So...if I have TWO batteries would I have 1000 Amp hrs. and last twice as long???Olbird wrote:Gary,
The dealer installs the battery so you will need to know the battery amps you have and use this calculation chart to determine battery drain.
I would guess that your residential refrigerator requires 700- 800 watts to run.

The LP 5500 Onan generator uses about .8 gal per hour on 1/2 load, and 1.1 gal per hour at full load, 7-8 hours on one 30# tank in the 3850RL.
Two batteries will charge at the same time, you may want to get a rapid stand alone charger to run off the generator, solar charger will be the best thing because that refrigerator is going to pull a 27 group 500 amp battery down in a few hours.
Would it be easier to get a small gas gen. (Honda 1000, 2000 or equal) and a separate charger? I'm thinking easier to take/go fill up a 5 gal. gas can that lug 30# LP bottles to get filled...?
