Battery Testers & Analyzers Information

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 the battery itself is an electrical item, it can prove to be dangerous if not handled with care. Extreme precaution is a 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 it’s 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.
