Which battery tester is the best?

The best battery tester will depend on the type of battery that you need to test. The best way to find out which particular tester will work for your needs is to figure out what kind of battery it is and then research a few different models in order to see how they compare. You can ask a professional or consult the user manual for your particular model for the best possible instruction.

What does it mean if the battery fails the test?

If the battery has not passed its load test, remove any unnecessary devices from it and wait ten minutes before measuring again. If, at this stage, you still don't have a good reading on your state-of-charge, then for safety reasons, we recommend replacing that old drained-out battery with one capable of holding more CCAs. This will ensure longer lasting power in all aspects.


Car batteries are best when fully charged and ready to go. No one wants a car that dies on them during some random moment or just won't even start at all, which is why investing in something as useful as this battery tester is important for those who use cars regularly.
