Power99 has an excellent video on youtube on the teardown.
Take ur time don't rush. I tore mine apart & didn't break anything...whew!
T5 or T6 screwdriver
Tape/magnetic to hold the 22 screws.
Flat rounded tip wedge for GENTLY prying the bezel and back off. I used 3 wedges.
Mine turned out not to b the battery but the internal charging port. That was extremely tricky z4 me!
