Hi Don.
I am also in forklift battery recon businss in Korea. The quality issue of a battery is related to understanding of the indice such as CCA, RC ,Volt or Specific Gravity. We know that volt or SG indice is not sufficient for judging the quality of a battery. We are using RC value as a standard for judging it. RC( reserve capacity) concept is very helpful in offer of warraty. We are using RC check method instead of Volt or SG check before and after recons.
In our case individualized cell of 2volt is connected to each computer. Conventional recon machine is using just one current 48volt or 36volt by serial connection. We connect each cell to each computer. The computer tells exactly every cell's state after discharge. After recon process, we know for sure how good the cell is and how good the battery in total is. I think this kind of new battery checksing system is needed. You may see more vids on Youtube under title, "forklift battery reconditioning"-individual cell treatment system.
