Adgust these V #s by 0.04V for every 10 degrees colder temp
At 30 degrees a fully charged battery should show 12.588V
14.6 or 14.7 is fine for the charging system...
Have the battery checked with a load tester...

Blas,
I must be missing something:
Using the figures above and your formula, I get 12.48V at 30 deg F.
.04 x 5 (50 degrees colder than the 80 degree value)= .2V.
12.68V (the 80 degree full charge value) - .2V= 12.48V
How do you get 12.588V for the 30 degree value?
