PapaGo F210 Dashcam Compatible Battery 3.7V 450mAh Li-Polymer

PapaGo F210 — 3.7V Li-Polymer Replacement Battery

This is a 3.7V 450mAh Li-Polymer internal battery for the PapaGo F210 dash camera. It replaces the original cell when the dashcam stops holding a charge between drives or fails to start recording on ignition. Dimensions are 35.30 × 25.50 × 5.60mm — measure your existing cell before installing.

• F210 internal cell: The F210 uses a small Li-Polymer cell to bridge power between ignition cycles and to run parking mode when the engine is off. This replacement matches the original voltage rail and physical footprint that the dashcam's BMS expects.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS accepted the cell without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• First-cycle calibration after install: After installing a new internal cell, complete one full drive cycle — engine on, full charge, engine off — before relying on parking mode. The dashcam's power management needs one complete cycle against the new cell to calibrate parking mode duration accurately.

Why the F210 loses parking mode recording after a battery swap

Parking mode on the F210 draws directly from the internal cell once the ignition cuts. A new cell starts with an incomplete charge history, so the dashcam's firmware underestimates available capacity for the first few cycles. This shows up as parking mode ending earlier than expected — not a faulty cell, just an uncalibrated one. After two or three full charge cycles, parking mode duration stabilises.

A degraded internal battery can sag below the F210's minimum operating voltage mid-write, cutting power before the file closes properly. The result is a corrupt or zero-byte file rather than a clean recording. This is most common during parking mode when the cell is already partially discharged. Installing a fresh cell and allowing a full charge cycle restores the stable 3.7V the write buffer needs to close files cleanly.
