Even if the voltage reads fine the battery can still be bad. The only real way to know if a battery is good or not is to have it load tested. You can take it to AutoZone or AdvanceAuto and they can test it for you. I'm curious though, that voltage reading is actually low for what should be a fully charged battery. A fully charged battery should be somewhere close to 14.4volts.HEMI05RAM said:I replaced my stock battery with a Optima Yellow-Top. I had a newbie cashier so I didn't get charged the $8 core charge. Is there anything I can do to make it good again??? The DMM reads 12.6V.
Or just chunk it?
I would just leave it at one of the stores and leave. What are they going to do? Throw it away?lassenloop said:When I swapped the battery in my Jeep for dual red-tops I had a hell of a time getting rid of my battery. None of the parts stores wanted it, b/c I bought my batteries online. The county recycling center didn't want it either. Just so happened that one of the guys at the recycling center needed a battery and mine was still good.
