Mitoya RL-480 3000-6000K Replacement Battery 7.4V 2000mAh

Mitoya RL-480 3000-6000 K — 7.4V Li-ion Replacement Battery

This is a 7.4V, 2000mAh Li-ion battery for the Mitoya RL-480 3000-6000 K camera. It replaces the original cell when capacity has dropped or the pack no longer holds a charge. Dimensions are 70.80 × 38.50 × 21.00mm — confirm against your existing battery before ordering.

• RL-480 3000-6000 K fit: The RL-480 series operates on a 7.4V nominal rail with a specific connector footprint. This cell matches that voltage requirement and physical envelope, so the pack seats correctly in the battery compartment without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, monitoring BMS cutoff at both the high-voltage ceiling and the low-voltage floor. The protection circuit tripped cleanly at the expected thresholds with no thermal event.
• First-install charge cycle: On first use, run one full charge cycle through the OEM charger or camera body before shooting. Some camera BMS systems need a complete charge cycle from inside the body to calibrate the battery-remaining indicator to the new cell's discharge curve.

Camera battery indicators map voltage thresholds to percentage steps. A new third-party cell can have a slightly different discharge curve than the original, so the camera reads the voltage and reports a lower level than the cell actually holds. This is a calibration mismatch, not a faulty battery. Run two or three full charge-discharge cycles through the camera body and the indicator will track more accurately against the real state of charge.

Battery percentage jumping erratically on the camera display

Erratic percentage readings happen when the camera's voltage-to-percentage lookup table doesn't align with the new cell's discharge curve. The camera samples terminal voltage at intervals and maps that reading to a bar or number — if the curve shape differs, the display skips steps or drops suddenly. This is most visible in the middle of the charge range, roughly 40–70%. Charge fully to 8.4V via the OEM charger, then discharge through normal shooting, and repeat two cycles to let the camera re-map the curve.
