      Harvesting Cells

      If you prefer to harvest the cells, you have to remove the case, extract the cells (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.


      Note that these are reclaimed packs, so the actual cell voltage you receive may be lower than the label shows. We make no guarantees that all cells will be usable. These items are sold for DIY and Second Life purposes. Sold as-is. No refunds. Buyer is responsible for proper cell recycling/disposal.


      Listings that are “untested” as sold as-is and cannot be returned, exchanged or refunded. These items are sold for DIY and Second Life purposes. Even when sold as “new”, “NOS”, or “like-new”, they may be in less than perfect condition. Buyer is responsible for proper cell recycling/disposal.

      If you buy a product from us and then realize you don't have, or don't want to acquire, the tool(s) or information needed to make our product(s) work for your specific build, this does not constitute valid grounds for replacements, exchanges or refunds. You are responsible for doing your due diligence before making any purchases.
