Optima Recharge
I have an Optima Yellow Top from 2007 that is holding a 13 plus volt charge. I have a Red Top from 2015 that was holding a good charge but is now down to 10.5 volts and will not charge higher. The Yellow one did this for a while but snapped back with a battery tender. I tried that with The Red top but no Dice.
Should I just give up on these buggers or does some have a magic bullet?
