Begin by removing all the old adhesive, glass, and any other debris from all adhesion surfaces.

You can pull the adhesive off with tweezers or your fingers, roll it up on the tip of a spudger with a roll-and-pull motion, or scrape it off with the flat end of a spudger.

After removing most of the adhesive, scrape with the tip of a spudger to get small bits of adhesive out of tight spaces.

When working around a battery, be extremely careful not to accidentally puncture or bend the battery.
