I have never really figured out why the use/store switch even exists because there is still a drain on the batteries!!!
If you were plugged in and switch was in the use position your batteries should be charged, need to check your charger output.
On our Axis the use/store switch only connects or disconnects the house batteries from the DC distribution panel. While this is typical for RV's it may not always be the case.
With our current set up and the use/store switch in store there is still a 0.1 amp draw on the house batteries 24/7. About half that is our solar system electronics. I also disable the Trombetta isolation between the cranking and house batteries to insure there is no draw that way.
