I think a good charger makes a world of difference.

We overcharged several batteries to death using the chargers that came in the Kit of Parts many years ago. The Schumacher 2/4/6 amp Speed Chargers provided in recent years are much better; they correctly drop to a "charge maintenance" mode when the battery is fully charged. I've not heard any real complaints about the 3-bank RS3 that AndyMark sells, except that they don't have a state-of-charge "meter" and you can't force them to a lower charge rate when you aren't in a hurry.
