Posted by on April 14, 2018 | 0 Comments

car batteriesModern cars are getting more and more advanced with a lot of parts that require a lot of electric power. That’s why a good car battery is one of the most important parts of a modern car. A Bad battery can cause a lot of strange problems with your cause and even damage your electric parts.

 

A car battery may seem like a simple part and it does not matter which battery you choose, that’s totally wrong. Choosing the right battery can save you a lot of time and money. I’m working as a diagnostic technician and I’ve seen a lot of problems in cars caused by a bad/faulty battery.
That is why I decided to write this article. I have listed the top 5 best car batteries in my opinion to buy and I’m answering the most important questions about car batteries.

 

Because I know the importance of a good battery, I only listed the absolutely best car batteries on the market. You may find car batteries for a much lower price on other sides, but the lifetime of those batteries are much lower and a bad performance. My recommendation is to spend your money wisely and buy quality when you are looking for one of the most important parts of your vehicle.

Frequently Asked Questions about car batteries:

Q: What size of the battery should I choose?

A: The simplest answer to this is: Check what size of the battery that is fitted in your car now. The most batteries are located under the hood, but some can also be fitted in the trunk or under a seat. Check your repair manual or call your authorized dealer to get a fast answer.

Measure the size: Height, width and length. Also, check if you can find the “Ah” number on the battery.  Often you can fit a little larger battery then the battery fitted from factory, just measure and check if there is enough room.
I do not recommend to fit a smaller battery than the factory battery, because it may not have enough capacity and make strange problems with your car.

Q: How do I know if the battery fits my car?

A: If you are following one of the links to Amazon from this article, you can see a top bar at Amazon’s website where you can choose your car model. But to be 100% it fits. Always check the length, height, width and Ah before ordering a battery.
Also, check the battery terminals. They can have different sizes and be mirrored ( Terminals placed on different sides of the battery ).
Asian cars do often have smaller battery terminals than Europe/America.

Q: What are AGM battery and which are the benefits?

A: AGM is a shortening of Absorbent Glass Mat. The sulfuric acid is absorbed by a fine fibreglass mat, which is making the battery spill-proof.

The benefits of the AGM battery is Maintenance free ( Do not have to fill it ), Higher Performance, Faster Charging time, Vibrations resistance, stands up well to cold temperatures.

As you see, there are many benefits with an AGM battery. The less positive thing with an AGM battery is often that the price is higher and it’s more sensitive to over-charging.

Q: What are Ah and Peak A?

A: Ah is the measurements of the battery in ideal conditions, fully charged. Ah = Ampere Hour. It is the measurement of how many amperes it can put out in one hour full-charged.

Peak A is the measurement of how much Ampere the battery can put out under short times and high-loads.

Q: How to charge my battery the best way?

A: Slow charging with a smart car battery charger is the best way. If you have a smart car battery charger, it will handle it for you. If you want to learn more about this, check our article “How to charge a car battery the best way”. If you want to find the best car battery charger for your car, check out our review article: Car battery chargers.

Q: What is the expected lifetime of a battery?

A: Normally with a good quality battery, the lifetime is around 5 years. I have seen car batteries that have been working over 10 years. The most important part to higher your batteries lifetime is to not let it stand with a low amount of charge. Especially if you are living in a cold country. One night of low temperatures and low charge can kill the battery instantly.

Also, many low-cost batteries have lifetimes of around 2 years. If you are adding the cost of a car battery that has a lifetime of 10 years, the high priced battery is actually cheaper.

Q: My car is draining out the battery of my car, how to fix it?

A: This is a complex question and I’m going to write an article exactly of how to diagnose this later. The short answer is to check you DTC codes and check all door locks and switches. Door locks and switches are a very common problem with battery drainage. If the switch is faulty and the car thinks the door is open but it’s closed, it will lighten up lights and give power to other control units in your car. You can check your trouble codes with an OBD2 scanner, if you are interested in one, you can check it out here: OBD2 scanner tools

Q: Do I have to fill an AGM battery with battery-water?

A: No, The AGM battery is maintenance free and sealed. What you can do is to clean up the battery terminals once a year to make sure the terminals have a good connection. Maintenance charging a battery is always good and may give your car battery a longer lifetime.

Q: Can I safely jump start my old battery?

A: There is always a risk of jump-starting a car. New Jump starters do often have both wrong-polarity protection and overvoltage protection so the risk is very low if you are using the right tools. If you want to read more about jump starters you can check out our other article Battery Jump Starters.
Jump starting with jumper cables is a risk of wrong-polarity, but the overvoltage risk is not there.

Q: How to replace my battery?

A: First you have to locate your battery. The most common location is under the hood, but on some cars, the battery is located in the trunk or under a seat. Check your repair manual to locate your battery.
Make sure you have the Anti-theft radio code as it may be gone within the battery replacement. I do always connect a car battery charger under the battery replacement to prevent any data loss or radio code loss. To find a good car battery charger, check out our post: Best car battery chargers
Always lift the negative battery terminal first, to prevent any sparks ( Which can make the battery explode if it’s leaking ) and connect the positive first on the new battery. Always use protection glasses and gloves when you are replacing a car battery. I have seen one exploded when my colleague replaced a battery, so be very careful.

Q: How can I tell if my old battery is bad?

A: If you have tried to charge your battery several times, but it still sounds tired when you are trying to charge your battery, your battery is probably bad. There are several good battery testers on the market that will tell you if it’s time to replace your battery or not. One of those is the Cartman 12V Car Battery & Alternator Tester.

Q: Why should I remove the negative terminal first?

A: By removing the negative terminal first you will prevent any sparks. If you get a spark and your battery is leaking gas, the battery can explode and cause serious damage. Always use protection glasses and gloves when you are replacing a car battery. I have seen one exploded when my colleague replaced a battery, so be very careful.

Q: Is the temperature outside affecting the lifetime of a car battery?

A: Yes the temperature is a factor of the lifetime of the battery. Especially if your car battery is low in charge often. Car batteries in cold countries do often have a shorter lifetime than batteries in hot countries.
