Funny I should see this first thing after coming back from 5 days aboard. Funny, because; my gen set batt went kaput first try I did to start gen set. Found the batt read 10.0 on multi meter. Sooo - I charged it over knight with 1 amp trickle charger. Read about 12.3 in morning with charger on its terminals. Soon as I took charger off batt.... the 12.3 reading dropped very quickly as I watched. Hit starter on gen set and got about 2 revolutions before dead again. Purchased new starter batt, installed it and went merrily on with boating. My gen set alternator charges its battery.

PS: Don't use dual purpose batt, use starter batt only for this... lasts much longer, for internal batt reasons!
