Take care not to puncture or bend the battery with your tools—a punctured or bent battery may leak dangerous chemicals or cause a thermal event.

Slide a plastic card underneath the far left battery cell group to slice through the adhesive holding it to the case.

If you encounter significant resistance at any point during this procedure, pause and apply more adhesive remover. Wait for it to soak into the adhesive, and try again.

Wiggle the card from side to side as you insert it under the battery cells to fully separate all adhesive holding them in place.

Leave the plastic card temporarily underneath the cell to prevent it from re-adhering while you continue.
