Re: Do I need a new battery?
said by Juggernaut:i agree, my comment was not intended to be a fix, only solution if the 1-2VDC change is bothersome with a normal battery, alternator and properly auto-idling engine.
Nope. Test first, then replace what needs replacing.
Healthy batteries should be at 12.6 V static, with lights on 12.2. Alternator should be charging at 13.2-13.8 V.
perhaps the OP's vehicle is not auto-idling properly with load on the engine ?
