Compatible Garmin Forerunner Models

This replacement cell fits the Garmin Forerunner 205, 305 and 305i. It matches the original 361-00026-00 part number and restores power to those specific GPS watches. Owners of other Garmin devices or non-Garmin wearables should look elsewhere.

Pre-Installation Checks

Verify that your watch is one of the three models listed above and that the existing cell carries the 361-00026-00 code. Confirm the watch accepts a 3.7 V lithium-ion pack measuring 38.90 x 34.25 x 5.50 mm. Ensure you have the tools and skill to open the case without damaging the water seal.

Sustained Use Behaviour

The 700 mAh capacity delivers 2.59 Wh of energy for multi-hour training sessions. Lithium-ion chemistry maintains a steady voltage during continuous GPS tracking rather than sagging after a short burst. The 60 g cell adds minimal mass during extended wear.
