I have a California Comfortline. I have two brand new AGM 70 Ah batteries, but they discharge to less than 50% in just 2-3 days even though I hardly use any electricity at all. (Only the refrigerator on level 3 and some lights and the control unit says -0,04A). The control unit says that the batteries are fully charged after driving for a about 1h.
If I turn on the engine with AC/car lights etc off the control unit says 14,2V 20Ah (Got about the same numbers with a multimeter.), but when I turn on the AC/ car lights etc it drops to 13,7V.
If I plug in the cable the leisure batteries gets 14,35V.
Is it possible that the leisure batteries are not fully charged due to too low Volt while driving even though the control unit says that they are 100% charged?
Or is there any other explanation?
