Cameron Sino Femix 6s Pro Venu 361-00086-12 170mAh 3.8V standard battery

Replacement Battery for Femix 6s Pro and Venu

This 170mAh nickel-zinc cell matches the original 361-00086-12 specification for Garmin Femix 6s Pro and Venu wearables. It delivers 3.8 volts and 0.65 watt-hours in a 28.60 x 19.60 x 3.30 mm form factor. The pack carries ISO9001, RoHS and CE certification. It suits owners who need a direct drop-in replacement for a depleted original.

Steady Discharge in Daily Wear

The nickel-zinc chemistry maintains a stable voltage curve across the full 170mAh capacity during typical smartwatch workloads such as GPS tracking, heart-rate monitoring and notification handling. There is no sharp voltage sag after a short burst, so the device remains functional until the cell is nearly exhausted. Users who require sustained high-current pulses beyond the rated capacity should consider a different chemistry.

Low Self-Discharge and Minimal Heat

Nickel-zinc cells exhibit very low self-discharge, so the battery holds its charge during periods of infrequent use. Normal operation generates negligible heat inside the sealed watch case, and the chemistry does not produce audible noise. The 3.8 volt nominal voltage aligns with the device power-management expectations, avoiding extra current draw from voltage conversion.
