When "recovering" beat up batteries with my VEC1093DBD, I have found that Equalizing (raises voltage) works up to a point, then SG stops rising. I then run a few Reconditioning cycles (voltage does not rise--some pulsing thing happens for 24 hrs a go) and then run another Equalize. This time the SG gets up a bit higher than last time.
I have done this many times now on various beat up batteries and am convinced that the Reconditioning "loosens up" things so the recovery using Equalize can advance some more. YMMV.
