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.

Remove the battery.

If the adhesive was successfully removed, the battery should fall out loosely.

If the battery cannot be easily removed, 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.
