Went to autozone today to test out my ets mini battery and we think its bad. We checked it at 600 amps and at 750 amps and the machine said its bad. Was it tested at the right amps?

 

ireally don't trust those tests.
i bought a battery once from pep boys. used it in the car for a week- disconnected the battery and it died so i brought it back and they said it was a bad battery

 

i work at o'reilly auto, my tested said my battery was bad...! I installed it for ****s n giggles and its been working fine ever since..

 

From my experience, the battery tests only work if you have a fully charged battery. So if you hook it up to a battery tender for a few days and then test it, if it tests bad then it would be pretty accurate.
