Use this guide to replace a worn-out or dead battery in your Samsung Galaxy Watch Active.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your watch. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

You might need replacement adhesive to reattach the battery when reassembling the device.
