Is killing batteries three times too much?
I use a set of 6V golf cart batteries from Costco. The pair that is in my rig now is two years old and they only last a couple of nights before the low voltage alarm on my CPAP starts sounding. When t...

Mex, what do you do with a strong sister in the bunch?
My T-1275s' cells are all over the map, can't get them equalized with my equipment. Been like that for a year now and the batts work great despite the funny SGs.
Banking them with the four 6s over a long period on solar doesn't work though. The 6s get charged before the T-1275s do and then the 6s just sit there losing water. Another lesson learned. Anyway, two T-1275s from pos to neg posts best readings:
Batt 1- 12.75, 75, 95, 75, 75, 75
Batt 2- 12.80, 75, 70, 90, 85, 90
Doing attempted equalizings now and then, the same cells are always the ones stronger or weaker so it is consistent in that way.
I just keep using mine the way they are, and don't worry too much about it. I do like to do a 40% state of charge left in them, run kind of hard, leave the TV on and the lights so I lose at about 7 -9 amps an hour for a few hours before I top off charge them then equalize them. But like your T-1275's mine are all over the map, a 10 to 20 point spread on the weak sister and the Top Gun. They work fine, for camping, maybe not so much good for a golf cart.
