Title
Apple Watch - Series 8 Battery Replacement
Introduction
Use this guide to replace a worn-out or dead battery in your Apple Watch Series 8.
***Note: The battery replacement procedure for the 41 mm Series 8 Apple Watch differs slightly from the 45 mm version.*** This guide shows how to replace the battery for both sizes.
Before you begin, make sure you have the appropriate replacement battery for your watch.
If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]]. For your safety, ***discharge your battery below 25%*** before disassembling your device. This reduces the risk of fire if the battery is accidentally damaged during the repair.
This guide shows the procedure on the cellular/LTE version of the watch, but the GPS-only version is similar.
You’ll need ***replacement adhesive*** to reattach components when reassembling the device.
