Hi, Im currently working on a MBP 13" Unibody with a bloated battery. When attempting to remove it, I found myself stripping the leftmost screw like butter. As the battery expanded, it actually broke free of the mount (see pictures), and I’m worried if I take a dremel to it the battery may puncture. https://prnt.sc/j3geu3 https://prnt.sc/j3gf8l Any ideas would be much appreciated. Thanks in advance, John

That plastic retainer screw hole has broken anyway. They do that a lot even on normal batteries as they are so weak, over tightening the screw will break the battery tab. Just take the battery out, then you will be able to get a pair of pliers on the screw to remove it. I use theses: Screw Extracting Pliers MacBook Pro 13" Unibody Late 2011 Battery Replacement
