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,
