How to remove battery with broken adhesive?

Hey guys, so my mi5's digitizer broke and I'm changing it. Anyway I got a problem: while trying to remove the battery both the adhesives broke even before I started pulling them out. Now I'm stuck with the battery glued to the device. I don't want to try to pull it out using tools since I had a bad experience in the past (almost made a hole in a battery), is there anyway I can do it without damaging it? (since it is also pretty new and I don't want to change it). Maybe heating it and using a suction cup could do?
