Replacement Battery for Garmin Instinct Solar

This Cameron Sino lithium-polymer cell replaces the original battery in Garmin Instinct Solar STD-810G watches. It matches the factory specifications of 340mAh capacity and 3.87V voltage. The pack measures 35.00 x 14.00 x 3.00 mm and carries ISO9001, RoHS and CE certifications. A fully decoded chip ensures the watch recognises it exactly like the original unit.

When to Swap the Original Cell

Install this battery when the original no longer holds a usable charge through a typical day of tracking. The jump is worth it if the watch powers off unexpectedly or the battery gauge drops rapidly during outdoor activities. A new cell restores the full 1.32Wh energy rating the device was designed for. Expect optimal runtime after two or three complete charge and discharge cycles.

Checks Before Ordering

Verify the watch model is Instinct Solar STD-810G and confirm the original battery part number is 361-00136-10, 361-00164-00 or 361-00164-10. Ensure you are comfortable opening the case and seating the small connector correctly. Avoid low-quality third-party chargers after installation, as they can reduce the new cell's lifespan. The package includes protective foam for safe transit.

Questions about this item

What are the exact dimensions of the STD-810G battery pack so I know it fits my Garmin Instinct Solar?

The battery pack measures 35.00 x 14.00 x 3.00 mm, matching the original Garmin 361-00136-10, 361-00164-00 and 361-00164-10 specifications.

Which connector orientation do I need to watch when installing the 340mAh lithium polymer cell?

Align the flexible ribbon connector exactly as the original sat; the decoded chip only communicates when the pins seat fully, so press until the latch clicks.

After how many charge cycles should I expect to replace the 3.87V 1.32Wh battery in my Instinct Solar?

Lithium polymer cells typically last 2–3 years of daily use; replace when runtime falls below half of the original 340mAh capacity.
