Compatible replacement battery

This lithium-polymer pack replaces the original 361-00108-00 cell in Garmin Vivoactive 3 smartwatches, covering model numbers 010-01769-01, 010-01769-09, 010-01769-11 and 010-01769-21. It delivers 3.7V nominal voltage with a 3.85V peak and a rated capacity of 160mAh for 0.6Wh of energy. The cell is designed as a direct swap for the factory battery.

Build and installation

The battery uses a lithium-polymer chemistry housed in a compact pack that fits the watch chassis. Free installation tools are included in the package so the swap can be performed without sourcing separate screwdrivers or pry tools. No soldering is required; the connector mates with the existing board. The unit is supplied new and carries a one-year replacement warranty from MPF Products.

Pre-installation checks

Verify that the watch model number printed on the case back matches one of the four listed variants before opening the device. Confirm the original battery part number is 361-00108-00 to ensure the connector and form factor align. Ensure you are comfortable disassembling a sealed smartwatch, as the process involves removing screws and lifting adhesive. Buyers who need a higher-capacity cell or a different voltage should look elsewhere.
