Great guide and a great toolkit! I agree that pulling the adhesive tabs is the toughest part, but if you keep pulling from as close to the tape as you can (don’t extend the tape out far, keep your pull short) it can work. I was able to get one out, the other got stuck. I used the hair dryer to heat up the tape and card to pop the old battery out. I just need bigger glasses to see all that tiny stuff. Thank you iFixit!
