This is not an answer, but an additional question. I have three 12 volt house batteries, their location demands "no maintenance" My charging system is a magnum 2000 modified sign wave inverter/converter. Also, my engine batteries are a pair of interstate batteries that appear to be "no maintenance" but have a very poor life cycle. My usage is limited to 5 month a year, with the coach sitting the other seven.
