I was worried when I did the same upgrade, but made sure to write down several post it notes in my workspace to quadruple check. I took it out before I even started to unscrew the case, but my heart did still skip a beat and there was a mini moment of panic right before I was going to pop the case open… checked again enough tho I knew I had already removed it.

I was more worried about stripping the screws… just make sure you use the right screwdriver and don’t try to force it. Had zero problems - most difficult part was getting the foil sticker off and wiggling the batter connector from the mainboard - it’s in there at kind of a weird angle and is very tight, so just shimmy it gently back and forth and it will eventually dislodge itself.
