NiKon Coolpix 600 Replacement Battery 2.4V 1800mAh

NiKon Coolpix 600 — 2.4V Ni-MH 1800mAh Replacement Battery

This is a 2.4V Ni-MH 1800mAh replacement battery for the NiKon Coolpix 600 digital camera. It slots into the original battery compartment and restores power to the camera's core systems. Capacity is rated at 1800mAh (4.32Wh), matching the original cell specification.

• Coolpix 600 platform fit: The Coolpix 600 uses a compact Ni-MH cell at 2.4V to run the image sensor, lens drive, and onboard processing. This cell matches that voltage rail and physical footprint — 50.00 x 29.80 x 16.50mm — so no adapter or modification is needed.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the bench. The BMS accepted the cell without rejection flags, and voltage recovery after draw was consistent across multiple cycles.
• First charge cycle on the Coolpix 600: Charge this cell fully inside the camera body or OEM charger before your first shoot. Some Coolpix BMS firmware maps the battery-remaining indicator based on a completed charge cycle — skipping this step can cause the indicator to read inaccurately from the start.

Flash recycling slowdown on the Coolpix 600 with a new cell

The Coolpix 600's flash capacitor pulls a sharp recharge current after each shot. A Ni-MH cell that hasn't completed its first full charge cycle may show voltage sag during this recharge burst. This causes the flash to take noticeably longer to ready itself between frames. Run one full charge-discharge cycle through the camera body first — flash recycling behaviour typically normalises after that.

Battery percentage jumping erratically on the Coolpix 600 display

The Coolpix 600 maps its battery indicator to specific voltage thresholds tuned to the original cell's discharge curve. A replacement Ni-MH cell can discharge along a slightly different curve, causing the indicator to skip between readings or drop suddenly. This is a display calibration issue, not a cell fault. Perform one full charge cycle inside the camera body and the indicator will recalibrate to the new cell's actual voltage profile.
