Cameron Sino Battery for Fenix 5S Plus 361-00096-00 150mAh 3.7V

Replacement Battery for Fenix 5S Plus

This Cameron Sino lithium polymer battery replaces the original power cell in Garmin Fenix 5S and Fenix 5S Plus watches. It delivers a capacity of 150mAh at 3.7V, matching the factory specifications for the part number 361-00096-00. The pack includes a fully decoded chip that communicates with the watch exactly like the original component. ISO9001, RoHS and CE certifications confirm baseline safety and quality compliance.

Practical Limits of Lithium Polymer Chemistry

The cell stores 0.56Wh of energy, which is typical for compact wearable batteries. Lithium polymer chemistry offers high energy density in a thin profile but degrades gradually with each charge cycle. A new unit reaches its rated capacity after two or three full charge and discharge cycles. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are built into the pack to limit damage from abnormal electrical conditions.

Compatibility Checks Before Ordering

Verify that your watch model is either Fenix 5S or Fenix 5S Plus and that the original battery carries part number 361-00096-00. The connector must align with the device socket; misalignment prevents proper contact and can damage the flex cable. Avoid charging the installed battery with low-quality third-party adapters, as unstable voltage reduces overall service life. Installation requires opening the sealed case, which affects the original water resistance rating.
