The Ford Barn - View Single Post - Optima battery that will not hold a charge

Iwas working on my roadster and left the key on overnight. Killed the optima. put a very slow charger on it and it took in excess of two days to revive it. (less than two year old Optima.) A few weeks later it was dead again, key on, cleaned up the pop-out and now when I turn it off, it is really off and the optima is working great. I am running 6V possitive ground w/alternator. It now recharges normally while driving and seems to do so quicker than the lead acid battery did.
