Proscan CC566 Replacement Battery 7.4V 2900mAh Li-ion

Proscan CC566 Series — 7.4V Li-ion Replacement Battery

This is a 7.4V, 2900mAh Li-ion battery for the Proscan CC566 digital camcorder and related models including the CC577, CCHIT555, and CCHIT566. It replaces the original cell when charge retention has degraded to the point where recording sessions are cut short. Capacity figures come from the product data — 21.46Wh total energy.

• CC566 series compatibility: The CC566, CC577, CCHIT555, and CCHIT566 share the same battery bay dimensions, connector pinout, and 7.4V nominal voltage rail. A single cell covers all these models without any mechanical modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the bench and confirmed the BMS communicates correctly with the camcorder body — charge acceptance, cutoff voltage, and discharge curve all behaved within expected parameters for this voltage class.
• First-install charge cycle on the CC566: Run the first charge to full capacity inside the camcorder body or OEM charger before recording. Some Proscan camcorder BMS implementations require one complete in-body charge cycle before the battery-remaining indicator maps correctly to the new cell's discharge curve.

Why the CC566 displays a dead-battery icon on a partially charged replacement cell

The CC566's battery indicator reads state-of-charge by mapping voltage thresholds against a lookup table calibrated to the original cell's discharge curve. A new third-party cell can sit at 7.2V — well within usable range — while the camera interprets that as empty. This is a display calibration issue, not a cell defect. One full charge-discharge cycle inside the camcorder body re-aligns the indicator to the new cell's actual curve.

Battery percentage jumping erratically during recording on the CC566

During sustained video recording, the CC566 draws current from the sensor, processor, and LCD simultaneously, causing instantaneous voltage to drop faster than the indicator expects. The BMS reads that momentary sag as a lower state-of-charge and updates the display accordingly, which looks like the percentage is jumping. This is most visible when recording in high-resolution modes. Let the cell reach a resting voltage of 8.2–8.4V after a full charge before starting a long session to confirm full capacity is present.
