Confusion there maybe. I did resurrect two T-1275s (12v, 150AH each) from about 85% good as new to about 90% good as new, but they still have uneven SGs per cell, even though all cells are way higher than when I first got them.
I should check and update those SGs since returning from the last camping trip where they got another couple of deep cycles and a recovery at home last week.
The SGs are not the same in each battery, so they are perhaps not ideal to parallel, but I parallel them while camping and separate them on individual Float chargers at home. Mex says they have evil interactions as they are, and will hurt my 6s if paralleled with them. I assume from that they could be evil to each other too.
I really like those T-1275s, evil or not. :)
