The 24 hour pulse "Recondition" session on a Vector charger does not raise battery voltage. So that is not "charging."
It is meant to be a way to desulfate. I have used this and am not sure it works. I do see that after a session of Recondition, you can get the battery to a slightly higher "full" than before, so I have used alternating Recondition sessions and high voltage charging sessions to "recover" batts when they got stuck at a "full" that was too low. (Back when I had those 27s that were so difficult to recover. Don't need to do that with 6s) It may be that just taking a day off between high voltage sessions would work the same, but I never tested for that.
Meanwhile, there is something called "pulse charging" which I suppose does raise battery voltage. I guess this would be like when an MPPT solar controller goes into Absorption and uses PWM. That is charging with rising battery voltage.
