Do not reuse the battery if it has been deformed or damaged, as doing so is a potential safety hazard. Replace it with a new battery.

Insert an opening pick into the battery well along one of the long edges of the battery.

Pry the battery upward to remove it from the battery well.

If the adhesive was successfully removed, the battery should come out very easily.

If the battery cannot be easily extracted due to unsuccessful removal of the stretch-release adhesive, apply 90% isopropyl alcohol as directed in the previous step.

Once you have allowed one minute for the alcohol to soften the adhesive, use an opening pick to pry up the battery from one of the long edges.

Do not bend the battery as you pull it out.
