So I somehow destroyed my battery within a year, it expanded and won't hold any charge. My shop said it either had a parasitic drain causing it to go dead and then it froze or the car overcharged the battery and destroyed it. there is no warranty with either type of damage. A voltmeter says it is charging at 14.62V, is this ok or too high?

what alternator you running? Cold weather, overcharging, hot weather, vibration.........can do that do a battery

oem alt

new oem or 90's oem????????

don't know i've only had the car since 2006 i haven't changed it

could be overcharging and a bad battery
