Question
We recently had to replace both the engine and coach batteries on our RV. There is a button on the door for battery use or store. What is that button supposed to be on? We’re newbies to the big RV.

Welcome to the wonderful world of RVing! This switch is commonly called the Battery Disconnect Switch and is designed to disconnect your house batteries while being stored.
Pushing it to the Storage side is like taking off the battery cable. It ensures that if you have left a light on in a compartment or anything inside, it will not drain your house batteries. Some RV manufacturers connect the LP Leak Detector directly to the battery bypassing the disconnect, so you may still have a draw even with the switch on Storage.
To find out if this is the case with your rig, get a 12-volt test light, push the switch to Storage, then disconnect the negative terminal on one of the batteries. Touch the probe to the post and the alligator clip to the cable. If the light comes on, you have a draw.
Safe travels,

I have an 2024 Coleman Lantern and I’m wanting to know what is my battery controlling? What is the purpose of my battery if it shows I have 3/4 battery life, but nothing is working?
Make this simpler. If we are going to use only the solar powered battery is this key off or on. What else needs done the power is full nothing is running. We r sitting in the dark.
Love all the info
My battery disconnect switch worked fine last fall. Just plugged in the battery for the first time this year. Batteries fine because it ran the RV. But the switch won't come on.
When my generator is running and I open the door the generator shuts down. Should that happen.
