The problem is the adhesive does serve a purpose (mainly vibration/keeping the battery in place). Depends on how much you travel with it and the design overall (I’m not familiar with the steam deck but looking at the ifixit it appears ribbons are fixed to it so having the battery bounce around could be a problem)

That said you can buy those pull tab strips and could probably use them here. I hate those things but why not? Better than what was there, I guess. Especially bc the off brand ones can be fairly weak adhesive
