Nikon EN-EL23 Coolpix P600 Replacement Battery 3.8V 1400mAh

NiKon Coolpix P600 / P900 Series — 3.8V Li-ion Replacement Battery (EN-EL23)

This is a 3.8V, 1400mAh Li-ion replacement for the NiKon EN-EL23 battery cell. It fits the Coolpix P600, P610, P610s, and P900 — a family of bridge cameras that share the same battery bay and connector. Capacity figure is taken directly from product data: 1400mAh / 5.32Wh.

• Coolpix P-series bridge camera fit: The P600 through P900 line uses the same EN-EL23 form factor across all models — identical cell dimensions (47.00 × 34.70 × 10.35mm), the same three-contact connector, and a shared BMS voltage rail at 3.8V nominal. One cell covers the full range listed above.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a P900 body. The BMS accepted the cell without rejection flags, fuel gauge registered normally on the status display, and the camera completed full charge cycles through the OEM in-body charging circuit without thermal events.
• First-cycle initialisation on P-series bodies: Slot the new cell in and run one complete charge cycle through the camera body before a full shoot. The Coolpix P-series BMS maps its battery-remaining indicator to a discharge profile it learns on that first cycle — skipping this step can cause the percentage display to behave erratically from the start.

Flash recycling lag on the P900 at low cell charge

The P900's built-in flash draws a large capacitor recharge current after each shot. When cell voltage sags below roughly 3.5V — typical in the final 15–20% of any Li-ion discharge — the capacitor takes noticeably longer to reach full charge. This shows up as a delayed ready indicator between flashes, not as a fault. It is not a cell defect; it is how capacitor recharge current behaves at low cell voltage. Swap in a freshly charged cell and the recycle lag disappears immediately.

Battery percentage jumping around mid-shoot on a new cell

The Coolpix P-series fuel gauge maps percentage to a voltage-threshold curve calibrated against the original EN-EL23 discharge profile. A new replacement cell — even one at spec — can map slightly differently on the first few cycles, causing the percentage to jump or drop unexpectedly mid-shoot. This is a display calibration issue, not a capacity problem. Run two to three full charge-discharge cycles through the camera body and the gauge will track accurately against the new cell's actual discharge curve.
