I've had an optima yellow top battery sitting in my garage for about 6 months. I stuck it in the car and jumped it off. Drove around for about 15 minutes, turned the car off, and nothing. Still as dead as it was when I stuck it in. I've heard you cant use a normal battery charger for them, so is it trash?

Is there a way to "rejuvenate" a dry cell battery? - bosco50017:43:48 01/16/04
