What's up with my coach batteries?
I purchased a 2015 Four Winds 31W... went on a couple trips and then had it at the dealer for 6 weeks fixing a bunch of problems we found... nothing major, mostly cosmetic.
It has two coach batteries (they say 27 series but are smaller Harris batteries... ) and an 1800w inverter... (residential fridge).
When I got it home, I plugged it in for 24 hours to charge, unplugged, hit the battery disconnect switch, and left it for 2 1/2 weeks.
So yesterday I went out to check on it, and the batteries were dead enough that they didn't show a reading at all when I turned on the inverter to look at the charge. I went to start the generator and had to start the car first... too dead to turn it over.
Ran the generator for two hours. At that point when I turned it on, the inverter reading said 12.2 ... still really low. So I plugged it into shore power overnight.
So then 18 hours later, I went out... and I could hear the batteries bubbling. Opened the cover to the compartment and one of the two batteries was warm, there was a little water around one of the two cover thingies, and it smelled a little bit, and my CO sensor was flashing and occasionally beeping.
I unplugged the shore power, turned on the inverter and it reads 12.4 .... so I turned it off, hit the battery disconnect, and opened vents and windows and left a message art the dealer.
Before they call me back... can anyone shed some light on what the issue might be? I didn't seem to have this problem before leaving it at the dealer... although it seemed early on that the batteries discharged pretty quickly (maybe 4 hours with fridge on).
Thanks for any info!
