I use an old transformer type 12 volt wall power supply. Rated 800ma. Balances out to 13.4 volts maintenance charge level. Cost me a pair of 3/8" ring terminals, some shrink tubing and solder. Most any half pound transformer-type "12 volt" 800ma power supply will end up doing the same with a single group 24 - 31 battery.
They can NOT break! Well, if you shove 180 volts into one while it's connected to a battery it may eventually overheat. But it's the most reliable single battery maintenance system I can think of. A BATTERY TENDER grade maintenance charger cannot possibly have this degree of INHERENT protection. BUT, exercising a periodic topping charge is still essential when storing batteries for four months or longer.
