We have a new 2014 Bighorn 5er that has two 12V Excide deep cycle Marine type #27 batteries. This unit has been plugged into shore power since we took delivery in April either at home or at F/H campgrounds. This past weekend we did four nights of dry camping without any type of H/U.
Night #1 power usage consisted of: one hour with two LED lights on for reading, running of Dometic 12 CF double wide fridge, LPG detector operating, LPG furnace ran through three cycles due to outside temperature at 50 F, water pump ran for three toilet flushes. In the morning the RV battery indicator panel read 1/3 full. I ran the Honda generator for 6 hours throughout the day and evening and tested the batteries ½ hour after turning off the generator. Volt meter reading was at 15.2 and 15.1 for the two batteries.
Night #2 power usage consisted of: NO LED lights (used Coleman lanterns for reading), running the fridge on LPG, running the LPG detector, furnace NOT used, water pump used for two flushes, but would not operate after 4 A.M., at which time the battery indicator panel showed the batteries were empty. I used generator again to fully charge both batteries to 14.7 and 14.8 volts.
Night #3 and #4 usage was the same as night #2, again with the generator used each day to recharge the batteries. The batteries went FLAT from 9 P.M at night to 4 A.M in the morning which is 7 hours. No lights or other appliances were being used.
Is it possible that the Dometic fridge running on LPG is the cause of the batteries going flat? Should I have the dealer replace both batteries? Is this nornal for two 12V batteries to run flat in 7 hours with running of fridge on LPG only?
Thanks for your thoughts on what I should do.
