Do battery checkers work?

Oh, absolutely! Battery checkers can be super helpful when it comes to figuring out if your battery is still in good shape or not. I actually use a battery checker myself because I'm really into RC cars, and I need to make sure my LiPo batteries are still holding a charge.

For example, when I'm getting ready to take my RC car out for a spin, I'll use a battery checker to make sure my LiPo battery is fully charged and ready to go. It's super simple - I just plug the battery checker into the battery, and it tells me the voltage of each individual cell in the battery. If any of the cells have a significantly lower voltage than the others, that's a sign that the battery might not be in great shape anymore.

But here's the thing: while battery checkers can give you a good idea of the health of your battery, they're not perfect. Sometimes, a battery might look like it's in good condition according to the battery checker, but there could still be underlying issues that the checker can't detect.

So, while a battery checker can be a useful tool, it's important to use other methods of checking your battery as well. For example, I always make sure to visually inspect my LiPo batteries for any signs of swelling or damage, and I also keep track of how many charge cycles I've put them through.
