Ken,
Yes I read that earlier. Because I am not sure what I have for a converter I am not leaving the batteries connected to the coach, even when the store/use switch is in the store position. I suspect that then batteries over charged because three of the twelve cells were very low on electrolyte after being left plugged in for a few months. Yes, I should have checked them more often. Also the batteries were boiling and too hot to touch. The sides were swollen on one, indicating that it had sulfated. I expect to replace the engine battery sometime soon. I will replace it with a maintenance free battery.
