I have 4 6V house batteries and they've been going bad after a couple years lately. I usually store my RV in a covered car port and leave it plugged into a 50amp service. Should I completely disconnect the house batteries and put them inside? Thanks

You MAY be over-charging them IF you still have the OE charger/converter, instead of one of the newer "smart chargers" that can vary the charge rate according to your battery's actual needs. I'm Assuming you are using "deep cycle" 6 volt batteries. They should last for more than 2 years when kept properly charged.

Store lead acid batteries fully charged. Fully charged means 14 to 18 hours on a modern high quality charger. Fully recharge before terminal voltage drops below 12.4 volts.

Get a cheap digital voltmeter. Monitor the voltage on the battery terminals periodically until you know how your system behaves.

13.2 volts is ideal for storing connected. Between 12.7 and 13.6 volts is good.
