Super Nova Electrical question

[Billynchrisnpa]

I just wanted to see if someone could give me some insight about the house batteries. I turned my disconnect switch off the last time I was in the RV about a month ago. I turned it on today and found the batteries were dead. Does anyone know what would drain the house batteries down when the switch is turned off? I plan on install a trickle charge as I have seen everyone else doing in past topics. Still learning about the RV.

With your disco switch off there should not be any parasite drains on the battery. However, temperature, humidity, age, and the time the batteries sit can have unwanted results. If I know my rig is gonna sit for a while I remove the house batteries and keep them in the garage on a maintenance charger. Happy trails.

Thanks for the post, I will have to do the same. The truck only sat for a month, between extreme temps and battery condition, may caused the issue.
