Compatible Replacement for Fenix 5X Series

This replacement cell is built for the Fenix 5X Plus, Fenix 5X Running and Fenix 5X watches. It matches the original part number 361-00098-00 and fits the 27.4 x 25.26 x 5.0mm cavity. The pack weighs 31.8g and supplies 3.8V nominal voltage. Buyers needing a different form factor or a higher capacity cell cannot use this unit.

Sustained Output and Protection

The lithium cell delivers 410mAh capacity and 1.56Wh energy rating under continuous load. Integrated circuitry guards against overcharge, over discharge, over voltage and short circuit events during daily wear. Certificates include ISO9001, RoHS, CE, UN38.3 and MSDS for safety compliance. The pack is not suited for devices that demand a larger energy reserve.

Simple Swap Installation

Remove the case back, disconnect the old cell and connect the new one using the original connector. No soldering or special tools are required beyond a small screwdriver set. The tight internal space means careful alignment avoids pinching the flex cable. Users who skip the model check often order the wrong variant for their specific watch.

Questions about this item

Will the 3.8 V 500 mAh cell run warm if I wear the watch all day?

The lithium cell is rated at 3.8 V and 500 mAh with overcharge, over-discharge and short-circuit protection, so it stays cool during normal daily use.

Do I need any tools to swap the 361-00098-00 battery in my Fenix 5X Plus?

The replacement pack measures 27.4 x 25.26 x 5.0 mm and weighs 31.8 g; it fits the watch cavity directly, so only a small screwdriver for the case back is required.

Will this 410 mAh / 1.56 Wh unit work alongside the original charging cradle I already own?

Yes, the cell carries the same 3.8 V nominal voltage and 361-00098-00 part number, so the existing cradle charges it normally.
