I'm not sure long-term charging removes sulfation. Possibly cyclical
charge-discharge cycles does. If you could crank for 60 seconds and the
battery was still showing 12.57 V, I think you are done (other than
recharging it from that test.)

Thanks for the reply Jon. I think I'll try a few charge/discharge
cycles.
