Proscan CC566 Replacement Battery 7.4V 2000mAh Li-ion

Proscan CC566 / CC577 / CCHIT566 Series — 7.4V Li-ion Replacement Battery

This 7.4V, 2000mAh Li-ion cell replaces the original battery in Proscan compact digital cameras including the CC566, CC577, CCHIT555, and CCHIT566. It fits the same battery bay footprint at 70.30 × 38.00 × 20.10mm. Voltage and capacity match the OEM spec exactly as listed in the product data.

• Cross-model compatibility — CC566, CC577, CCHIT555, CCHIT566 and more: These Proscan camera models share the same battery bay geometry, voltage rail, and connector orientation, which is why one cell covers the full lineup. The BMS threshold on each body reads the same charge profile.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, confirming BMS acceptance, stable voltage delivery across the discharge curve, and correct cutoff behaviour at the low-voltage threshold. No cell left the bench without passing that sequence.
• First-cycle initialisation on Proscan camera bodies: Run one complete charge cycle through the camera body or OEM charger before your first shoot. Some Proscan bodies need this cycle to map the new cell's discharge curve accurately — without it, the battery-remaining indicator may read erratically or show full then drop suddenly.

Flash recharge lag mid-shoot on a new replacement cell

The Proscan CC566's built-in flash capacitor draws a sharp recharge current spike after each shot. A new cell that hasn't completed a full initialisation cycle may deliver that spike at a slightly lower voltage than the camera expects, causing the ready indicator to lag. This is not a fault in the cell — it's the camera's capacitor-charge circuit responding to voltage sag during the first few cycles. After two or three full charge-discharge cycles, internal resistance drops and the lag clears. If it persists beyond three cycles, check that the battery contacts on the body are clean and seated at the correct depth.

Battery percentage jumping erratically on the Proscan display

This happens when the camera body's fuel-gauge mapping doesn't yet match the new cell's discharge curve. The original OEM cell trained the indicator over many cycles; a replacement cell starts with no history in the body's memory. The camera reads voltage checkpoints and converts them to percentage — if the curve shape differs slightly from the stored map, the display jumps. Perform one full charge to 8.40V via the OEM charger, then discharge fully in-camera through normal shooting, and the indicator will re-calibrate against the new curve.
