Does the battery voltage increase again when you remove the load?

No the voltage stayed the same removing the load.
The battery was down today slightly more at 85% @ 12.60v.
12.6 volts is about right for a fully charged battery that has rested
for a day or so.

12.6 volts sounds about right to me, but voltage is not a very accurate
indicator of charge for lead acid batteries. Cell electrolyte specific
gravity is a pretty good charge indicator ONCE the ACTUAL full charge
specific gravity is known for that one particular cell. (hopefully all the
cells are within a few points of each other....... what is the rule of
thumb...... 20 points difference?)
