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,...

Old batteries. Get rid of them and try AGMs
Thanks 2oldman,
Yeah, I'm well versed in AGMs vs FWCs. AGMs have their place, but I got over 10 years out of my old group 27s and a 6300 series converter because they could be safely equalized... and the rig was always plugged into shore during storage.
And then only 10 years because the property owner stopped paying the power bill without letting me know. SG numbers were still beautiful just beforehand.
That said... my BIL did replace the Cat starting batteries with a pair of these babies. I won't know their condition until I can do a load test. A 500A load tester has been on my list for many years. Perhaps I'll take the plunge rather than driving the rig into the shop. Though I might be concerned that one of these monster batteries could blow the thing to smithereenies.
With the cranking power specs of these suckers, part of me wants to sell one off and utilize the storage space for a 4th GC2. Worst case... I could always start the Cat with a boost from the house bank.
(Brainstorming) OR... since it's an AGM... with low self discharge and no concern of spillage...
I could keep one of them in a separate compartment as a jumpstarter and just top it on occasion. I guess I could start with seeing how easily just one of those AGMs turns over the Cat with a multimeter monitoring things.
