Slide the battery out of the frame to remove it.

If any adhesive remains, clean it with a few drops of isopropyl alcohol and wipe it with a lint-free or microfiber cloth.

Before removing any adhesive liners from your new battery, place it in its recess to make sure it fits. Then, remove the adhesive liners and firmly press each cell into place.

If your battery doesn't come with adhesive, secure it with new stretch-release adhesive.

Alternatively, you may use strong double-sided tape such as Tesa Tape to secure the battery.
