Blaupunkt CC-664 6V Replacement Battery 2100mAh Ni-MH

Blaupunkt CC-664 / CC-684 / CC-695 / SC-625 — 6V Ni-MH Replacement Battery

This is a 6V 2100mAh Ni-MH replacement battery for the Blaupunkt CC-664, CC-684, CC-695, SC-625, and compatible compact camera models. It slots into the same battery compartment as the original cell and restores power to cameras that no longer hold a charge. Capacity is 2100mAh (12.6Wh), matching the original specification.

• Shared fit across CC-664 series: The CC-664, CC-684, CC-695, and SC-625 share the same battery bay dimensions and 6V supply rail. No connector modification or adapter is needed — the cell seats and contacts the same way the original does.
• Bench tested on actual hardware: We cycled this cell through the OEM charger and monitored BMS acceptance on each pass. The protection circuit tripped correctly at low-voltage cutoff and accepted a standard charge current without fault flags.
• First-cycle initialisation on Blaupunkt compact bodies: Run one full charge-discharge cycle inside the camera body or OEM charger before shooting. Some Blaupunkt compact bodies recalibrate the battery-remaining indicator only after seeing a complete cycle from the installed cell — skipping this step can cause the gauge to read inaccurately from the start.

Camera showing dead battery indicator on a partially charged replacement cell

Ni-MH cells have a flatter discharge curve than some camera firmware expects at startup. When the camera body measures open-circuit voltage on a new, partially charged cell, it can read that voltage as critically low and throw a dead battery warning before the cell has been cycled. The fix is to charge the cell fully before first use — not just partially — so the resting voltage sits at or above the threshold the camera checks on boot. Once the cell has completed one full charge cycle, the body reads it correctly on subsequent insertions.

Battery percentage jumping erratically during a shoot

Blaupunkt compact camera bodies map battery percentage using a voltage-threshold table tuned to the original cell's discharge curve. A replacement Ni-MH cell may discharge along a slightly different curve, causing the indicator to jump — say, from 60% to 20% without warning — even when actual charge remains. This is a display calibration issue, not a cell fault. Completing two to three full charge-discharge cycles allows the camera's internal tracking to settle against the new cell's actual curve. After conditioning, percentage readouts stabilise.
