Thx Mort. It seems like 27 minutes on a 10 amp charger will not charge up a dead battery. I do like how you explained the math behind charging time. if I,have zero amps in the battery, like I left the key in the ignition for a week. Don't I have to get a bunch of amps back in the battery. doesn't a ten amp charge stuff 10 amps in a battery per hour? Sc
