Thanks All. Lots of good information here.
I started checking battery water and connections tonight. All of the cells are full, batteries are all the same type, contrary to my previous belief, and I have 4 of 6 battery terminal connections that were loose. I've been testing my fridge in the batteries and it had been almost an hour now my batteries are still at 12.1V and they haven't been on a charge since Saturday afternoon when we got back from our trip. So it looks like my batteries are in good shape.
Total of 330ah between the 3 wet cell size 27 batteries. Figure at the most right now, I will get 6 hours before the gen need to start and charge the batteries.
