Let me suggest your Harris batteries are garbage and likely bad. Go to Walmart and buy 2 grp 27 max marine. Or, if you got deep pockets buy a couple Trojan's. Harris won't warranty the batteries because they say it is Thor's fault for having shabby chargers on board. I think their batteries just plain suck and they are squirming out of warranty. You are not alone in this scheme, we all have been suckered.

They will not run my Residential Fridge for more than 5 Hours. Can anything be suggested as to what can improve the longevity of these Batteries?
