Winter battery storage class c chateau
In previous years my 1988 Ford motorhome was stored outside. I kept it plugged in and in the spring both batteries were still charged and I had no problem starting the engine.
This past winter my 2008 chateau class c was plugged in as I have done in the past.
Went out today and found the auxiliary battery was charged but the chassis battery was dead. Charged it up and then I could start the engine.
It would seem that the chassis battery does not accept power thru the auxiliary battery while plugged in. Is this correct?
If so do I have to remove the chassis battery and bring inside in the winter?
Can anyone answer this question?
