, so you can figure out which one is right for you and your needs.

What Is A Battery Maintainer?

So there are many ways to charge a car battery and depending on the circumstance you are in one might work better than others. Most people know that once the car is running, the car will charge the battery itself with the alternator, but sometimes you can’t get the car started.

A common solution to this problem is jumping the car, but sometimes this won’t always work. If the battery is too low to jump or you don’t have another car around to use, then you need a different option.

In this article we will cover one of those different options, and that is a battery maintainer. After reading this you will know what is a battery maintainer, the advantages to one, and how to use it.

What is a battery maintainer

What Does A Battery MaintainerDo?

The simple answer to what a battery maintainer does is it charges your cars battery. The way it does this is by converting an AC charge from a wall outlet, into a charge that your car battery can hold.

A battery maintainer is designed to fully charge and maintain most batteries in ways that avoid the potential damaging effects that can be caused by a trickle charger.

You connect the battery maintainer to the battery and then plug it in. The maintainer converts the charge from the wall and sends it into the battery. It really is that simple.

Advantages To Battery Maintainer

The advantage to a battery maintaineris that you don’t need to have jumper cables or another battery around to use it. As long as you have a wall outlet, then you can recharge your car battery. This is why it is great to have one at your garage or house.

Another advantage to the battery maintainer is it is programmed so it won’t over charge your battery. This is good because over charging a car battery can cause major damage to it. It can cause it to leak, get hot, and other issues.

The way the maintainer keeps from over charging the battery is it can tell how much charge is in the battery. It is preset to a specific amount and when the battery it is connected to gets to that amount it will stop charging. This means you can leave it hooked up in defiantly.

One use for best battery maintainer then is to hook it up to a car every night to keep the battery charged if you know that the car has a parasitic drain. This way your car won’t be dead and needing jumped every morning.

Also, car batteries loss charge over time just from sitting. This means if you have a car that you don’t drive often, then the battery might die. That isn’t a problem if you have a battery maintainer though.

Instead of having to drive the car once or twice a week that you leave sitting, you can just hook it up to the charger, and that will keep the battery ready to go when you do decide to drive that car.

How To Use Battery Maintainer

How to use battery maintainer

How to use battery maintainer?

So, how do you use a battery maintainer? Well, it is really simple to hook one up. Most people can do it in ten minutes or less and the more you do it the better you get. For most vehicles, you don’t even have to remove the battery.

If you do decide to remove the batter though, then be sure to lift the battery out from the bottom and carry it by the bottom because using the top can damage the battery.

To connect it without removing the battery though, you just remove the two terminals from the car battery starting with the negative for safety. Also, you obviously want to have the car off.

Then, clamp the red positive clamp from the battery maintainer to the positive battery terminal. You want to make sure that the clamp is tight and won’t come off unless someone removes it. You then take the negative clamp, and clamp it to the engine block or frame.

This is to prevent damage to the battery. You can clamp it to the negative terminal on the battery, but it is better NOT too. The only thing is you want to make sure you clamp it to metal and not to hoses and things.

Next you can switch the amp switch, if your battery maintainer has one, and then plug it in to the wall. You might have to use an extension cord to get it to reach all the way to the wall.

After this you want to look at the color light. If the light is red, then that means the battery maintainer is working and that it is charging the battery. If it is green, then that means that the battery is already charged up to the threshold on the battery maintainer.

Depending on how dead the battery was, it might take it a little bit to charge up. It is safe to leave it charge and go work on other things or come back in the morning. After a few hours when you come back the charging should be done and the light will be green.

Once the charging is done all you have to do is unplug the battery maintainer from the wall. You then have to disconnect it from the battery. After you have finished that you can reconnect the battery to the car.

The car will now start and is ready to drive. When reconnect the battery you want to make sure to use a wrench and have them tight. If the connection is not tight, it might cause it so the car will still not start.

How To Start A Car With A Dead Battery? (2 Ways)

Having a dead car battery can be one of the most frustrating things. You go out to your car in the morning or after work, put the key in and turn it and nothing happens or only a clanking sound happens.

This means you are probably going to be late to your next location because you got to figure out how to get your car started. Well, the good thing is a dead battery is something that can be fixed from right where you are at.

There is actually a couple ways to start a car with a dead battery. After reading this article you will know your options and how to start a car with a dead battery.

Options for Dead Battery

You have a couple main options if your car battery is dead and you need to get it started.

The first option is to charge the battery on a charger or a battery tender. For most people this isn’t a practical solution because when they find out their battery is dead it is because they are trying to go somewhere.

Also, not a lot of people have car battery chargers in there home. That means most people will use the other option and that is to jump the car. We will go into farther detail on how to jump a car below.

If you have a manual car, then you actually have a second option that people with automatic cars don’t have. If you have a manual car, then you can sometimes push start it depending on how low the battery is.

To do this though you need at least two people. The simple explanation of push starting a car is one person pushes the car, while the other person turns the key.

By pushing the car it causes the alternator to work and put off a charge to the battery. If the battery is not too low, this charge will be enough to give the battery enough juice to start the car.

How to Jump a Car With A Dead Battery

For those with automatic cars though you can’t push start them. This is because you can’t put the car in gear when it is off. That means you will have to jump the car.

To jump a car you will need jumper cables and another car. It really is that simple of only needing two components. That is why it is a good idea to carry a pair of jumper cables in your trunk for emergencies.

They do not cost much and you never know when you might need them. Now though we will go into how to use the jumper cables, so you can know what to do if you ever need to jump your car.

The jumper cables have two colored clips on them. One is normally red and the other is black. The red is positive and the black is negative. To jump a car you need to pop both cars hoods and open them.

This is so you can get to the battery. All you do is hook the alligator clips onto the metal terminals on each battery. Some cars have rubber caps over the terminals that you have to pop off.

How to jump a car?

How to jump a car?

Be sure to put the red positive clip on the terminal that is positive. To know which is which the positive will be marked with a plus sign. The black ground one goes on the other one that is marked with a minus sign.

On some vehicles the battery is positioned where you may not be able to get to the negative or ground terminal. If that is the case then there is most likely a piece of metal running along the battery that is connected to the ground part that you can hook the negative end too.

If you can not find such a piece, then you can just hook the negative end to any other piece of metal, such as the frame or side panel of the car.

The ground side just has to be connected to something metal to complete the circuit. The positive side is the only one that has to be connected to the battery.

Once you have the connectors hooked to both car batteries it is time to jump start the car. First you want to start the working car. Then, let the working car run for a minute or so.

This will allow the energy to transmit to the dead car. Once that is done you can try to start the dead car. If it doesn’t start wait a little longer and try again. Most of the time this works without any problems.

Once the dead car is running and can turn off the working car and carefully remove the jumper cables. You don’t want to touch the metal ends of the jumper cables whenever they are connected to either car.

Also, if you have gloves, then it is a good idea to wear them to protect you.

After the cables are removed, then you can close up the hood. It is a good idea to drive the jumped car a bit before turning it off to make sure that the battery will stay charged enough to restart it after turning it off.

If you don’t let the jumped car run long enough, then you will have to jump it again.

What if no other car

How do you jump a car if you don’t have another car around though? Maybe you are home alone and don’t want to call someone to come.

Well, if you have a lawn mower, then it most likely has a 12 volt battery too (if you want to be sure it has how many volts battery, you can use the car battery tester to test), so you can use it to jump start your car. You do that in the same way as if you were using another car.

What if no other car

What if no other car

This is a useful thing to know in a pinch, but to prevent this from happening you can also by a portable battery pack.

They make jump start kits that you can carry in your trunk that has a battery and jumper cables connected to it. All you do is connect the cables and turn the device on.

Then you just start your car like normal. It is highly recommended that everyone has one of these that they carry with them. The key though is to make sure it is always charged and taken care of.

You may forget you have it in your trunk and then when you need it, it might not be working right. They normally aren’t to expensive and it is nice to have the peace of mind that you can start your car no matter where you are at.

Also, they are cheaper then a tow bill if you do get stranded somewhere.

Conclusion

Enjoy your trip!!!

Enjoy your trip!!!

So, if you end up with a dead car battery you have a few options. You can remove the battery and charge it, push start the car if it is a manual, or jump start the car.

For most people jumping the car is the best option and now that you have read this you know how to do it properly.

Also, you know you can use a mower in a pinch or get a portable jumping pack, so you won’t ever get caught unprepared with a dead battery again.

Car Battery Won’t Hold A Charge: Why And What To Do?

Your car battery is one of the key components in running your car. It is especially important when you go to start the car.

The battery provides all the electrical energy to run anything in your car that uses electricity. It runs the headlights, radio, and even the starter.

That is why if your  car battery won’t hold a charge it is a major issue because your car won’t start and you will have to jump it all the time. There are a handful of reasons why your car battery won’t hold a charge and also a few things you can do about it.

car battery won’t hold a charge

What to do if car battery won’t hold a charge?

Reasons Won’t Hold A Charge

1. One of the most common reasons why your car battery didn’t hold a charge is because something got left on.

If your dome light comes on when you open your door, then it might have got left on during the night by the door not getting closed all the way.

Also, your headlights might have got left on draining the battery. You will learn how to figure out if this is the case later on in the article.

Your headlights might have got left on draining the battery

2. Another reason for your battery not holding a charge is that you might have a parasitic drain in your vehicle. A parasitic drain is when you have something wrong in your electrical system that puts a small draw on the battery.

If you drive your car normally, then the alternator probably charges the battery enough that you may not notice this drain. If your car sits for a few days however, then it may end up dead when you go to start it from the drain.

A parasitic drain could be going on for months before you are aware of it and tracking one down can be a major headache.

3. A third reason for your battery to not be holding a charge is a bad alternator or serpentine belt. The alternator is what charges the battery while you are driving.

It is like a small generator and takes some of the mechanical energy of the engine spinning and turns it into an electrical energy.

If the alternator is going bad, then it may not be converting as much energy to the battery. This will eventually lead to the battery wearing down and not holding a charge.

Also, if the belt connecting the c to the motor is loose, then the alternator may not be working at its full potential and this too will lead to the battery not getting recharged all the way while driving.

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

4. The last reason for a car battery not holding a charge is that it is old. As a car battery ages the cells can not hold as much energy. Most batteries have dates when they were bought and if it has been awhile then that could be a reason.

Also, dirty connectors on the terminals can cause the battery to not get charged all the way and lead to it dying.

What To Do If Your Car Battery Won’t Hold A Charge

If your car battery is not holding a charge, then there are a few things you can do depending on why it is not holding a charge.

First you need to make sure the battery didn’t just die from something getting left on. If that is why it died, then you shouldn’t need to do anything to your car after jumping it. It will recharge on its own.

If it is a parisitic drain, then you might not notice it again until the car has sit again. If this keeps happening, then you have to try to find the drain to stop it from happening. If that is not the reason, then you need to find the reason.

If the car battery is not holding a charge from a bad alternator or serpentine belt, then you need to replace that part. You can use a volt meter and battery tester to see if the alternator is charging the battery while the car is running.

You can try to recharge it with best battery maintainer, maybe it will help your battery keep alive.

Most auto shops such as Auto Zone will do this for you for free. If it is the alternator, then you now know the problem and know it needs replaced. If it isn’t then you can move on to other things.

One of the things you can do even if you don’t know the reason is clean all the connectors on the battery. This way you will know that they are making contact.

Also, if the battery has been drained multiple times, then you can put it on a slow charger and this will help it hold a charge better.

If your battery is old, then you have a few options of things you can do. Most people might not have the money to replace their battery whenever it gets old, and the battery is something you forget about until it doesn’t work.

If you have an old battery and can’t afford to replace it, then you can try recharging the cells. To do this you buy a kit and then remove the battery cover to expose the cells.

You add the liquid from the kit using the directions and then put the cover back on. This gives the battery more conductive juice to help it hold a charge again and last a little longer.

Recharging a battery though is only a temporary fix and recharged batteries don’t hold a charge as well as new ones.

Conclusion

Enjoy your trip!!!

Enjoy your trip!!!

There are a lot of reasons why car battery won’t hold a charge. It could be something as simple as something just getting left on one time killing the battery, or it could be that you have a small parasitic drain weakening the battery.

Also, it might be that the battery isn’t getting charged all the way due to a bad alternator. Lastly it might just be an old battery.

Depending on the reason that the battery isn’t holding a charge, you can do a few things. You can replace the battery if it is old or try recharging it.

If the alternator is going bad, then you can replace it. If it is a parasitic drain, then you can hunt it down and stop it.

Lastly, if the battery was drained just from lights getting left on, you shouldn’t have to do anything besides drive some after jumping the car.

How To Tell If A Car Battery Is Dead?

A dead car battery is one of the most common reasons why your car won’t start out of the blue when you go to start it. It can be dead for different reasons, and sometimes it is genuinely dead while other times it was just drained.

This article will go into how to tell if a car battery is dead, and also help you figure out if it was just a one-time thing from being drained or if it is indeed dead and time to get a new one.

How to tell if a car battery is dead

How to tell if a car battery is dead?

Signs Of Dead Car Battery.

There are a lot of signs that your car battery might be dead. We will go into more detail of each in its section, but the main ways of knowing if your car battery is dead are slow engine crank, check engine light, and issues with other dashboard lights or electronic components.

Also, there are a few other less visible signs, but still important ones, especially when it comes to troubleshooting. Those are swelling of the battery and odd smell to the battery. If your car is not dead and you want to recharge your battery, i recommend you use the best battery maintainer for car battery, i think you will love it.

1/ Slow Engine Crank

The most prominent sign of a dead battery is a slow engine crank or clicking engine. The battery works with the starter to get the engine to turn over.

If the battery does not have enough charge left in it, then it can not get the starter going enough to get the engine to fire.

The first time a week battery tries to start the engine, it might work but will be slower and take longer. It is essential to be familiar with your car and how long it usually takes to turn over because if it is slow, it might be your last shot to start the car without jumping it.

If the battery is already too far dead, then instead of having a slow engine crank it won’t start at all. Instead, when you turn the key, you will have a clicking or grinding sound.

The more you turn the key, or longer you turn the key, the softer this sound will get because you are draining the battery even more. Once it is 100% depleted it won’t make a clicking sound at all.

2/ Power Features Not Working

The next most accessible sign to know if your battery is dead is to pay attention to the power features in your car. For example when you open the door if your dome light does not come on or is not as bright as it usually is, then that is a good sign your battery is weak.

Your battery also powers every other thing in the car. If you stick the key in the ignition with your door open and it doesn’t beep at you, then that is also an indicator that your battery is low or dead.

Other things you can turn on to confirm that it is the battery and not just a fault in that one particular system is you can turn your headlights on, your radio on, try to use your windows or even your wipers.

If the key is in the battery on position, then these will work if the battery is okay. If the battery is indeed dead, then none of these things will work. This is an excellent way to confirm a dead battery.

3/ Warning Light

Some cars will have a check engine light or battery light on the dash when the battery is starting to get old and wear.

If you get a check engine light or battery light, then that is an easy way to know that the battery is having issues though. Not all battery lights though mean the battery.

Depending on the car if other lights come on with the battery light coming on it could be telling you that the alternator or something else is going bad.

If you get any lights on your dash, it is a good idea to use a code reader on it or have someone do that for you so you can know precisely what is wrong.

4/ Swollen Battery And Smell

The last sign is a visual one that you have to check under the hood for. When you go to jump the car, you may notice that the battery looks swollen or smells funny.

This is because chemical reactions are going on in the battery and as it ages it starts to swell or smell.

If your battery is old, then this is a good sign to know that the battery being dead wasn’t just a one-time thing but will keep happening.

How To Know When To Replace Battery

How to know when to replace battery?

Sometimes the battery being dead is just a one-time thing or a fluke. You might not have shut the door all the way, and the dome light or headlights could have drained it. This has happened to most people.

The best way to know if your battery is truly dead or just got drain from an outside cause is to have a battery test ran on it. You can use a voltmeter or a automotive multimeter  and see how much charge it has, but this won’t tell you if it is going to hold it.

Also, you might have a short in a system drawing on the battery, and a volt meter won’t help you with that either.

The best thing to do is take your car to a shop or any auto parts store. They will have a battery load tester. This device hooks up to the battery like a volt meter and can give you a readout of the current voltage and any draw being put on it.

Also, you can run a road test and rev your car for around thirty seconds while the machine is attached. This will let you know if the alternator is charging the battery, how much draw is being put on the battery, and the health of the battery. If the battery is old, this is the best way to know if you should replace it or not.

Conclusion

So there are a lot of signs that a battery is dead or dying. There are a mix of visual symptoms and also audible signs. First just pay attention to when you start your car, and if it seems like it took longer to turn over, then you might want to have the battery checked.

Also, pay attention to when you get in your car. If lights don’t turn on or if the vehicle doesn’t ding once you put your key in when the door is open, then the car battery is most likely dead. It could have just got drained from accidentally leaving something on, but if it is old, then it is probably not holding a charge which means it is time to get a new battery.
