I have 2011 Autotrail Arapaho. factory fitted solar panel (80w I think). Mostly camped on hook up to date but this weekend we went to a rally with no hook up. Within 24 hours started getting worried about the LBs as volts dropping, and we hardly used any lecci. Fridge & water heater on gas (but I did leave them on continuously), a few 12v lights for short while. Saturday was reasonably good day, quite a bit of sun but not great. Control panel told me solar panel was generating 0.3 to 0.7 A and the LB capacity was 95% AH. Battery was 12.7 v but within short while was dropping to 10.4v. I had to run the engine for 30 mins and went to bed. In the morning the heater had switched itself off as volts had dropped below 10.5v and the weekend continued this way. Charged Lb by running engine but they wouldn't hold for more than 6 hours or so. Not impressed by what I get from Solar panel but I don't feel batteries are holding the charge. So do I need to ditch them and replace?
