Replacement Battery for Garmin Fenix 7S

The KingSener 361-00145-00 is a lithium-ion cell rated at 226mAh and 3.87V. It matches the original part number 361-00145-00 for the Garmin Fenix 7S Multisport GPS Smartwatch. The unit ships new with a yellow finish and cells produced in China.

Direct Swap for Worn Original Cell

This battery replaces the factory pack when runtime has dropped noticeably. The jump is worth it if the watch no longer holds a full day of GPS tracking or if the original cell has swollen. No soldering is required because the connector matches the stock layout.

Suits Owners Needing a Like-for-Like Refresh

Buyers who want a simple, same-capacity refresh will find this cell fits the purpose. It is not for users who need extended capacity beyond the stock 226mAh rating or who require a different voltage platform.

Questions about this item

Does the 361-00145-00 fit the Garmin Fenix 7S case without modification?

Yes — the 361-00145-00 is built to the original dimensions for the Fenix 7S, so it seats directly in the watch cavity with no adapter or trimming required.

What is the correct way to install the 361-00145-00, and which step do people skip?

Remove the rear cover, disconnect the old cell, connect the new 3.87 V 226 mAh pack observing the polarity markers, then reseal the cover — the step most often missed is pressing the connector fully home before snapping the case shut.

When will the 361-00145-00 need replacing, and what indicates it?

Replace the 361-00145-00 when the Fenix 7S shows noticeably shorter run time between charges or fails to hold a full charge overnight — typical service life is one to two years of daily cycling.
