Blaupunkt CC-R900H Compatible Battery 7.4V 4400mAh

Blaupunkt CC-R900H / ERC884 / F9 — 7.4V Li-ion Replacement Battery

This 7.4V 4400mAh Li-ion battery fits the Blaupunkt CC-R900H, ERC884, and F9 camcorders. It matches the original cell voltage and capacity, restoring full recording and playback function. Capacity is 4400mAh (32.56Wh) — taken from product data, not estimated.

• CC-R900H, ERC884, and F9 compatibility: These three Blaupunkt camcorder models share the same battery bay dimensions, connector pinout, and 7.4V operating rail — a single cell platform covers all three without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a camcorder body. The BMS accepted the cell, held voltage above the low-battery cutoff through sustained recording, and flagged correctly when the cell approached depletion.
• First-install charge tip for camcorders: Charge this cell fully inside the camera body or OEM charger before your first recording session. Some Blaupunkt BMS firmware maps battery-remaining display thresholds against the first full charge cycle — skipping this step can cause the indicator to read inaccurately from the start.

Why the CC-R900H shows a dead-battery warning on a freshly installed replacement cell

Blaupunkt camcorders read the battery state by sampling cell voltage at rest before the BMS initialises a new charge cycle. A replacement cell shipped in a partial-charge state can present a resting voltage the firmware interprets as critically low — triggering a false low-battery or dead-cell alert. This is not a fault with the cell. Connect to the OEM charger or charge via the camera body until the indicator shows full, then power on. The warning clears once the BMS has mapped the cell across a complete charge cycle.

Battery percentage jumping erratically mid-recording

The CC-R900H estimates remaining capacity by comparing real-time voltage against a discharge curve stored in firmware — a curve calibrated to the original cell's chemistry profile. A replacement cell with a slightly different discharge curve can cause the percentage indicator to skip non-linearly, reading 60%, then 80%, then 40% within minutes. The cell itself is delivering stable voltage; the display logic is misreading it. Run one full discharge-to-cutoff cycle followed by a full charge inside the camera body — this allows the BMS to recalibrate its voltage-threshold mapping to 3.0V per cell at depletion.
