Improving a "Used" Battery Can be Done
I got a used pair of Trojan T-1275s (150 AH each , 82lbs) that the previous owners (new and used golf car dealer) claimed were at about 86% as good as new before they put them on the pallet where they...

Thanks, Mex. It is not your usual RVing situation, but some Forum members wanted an update in case they raided a golf course for some used batts.
Another point of interest is that the combo of two 12v T-1275s and two 6v GC2-XHDs, have a voltage drop of about 0.7v when hitting them with a 100a draw, compared with the 1.0v drop when using four 6s.
PT is always on about 12v vs 6v for voltage drop, so this supports his story. Also it means that where with four 6s I can go to 50% SOC and stay above 11v inverter alarm, now with the 12v/6v combo I can maybe go down to 40% and still run those 100a draws--to be determined!
If so, then maybe I could run 40-80s instead of 50-90s in the winter and meet those two- hour Provincial Park gen time limits instead of that 2 3/4 hours it took today. (Although I can also split the bank and charge two with 100a and two with 40a if I don't care about the Trimetric, which can only do one or the other)
