I recommend Graupner Ultramat 12

Thanks - that looks like the ticket. I had thought about RC model
chargers, but thought there might be issues using one on a lead acid
battery for prolonged trickle charging. The specs at the Graupner
website: http://shop.graupner.de/webuerp/servlet/AI?ARTN=6412.67 seem
to indicate this will not be a problem.
