5mv/cell/degreeC
Theoretically my mppt solar controller is supposed to adjust the Absorb and Float set points by -5mv/cell/degreeC against a 25C standard. I have a 12V bank of 4 GC2s. So that is 6 cells? or 30mv/...

Hint:
I found linkage between voltage and resistor error in my DMMs. Therefore I now periodically verify with an ultra precision 5ppm calibration resistor. And I have no idea why this works :)
Heh, if this thing gets to the point where I can't re-calibrate it any more, I would have a hard time figuring out which resistor to swap out. And Rogue's website is no longer with us, so no help there.
Besides, my soldering skills aren't what they used to be. So, a new toy, rather, mppt controller would be what happens.:)
