I believe this is a misunderstanding. The charge voltage needs to increase by a particular amount for every degree below 77 F (25 c).
It needs to be decrease by that same number for every degree above 77 f (25 c).lawrosa wrote:
Yes I know to raise or lower the volts .028 per cell for every 10 degrees above or below 80f. This equates to .336 volts for 12 cells.
Its every 10 degrees in ambient temperature not 1 degree..At least thats what I read from all the battery manufactures sites pretty much..
