The Best Car Battery Testers & Analyzers 2020 – Review & Buyer’s Guide

In Reviews by Magnus SellénLeave a Comment

Car batteries are one of the important components which power all the electrical components, your car’s headlights, stereo, and your car itself.

The starter motor draws power from the battery and the spark plugs get the power from the same source. That means without the battery, your car wouldn’t simply start at all. But that is to say, like all the things in the world, batteries can go back after some time of use.

Although car batteries are rechargeable and made to last for many years before needing replacement, they lose their charge to a considerable amount and that’s when they need to be replaced. But there are now many tools and equipment which can help you determine the status of your battery and how much life it has got in it.

Often times you get stranded in the middle of nowhere with no mechanics nearby, all due to a bad battery. If you’ve had known that your battery was losing its charge, you would have changed it before using your car again right?

Well, with the help of battery testers, you can do just that and the best thing is you can do it all by yourself with little precautions and safety measures.

Down below you will find the best car battery testers & analyzers you can buy for your car so that you no longer need to find yourself in a difficult situation and you can prevent it way beforehand in case of bad batteries.

A car battery is a simple yet a core component of a car as it’s needed to power the car and all its electrical parts like the lights and even the engine. It is basically power in bulk. Keeping in mind that battery itself is an electrical item, it can prove to be dangerous if not handled with care. Extreme precaution is must when dealing with batteries whether acid ones or any other type of batteries of high volts.

Even dead batteries can be dangerous even though they are no longer holding any charge. A battery leak may be just as lethal. Certain batteries give off hydrogen gas while its charging and the hydrogen gas tends to be highly flammable. This is why often there’s a fire when a spark is created near the terminal when the batteries are charging because of the gas. In the worst case, the battery may even explode which can be even more dangerous.

It is highly advised to not smoke near a battery especially during its charging. Keeping in mind the fact that explosions are rather rare during operating on vehicles, having a battery blow up is nonetheless dangerous as batteries contain acid. Acid is definitely not skin friendly so it’s wise to put on safety goggles, gloves, and a long-sleeve shirt. The acid should be properly contained, but by no means tip the battery over or keep it the wrong way up, and be very cautious if the casing is cracked.


Car batteries are usually quite accurate but with so many units out there of many different brands, each one has some benefit over the other. Some provide more features at a higher price while other brands keep the features and price at a basic level. Nonetheless, it is not a loss to buy and keep a battery tester with you, according to your needs and budget. One will definitely come into use.
