      Harvesting Cells

      If you prefer to harvest the cells, you have to remove the rubber (if any) around the cells and extract the cells as shown here. You'll have to cut and clean the Nickel interconnects using snips.

      Once the cells are out and clean you will have to test them using a charger like this.
