I have Heart Freedom 15 inverter in 1999 Diplomat. When shore electric is hooked up, The batteries show dead. after driving for several hours, the inside remote shows the batteries dead. The built in charger-converter doesn't seem to be working. The hydrometer shows recharge, just below good. All 24 cells show the same (4_6v) none dead.
I know, kind of confusing.
Thanks,
