How to Choose the Best Car Battery Tester?

There are somewhere between oodles and scads of car battery testers in the marketplace. At first glance, most of them look remarkably similar. How do you pick from a field this large?

Here are a few points of differentiation and features to consider in a car battery tester.


Not all batteries are manufactured equally. Is yours a Maintenance-free, Gel, Absorbed Glass Mat, etc.? It’s important to know that your battery is definitely a compatible type together with your charger.

Look under your hood and find what you’ve got. Then check the manufacturer’s specifications before you make a buy decision.

2,Type of Tester

Different testers check different aspects of your battery’s performance. Which kind you choose will be dictated by your unique requirements, or how interested you are in DIY under the hood.

3,Load Tester

A charger with a battery load test feature contains a large resistor. By engaging the resistor, the tester takes on a similar electric load as the starter engine would while cranking. The tester can thus determine if the battery has the ability to start the car.

Performing a similar test on a working vehicle can diagnose the condition of the alternator, and inform you  if it’s still able to charge the battery.

4,Data Output You Require

Analog battery tester

With an analog display, you won’t get as exact a reading as with a digital. You will, nevertheless, get yourself a very clear idea of if the battery or system is performing within an acceptable range or not really.

This is because of the conveniently color-coded zones the needle passes through. They aren’t always  readable in low light, However, they do provide a large amount of information at a glance.

Degital battery tester

A digital tester offers you a very clear and precise result each time you check. You’ll know the exact reading without guessing or estimating, because of very low levels of charge. Also, they are readable under low light circumstances.

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

Even dead batteries can be dangerous even though they are no more holding any charge. A battery leak may be just like 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 whenever a spark is created near the terminal when the batteries are charging because of the gas. In the worst case, the battery could even explode which may be even more dangerous.

It is highly advised never smoke close to a battery especially during its charging. Keeping in mind the fact that explosions are rather rare during working on vehicles, having a battery blow up is nonetheless dangerous as batteries contain acidity. Acid is certainly not skin friendly so it’s smart to put on safety goggles, gloves, and a long-sleeve shirt. The acid should be properly included, but by no means tip the battery over or keep it the wrong way up, and become very careful if the casing is cracked.


Car batteries are usually quite accurate but with so many devices out there of several 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 isn’t a loss to buy and keep a car battery tester with you, in accordance to your requirements and budget. One will definitely come into use.
