Replacement Battery for Fenix 6X

This nickel-zinc cell delivers 300mAh at 3.7V and matches the original 361-00126-00 part number. It is built to the same 36.00 x 24.80 x 4.00mm footprint and weighs 7.0g. The pack includes a fully decoded chip so the watch reports capacity correctly. ISO9001, RoHS and CE certifications back the manufacturing quality.

Build Quality and Daily Fit

The slim 4.00mm profile slides into the existing battery bay without forcing the case back. A pre-fitted connector aligns with the motherboard header, so no soldering or adapter cables are required. Over-charge, over-discharge, over-voltage and short-circuit protection circuits are integrated into the pack. Shock-absorbing foam in the retail box guards the cell during transit and storage.

Compatibility Check Before Ordering

Confirm the watch model is Fenix 6X, Fenix 6X Pro Solar or Tactix Delta Solar and that the original battery carries part number 361-00126-00. Verify the connector orientation matches the photos supplied with the listing. Plan for two or three full charge-discharge cycles before expecting maximum runtime. Avoid low-quality third-party chargers to preserve cycle life.

Questions about this item

What voltage does the 3.7 V nickel-zinc cell deliver to the Garmin Fenix 6X?

The cell is rated at 3.7 V and 300 mAh, matching the original 361-00126-00 specification for the Fenix 6X and Tactix Delta Solar.

Will the 36.00 × 24.80 × 4.00 mm pack fit inside the Fenix 6X case?

Yes, those are the exact dimensions of the original battery, so the replacement sits flush in the watch housing.

Which connector orientation avoids the common mis-alignment during installation?

Align the ribbon connector with the motherboard socket before pressing; the keyed plug only seats one way, and forcing it bent pins on early units.
