Exactly, these are new batteries so they would not be too bad, and yes a slow trickle charge after de sulfate should make it good as new.I have had batteries that were sulfated to the point they wouldn't take a charge. If they are at that point, the de sulfate cycle will take it to the point where it will take a charge. Then I start the charge cycle and the charge is pretty slow as the battery starts to accepts a charge. After some time the charge rate will go up. Because the high voltages used in the de sulfate cycle, you need to disconnect the battery and I reserve that process only for really dead batteries.
My mustang had about an hour drive home and the day after I got it home, it took a slow 5 hour charge to get it topped off. I am pretty sure it was a little sulfated but a long slow charge was able to reverse it.
