Mitoya RL-480 Replacement Battery 7.4V 2600mAh Li-ion

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

This is a 7.4V, 2600mAh (19.24Wh) Li-ion replacement battery for the Mitoya RL-480 3000-6000 K camera. It slots into the same battery compartment as the original cell and powers the camera through photo and video shooting sessions. No OEM part number is published for this model.

• RL-480 3000-6000 K fit: The RL-480 series runs a single 7.4V Li-ion cell with a fixed connector footprint. This replacement matches that voltage rail and physical form factor — 70.80 × 38.50 × 23.20 mm — so it seats and locks without modification.
• Bench tested on actual hardware: We cycled this cell through the camera body using the OEM charger path. The BMS accepted the cell on first install, reported charge state correctly, and held voltage above the camera's low-battery cutoff through sustained video capture.
• First-install charge cycle on the RL-480: Some camera BMS systems need one full charge-from-empty cycle completed inside the camera body before the battery-remaining indicator maps correctly to the new cell's discharge curve. Run the first charge in-body, not in a third-party external charger, to get accurate percentage readings from the start.

Dead battery indicator on the RL-480 with a partially charged replacement cell

Camera battery indicators use voltage thresholds calibrated against the original cell's discharge curve. A new third-party cell can have a slightly different mid-discharge voltage profile, causing the camera to misread state of charge and flag low or dead battery while usable capacity remains. This is a display mapping issue, not a faulty cell. One full charge-to-discharge cycle in-body resets the threshold reference and the indicator corrects itself.

Battery percentage jumping erratically during shooting

Erratic percentage jumps happen when the camera's fuel-gauge algorithm samples voltage during high-draw moments — flash recharge, continuous autofocus bursts, or image stabilisation pulses — and misinterprets the transient sag as a genuine capacity drop. The displayed percentage then snaps back once load drops. This is not a cell defect. If jumps persist beyond the first charge cycle, confirm the cell is fully charged to 8.40V before shooting — a partially charged cell amplifies the sag signature and makes the reading worse.
