Pull the strip out slowly and steadily at a low angle. Give it plenty of time to stretch and un-stick from under the battery.

If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.

Repeat the process on all nine stretch-release adhesive strips.

If you removed all of the stretch-release adhesive, skip to this step. Otherwise, follow the next two steps for each battery cell with remaining adhesive.
