Installation Overview

Switch off the smartwatch completely before beginning the repair. Remove the watch strap where necessary and place the device on a clean and soft working surface.

Carefully release the installed battery from its position. Avoid bending, puncturing or applying excessive pressure to the battery cell.

Remove remaining adhesive and clean the installation area. Position the new battery in the same orientation as the previous battery and align the cable and connector correctly.

Secure the battery with suitable adhesive and reconnect all internal components. Soldering is normally not required, as the battery is connected through its integrated cable and connector.
