There are several ways to maintain batteries, but what I do is fully charge both house and chassis batteries then disconnect them. They set for 3 months over the winter that way. During the camping season I do the same until I plan on going camping, then will plug MH into my 50 amp plug and charge several days with my old Mangntec converter charger and the refer cools at the same time. The HF maintainer charger will charge the chassis battery. I also have a B&D 40 amp charger that can equalize and desufate. I equalize every 3 mos or so and desulfate maybe twice a year. Batteries will be 10 years old this year and I dry camp 95 persent of the time. I think leaving the charger on continuously eats away at the lead plates quicker, you just don't want to let them sit too long in a discharged state or they will begin to sulfate.
We don't have a winter in California. Camping season is year round so I want to keep the motorhome ready to go whenever I am.
