Jim, I maintain 6 12V batteries (RV and cars) with the "float charger" available from Harbor Freight. The float charger is not a battery charger per se, it keep the battery in a full state of charge and shuts off when that condition is achieved. The paper work with the float charger says you must start with a full charge and the float charger keeps the charge there. Additionally the paper says that these chargers are not to be used to recharge a battery... I guess a more correct name might a battery charge maintainer. I've found them to work very well and I especially like the stand by feature that shuts off when the charge is full thereby not keeping a charge going past a full state which tends to over charge and boil off the electrolyte. These units run about $12.00 each but are on sale for $4.99 plus there's a %20 discount coupon. As far as I know they're only available in 12V.
