A question for those that store their coaches in the off season.
Do your AGM batteries stay charged for 3 or 4 months if they are disconnected tp prevent discharge from ghost loads?
Thanks in advance
Our spare AGM kept over 12.7 for over a year just sitting on the shelf. Check voltage every couple of months and charge if down more than a couple of tenths of a volt. Batteries sulfate at 12.3 volts.

Can we then put switches on the pos. side of both sets of batteries as an alternative to keeping the coach hooked up?
You'd want to put disconnects on the negative side.
