How Many Amp Hours are in a 12 Volt Battery?

To figure out how many amp hours are in the battery you need to test it by charging it and seeing how long it takes to completely discharge. For example if a 12 volt battery at 8 amps takes 20 hours to discharge then it would have 160 amp hours. You just need to multiply the amps by how many hours the battery lasts. To calculate amps you divide voltage by resistance.
