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...

SG is higher in the cold. With the fluid more dense due to lower volume, the bobber floats higher.
There is a correction table for that somewhere how much to add or subtract from the observed reading. The correction may vary a little by battery spec per brand but here is Trojan's (that 14.6 in this one may have recently been increased to 14.8 but the SG correction would be the same)

Note the temp vs voltage too--it says crank up the charger's voltage by x amount for a cold temp.
PS, I guess you don't want to know about daffodils just now! :)
