Progress Report on Used T-1275s
People asked to keep them informed how it went after I got these second hand golf car batts in case they had a chance to get some. -I have been nursing and camping with doing some 50-90s, a pair of...

I hope your T-1275s work out well. As seen above, I have mine working properly after some initial nursing.
I get 12.1v for the 50% mark confirmed by the Trimetric AH count and my notion of how many AH is "full" depending on the temperature and from my last load test where I got 270AH for the pair. It has checked out a couple of times now while camping, so I am confident in the numbers. I don't think I have their resting voltages when full---I have them on a Float once they are charged up or else they are down some while camping.
I treat them as though they are the same as my 6s for charging them and they do seem to need the Equalize (15.7v) shot after being brought to Full at 14.8v with the VEC1093DBD. I'd be lost without that charger. You can do it with a manual charger if you can stay there and monitor it. The VEC you can let it do E it by itself so handy for letting it run overnight or while away from the house.
I use a $5 hydrometer, but it is the long glass tube with a bobber in it, not one of the fat plastic stupid things I can never get to work right. It is accurate enough for my purposes.
Lately I have them banked with my two pair of 6s in a three-12s in parallel configuration with the loads and charging going to the outside ends. I know about using buss bars and links to balance three 12s better, but haven't got that far yet. Plus I keep changing my set-up so the wiring is always messy. :) I might go back to a four and two split when going back to using solar this Spring.
