I have a relatively new (and recently tested) group 29 house battery with a RC rating of 210.
I can't make it through the night without the battery going dead.
Went out last weekend and boondocked at around 9pm. This was after a long day of driving and being on shore power the night before, so the house battery should have been fully charged.
We ran a few lights for a bit (I'd say less than 1 hour with maybe 2 lights), and used the water pump a few times (enough to rinse some dishes and flush the toilet).
After that it was nothing but the fridge. Got up about 3am to start up the furnace and the battery was too low to do so.
When I got home, I checked the drain on the battery.
Just parked with nothing on, there's about a 700 mA draw on the house battery due to the propane valve. Starting the fridge brings it up to about 1 Amp. lights seem to draw 1/2 an amp.
Even if I left a few lights on, there should only have been about a 2 Amp load for 6 hours....12 AH doesn't seem like much.
I had the battery tested at Interstate before I left and they said it was about 90% of ti's rating....but I'm not sure what rating they were talking about. Maybe the CCA rating?
Do I just need a new battery at this point? I've only had this one for about 2 years.
