George do you mean lead acid is fully charged at 12.7 at 80f. I have one
rated for more but maybe 12.7 is the correct average, Nicads do peak at
1.32-1.35.



12.65 volts is 100%

Yep, but it is easier to just say 12.6-12.7
because of temperature compensation and many volt
meters (maybe most) are less than 1 percent
accurate for the readout.
