I own a 2014 Airstream. I have 3 solar panels. I've recently moved from S.Calif to N.Calif With the constant sunshine in S.Calif my two batteries were always charged up. Now it seems to be the opposite. When I turn off the main battery switch to the trailer, the only current which constitutes a small draw on the batteries is the propane leak detector and the digital clock in the entertainment unit. I'm curious if physically disconnecting the batteries would help leave a partial charge in them ? Now I've removed both batteries and have them on my workbench in my garage, connected to a battery charger, trying to recharge them fully; but like I said above, after a camping trip, should I physically disconnect them ?
