RCA CC-8251 Replacement Battery 7.4V 2200mAh Li-ion

RCA CC-8251 / PRO-V730 / PRO-V742 — 7.4V Li-ion Replacement Battery

This is a 7.4V, 2200mAh (16.28Wh) lithium-ion battery for the RCA CC-8251, PRO-V730, and PRO-V742 digital cameras. It replaces the original pack when capacity has dropped and the camera no longer holds a charge through a full recording session. Voltage and cell count match the original spec exactly.

• CC-8251, PRO-V730, PRO-V742 compatibility: These three models share the same 7.4V two-cell configuration, physical footprint, and connector orientation. The BMS in each camera expects the same charge termination voltage, so the pack seats and communicates correctly across all three.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the bench, monitoring BMS cutoff behaviour at both the low-voltage threshold and full-charge termination point. Cell balancing held within spec across repeated cycles with no false protection trips.
• First-use cycle on RCA cameras: After fitting this pack, record a full clip and play it back before charging — the camera's charge indicator calibrates to the new cell voltage curve during active use, not during standby. Skipping this step can cause the indicator to read low even when the pack has significant capacity remaining.

Why the CC-8251 cuts out during video recording with a new battery

The CC-8251 draws a higher sustained current during 1080p video than during still shooting. If the BMS detects a voltage sag below its protection threshold — common when a degraded or cold cell can't sustain the load — it trips and shuts the camera off mid-recording. A new pack with healthy internal resistance handles this sustained draw without triggering the cutoff. If the shutdown persists with a new pack, check that the battery contacts on the camera body are clean and making full contact — even a thin film of oxidation raises contact resistance enough to cause a false trip.

Camera shows a flashing battery icon immediately after inserting a new pack

This happens when the new pack arrives at a storage charge level — typically around 3.7–3.8V per cell — and the camera's voltage-threshold indicator hasn't yet mapped it as a full pack. The flashing icon is the camera misreading cell state, not a fault with the battery. Place the pack on charge immediately after fitting it for the first time and allow it to reach full charge termination before use. Once the camera has seen a complete charge cycle, the indicator recalibrates and reads correctly from that point forward.
