Try not to bend, crease, deform, poke, or puncture the battery with your tool—a damaged battery is a potential fire hazard.

Insert your opening pick between the short edge of the battery and its housing, opposite the cable.

Slide your pick under the battery to slice the adhesive.

If the battery feels stuck, slide your pick around the perimeter to slice any remaining adhesive.

Pull up to peel the battery away from the adhesive.
