Introduction
Use this guide to replace a worn-out battery in your Apple Watch Series 2.
Note: If your battery is swollen, take appropriate precautions.
What you need
-
-
Before starting repairs, take your watch off the charger and power it down.
-
-
-
Prepare an iOpener (or grab a hair dryer or heat gun) and heat the face of the watch until it's slightly too hot to touch.
-
Leave the iOpener on the watch for at least a minute to fully heat the screen and soften the adhesive holding it to the case.
-
-
-
Place the edge of a curved blade into the thin gap between the display and the outer case. Start at the short side of the display, closest to the digital crown.
-
Press firmly straight down into the gap.
-
Once inserted, tilt the blade to pry the display open slightly.
-
-
-
-
Once you've opened a small gap with the curved blade, remove the blade and insert the thinner edge of an opening tool into the gap.
-
Push the opening tool into the gap, using your thumb as a pivot to lift the display open a bit farther.
-
-
-
Insert an opening pick under the display and carefully separate the Force Touch gasket from the display.
-
Slide the pick around the display to separate the adhesive between the Force Touch gasket and the display.
-
-
-
Use a Y000 driver to remove the Tri-point screw securing the metal battery connector cover.
-
Remove the cover.
-
-
-
Disconnect the battery by prying its connector straight up with the edge of a pry tool.
-
Bend the connector up slightly to make sure it does not make contact by accident.
-
-
-
With the battery connector out of the way, insert the tip of a pry tool under the battery connector plate, which is part of the battery.
-
Lift the battery connector plate up and out of its recess.
-
-
-
Use scissors to cut one of your opening picks to about the width of the battery. Try not to leave any sharp corners.
-
Insert the modified pick between the edge of the battery and the case, on the side opposite the digital crown.
-
Use constant, steady pressure to slowly pry the battery up, separating it from the adhesive securing it to the system board.

-
Remove the battery.
-
If needed, try re-using the existing adhesive to secure the battery. Alternatively, try a small piece of double-sided tape such as Tesa 61395, or a dab of liquid adhesive such as E6000.
