Rollei RL410B Actioncam 230 Compatible Battery 3.7V 1000mAh

Rollei Actioncam 230 / 400 Series — 3.7V Li-ion Replacement Battery (RL410B)

This is a 3.7V, 1000mAh Li-ion cell that replaces the Rollei RL410B battery. It fits the Actioncam 230, 240, 400, and 410 — all compact action cameras sharing the same battery bay and connector. Dimensions are 41.36 × 36.15 × 8.63 mm, matching the OEM form factor.

• Actioncam 230 / 240 / 400 / 410 compatibility: These four models use the same RL410B cell with identical connector pinout and voltage rail. The BMS handshake is consistent across the range, so one cell covers all four bodies without hardware modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the Actioncam platform. The BMS accepted the cell on first install, reported charge state accurately, and showed no cutoff anomalies during sustained 1080p recording loads.
• First-cycle calibration on Rollei action cameras: Run the first full charge inside the camera body using the OEM cable or charger — not an external Li-ion bay charger. Some Rollei BMS firmware maps the battery-remaining display against a calibration charge completed from within the camera, and skipping this step can cause percentage jumps throughout the cell's life.

Why the Actioncam 400 and 410 drain this cell faster than the 230 and 240

The 400 and 410 models support higher bitrate video modes and have more active image processing load than the 230 and 240. That additional processor draw pulls more current from the same 1000mAh cell, so shoot sessions are shorter on the higher-end bodies even with an identical battery. This is not a cell defect — it is the difference in platform draw. If you use this cell across multiple bodies, expect the 400 and 410 to call low-battery earlier than the 230 or 240 under equivalent recording conditions.

Battery percentage jumping erratically on the Actioncam display after fitting a new cell

This happens when the camera's BMS has not yet mapped its voltage-threshold table to the new cell's discharge curve. The original cell trains the indicator over hundreds of cycles; a fresh cell starts that process from zero. The erratic readout is a display calibration issue, not a fault with the cell itself. To resolve it, complete two full charge-to-discharge cycles entirely within the camera body — after the second cycle the percentage indicator typically stabilises and tracks accurately down to the 3.0V low-cell cutoff.
