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 under the left side of the top edge of the battery.

If you encounter significant resistance at any point during this procedure, stop, apply a little more adhesive remover, and wait for it to soak in.

Slide the card side to side under the upper left battery cell to slice through the adhesive underneath.
