12v Golf Cart Battery Question
Sorry, don't have enough internet access at the moment to do a proper search, so I thought I'd ask here :) Talking with a local guy today who seems to know his stuff. He gave me a tip that the loc...

Trying out the used T-1275s. First cut at an AH figure is not very accurate, but came out to 243 out of 300 or 81%. They hold up under load ok about the same as a pair of 6s running the MW on the big inverter at 110a draw .
I was having trouble with my jury rigged set-up for consistent results and also the black stuff comes up and messes with the SG readings at times, which makes picking your SOC by SG tricky.
So now I will run the trailer for a few days as I have been all summer with the four 6s only now with the two 12s in their place as wired up for real, and see if I can figure out what I really have here using the Trimetric a lot.
I think equalizing them would be ruinous with all that black stuff coming up even on a regular charge up into the 14s, so I am thinking of the Vector's pulse type 24hr "reconditioning" which does not raise battery voltage might be the answer.
If they are at 243AH as calculated first cut, then that would be 81% of 300AH rated, so the guy at the golf car place would be correct in his mysterious way of measuring capacity by time of golf car run. Guess they must have some sort of clue :)
No idea what I will do with the whole collection of batteries if these 12s are any good for a year or two to go. I think in summer now, we could do it on two 6s and solar. Winter we go four batts and no solar ok, but use the gen/charger as required. Not sure where having six batts fits into the scheme :) At least they all fit in the front bay of the trailer! Just need more wire links.
Balancing two big 12s and four 6s as a bank of three or four 12s is an interesting exercise, the solution to which I leave to PT !! :)
