The house batteries in our new motorhome need to power a 2000w inverter and allow us to boondock for several days at a time. Against our better wishes, it cam furnished with a full size residential refrigerator that must be kept going while in the boonies. It came furnished with 4 6v Harris Professional Plus golf cart batteries. I think that the dealer let them discharge badly before the motorhome was sold to us. Anyway, time for new ones! After a little research and some prodding from a local dealer where we are having our warrantee work done, they are recommending 4 new Centennial CB6-250 GC2H sealed lead acid AGM Batteries. They seem pretty top notch when looking at the specs. 250 AH @20 Hr rate, reserve capacity of 570 min @25 amp draw. I can get them locally for $320 each + 30 core charge. Has anyone used these batteries or anything similar? Any thoughts? Thanks!!
I use a couple of these batteries ganged together in balanced-parallel in our RV ... if I could fit them, I'd use more. They're popular in the marine world, have a long warranty, and - unlike many AGM batteries - have a higher recommended float voltage of 13.6 volts - unlike the usual 13.2 volts of most liguid and AGM lead acid batteries. (I needed a higher float voltage AGM to exactly match the nominal voltage of our RV's converter):
