Mixing Batteries on Float-- Mex Test Update 2

Thanks Mex. So it is safe (even if not ideally efficient) to parallel them with each other and even with a bank of 6s?
I will run this another week, then I can try that recharge test if my equipment will suit. (Batts are in the garage at 35-40F if that makes any difference.)
I don't have a Killawatt gizmo like some people here have. I do have a Trimetric set to record amp hours. I can use a low amp charger to raise the battery voltage from whatever in the 12s to the mid 14s and note how many AH and the time that took (subject to the Trimetric's default allowance for heat loss)
Is that the idea? If so perhaps some scientist can translate that into that into KWh. Then what? What is good and bad wrt to the battery's 20hr rate capacity and the recharging amps used? (150AH for a single T-1275)
Now I have to read up on antimony poisoning of negative plates! Yipes --how long will they live with that going on? Use em or lose em time. :(
EDIT--Salvo, I don't have much luck with battery resistance testing based on past attempts. I can't organize my measurement timing right and get enough samples up and down like you explained is needed, to get anything but a very rough R. Might try again. I still have your instructions.
