Very Low OCV on Full Batts???
I've been seeing lower than usual resting ocv this winter, compared to last. Figured it was either wear and tear, too high a charging voltage, or a parasitic draw. So I tried throwing a lower vol...

Thanks, guys.
Yes, I do have temp compensated charts for abs and float (courtesy of P.T.) and an SG correction table.
The higher voltages seemed to be causing the ocv to drop, like back in the fall, so I lowered things back down... of course, if it is one bad cell, that may have been the real problem all along.
Could one bad cell pull down the overall voltage readings without actually depleting the bank?
Regarding cold SG readings, if it reads say 1.290, that may only really be say 1.270, and so not as full as it appears to be? IOW, if my SG's are usually in the 1.280 range, when cold they should read higher than that? Or do the readings show the same on the hydrometer, and I have to add or subtract from the usual readings?
And if one cell is bad, wouldn't it show in the SG readings, or can the stronger cells pull the weak cell's SG up a little?
Thanks!
