I’m sorry but at least in my case it was absolutely impossible to pry the battery away gently. There was such an amount of glue that I almost gave up. The battery bent like !&&* and two spudgers broke. i didn’t use any heat. And I think it would be important to actually show te reassembly because at least I don’t have any idea how much and what sort of glue should be used at any given point. I used B-7000 because that was my best guess.
