For me, removing the battery was a battle because I couldn’t get a grip on the adhesive bar at the end of the battery. I just used some “gentle” persuasion and a little heat to make the battery give up. Once it was lifted a bit I could get the adhesive strips to stretch in the classic wa. The battery was worse for the wear.
