Absolutely -- USE/STORE must be in USE for the batteries to charge. If you have it in STORE with shore power applied or the generator running, you will have a false sense of security because EVERYTHING in the RV will work. That's because the converter is providing AC and DC power to all the electrical circuits in the RV.

What won't happen is that no DC current will be routed to the batteries to keep them charged. Whether you are driving down the road, have shore power connected and on, or your generator is running -- the USE/STORE must be in USE for the batteries to stay charged.

Very few dealers ever tell new owners this during the PDI -- probably because even they don't understand what charges the batteries, under what conditions, and when.
