Fitbit charge teardown. It stopped working and was sent a new one so tore old one open...wondering if possible to replace battery (cant find a replacement) as the voltage is 0.
LSSP031420AB lipoly battery.
Remove all four T3 Torx screws. Then "pop" out the electronics by pressing in the reset hole and pushing out the side with a pin. Use your thumb and push it up towards the wrist band clip (top in this picture). The unit "slides" up and out.
To access the lipo, remove the two screws above the screen. Pull the circular vibrating motor out and pull out the board.
Image 3a) Two inner screws removed, case gently pried open.
Image 3b) Obverse, showing battery glued onto the circuit. Be careful when prying this up as it could pull off the other connectors.
