I am very leery of any charger that says,automatic,floater,maintainer,or smart charger.One little tickle from a thunderstorm and the sensitive parts seem to become solid circuits.Anything that has little lights to tell state of charge make me nervous.Same thing with chargers that say they will shut off when battery is fully charged.They may do it when new,but once they've been dropped they seem to just keep charging.I've had two real serious problems with the Deltran maintainers.The company got back to me a few months after I contacted them,they said if somebody tries to start the car with the maintainer still hooked up the sensors could get fried.One had a meltdown sitting on the top of a Wheelhorse tractor,the other one I had hooked up to four batteries in a Brockway.Batteries were in parelell,and I left the maintainer hooked up to them for a week.I walked into the shop one morning and there were pieces of battery all over the place.Turns out the thing never shut off like it was supposed to.Is there a reason you feel you need a maintainer? If you have a drain,you have something that needs to be fixed.
