I have the double battery in my car and I have probably a CTEK problem.
My car is parked since yesterday without driving. My fridge was running, and this morning I saw my main battery was at 12V and my auxiliary at 12.80V.
The trickle charging of the main battery through the auxiliary battery doesn't seem to work.
I checked the warning lights, and according to the manual it means the auxiliary battery is too hot. But, the car didn't drive, the ambient temperature is 18°, and the battery doesn't feel hot.
Anyone any idea?
(CTEK 250 installed, but not solar panels connected)
