Ohhh, I was forgetting about the affect the concentration of sulfate
and hydrogen ions would have on the Gibbs free energy of the reaction
(the voltage any battery produces is the change in gibbs free energy of
the reactions that take place divided by the amount of charge that has
to move for that much energy to be transferred). As you keep charging
above the resting SOC voltage, you should be producing more H+ and
SO42- ions, which will increase the Gibbs free energy of the reaction,
thereby increasing the voltage of the pack. Those hydrogen and sulfate
ions gradually recombine, bringing the gibbs free energy (and therefore
voltage) back down to what it should be.
Ok, I think I'm all set now....
Thanks,
Mike
