Garmin Virb 360 Replacement Battery 3.8V 1100mAh

Garmin Virb 360 — 3.8V Li-Polymer Replacement Battery (010-12521-40)

This 3.8V, 1100mAh lithium-polymer cell replaces the original battery in the Garmin Virb 360 action camera. The Virb 360 is a spherical 360-degree camera that stitches dual-lens footage in-body, placing continuous load on both the processor and sensor array. OEM part numbers 010-12521-40, 360-00106-00, and 361-00106-00 all cross-reference to this cell.

• Virb 360 compatibility: The Virb 360 uses a compact Li-Polymer pouch cell rated at 3.8V nominal. The camera's BMS monitors cell voltage and temperature over a single-wire communication line. Any replacement cell must match the original footprint (43.46 × 26.40 × 14.15mm) to seat correctly in the battery bay without flex pressure on the pouch.
• Bench tested on actual hardware: We cycled this cell through the Virb 360 body under sustained 360-degree 5.7K recording load. The BMS accepted the cell without a rejection flag, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no forced shutdown below the safe floor.
• First-use charge cycle on the Virb 360: Insert the new cell and run one full charge cycle through the camera body via USB before your first shoot. The Virb 360 BMS calibrates its battery-remaining display against the cell's discharge curve during this first cycle — skipping it can cause the indicator to read inaccurately from the first use.

Why the Virb 360 draws harder than a standard action camera

The Virb 360 runs two image sensors and a real-time stitching processor simultaneously during recording. That combined draw is higher than single-lens action cameras of the same era. On top of that, GPS logging and ANT+ sensor broadcasting run in parallel when those features are active. Each active feature stack adds to the continuous current draw from the 1100mAh cell.

Battery percentage jumping or freezing on the Virb 360 display

This happens when the camera's BMS hasn't mapped the new cell's discharge curve yet. The indicator is voltage-threshold based — if the curve of the replacement cell differs slightly from the aged original, the display can skip or stall at certain percentages. Run one full discharge-to-cutoff cycle followed by a full charge inside the camera body. After that cycle, the BMS recalibrates its threshold map and the percentage readout stabilises.
