Lead Acid Battery - 2 Cells No Float
So I picked up a new (to me) rig from family last weekend. It had been sitting at the BIL's place for several years. He started it occasionally, but never kept it plugged in. 2 of the 3 group 29,...

You can attempt equalization but you have 3 Group 29 MARINE/deep cycle that's about 280/290 amp hours and about 71 usable before rapid aging sets in.
Go to a pair of GC-2 (about 220 Amp Hour) about the same price as a pair of Group 29's and you get 220 amp hours 110 usable before rapid aging sets in
And you can parallel a Group 29 with them (yes you can) in case a battery goes bad..
Hey J,
Long time. Thanks for weighing in.
Believe me, I've considered GC2s. They would always be my preference where height is a consideration along with even numbers. My old rig also had room for 3, so I went with 3 27s. I never considered 2 GC2s plus an additional 12V in parallel. Most intriguing idea.
I guess my stumbling blocks would be...
1. My 2-29s appear to be in excellent condition according to the SGs
2. I'm more concerned about max storage at the campground vs. life expectancy. Though again... your 12V hybrid parallel idea is something I hadn't considered before. I'm such a creature of symmetry, I would have that to overcome.
