Nikon EN-EL23 Coolpix P600 Compatible Battery 3.8V 1700mAh

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

This is a 3.8V, 1700mAh Li-ion cell built to the EN-EL23 specification. It fits the NiKon Coolpix P600, P610, P610s, and P900 bridge cameras. Slot it in where the original EN-EL23 sat — same footprint at 47.00 × 34.70 × 10.35mm.

• P600 / P610 / P900 platform compatibility: All four models share the EN-EL23 form factor and the same 3.8V voltage rail. The connector pinout and BMS handshake protocol are identical across the lineup, so one cell covers the full group.
• Bench tested on actual hardware: We cycled this cell through a P900 body. The BMS accepted the cell without a reject flag, reported state-of-charge correctly after one full charge cycle, and held voltage above the low-battery cutoff threshold through sustained burst shooting with the 60x zoom extended.
• First-install charge protocol for the P600 / P900: Run the first charge inside the camera body via the supplied USB cable rather than an external charger. The Coolpix BMS maps its battery-remaining display to a discharge curve sampled during the first in-body charge — skipping this step causes the indicator to read inaccurately for several cycles.

Flash recycling slowing down on a fresh EN-EL23 cell

The Coolpix P600 and P900 flash capacitor pulls a sharp recharge current spike after each pop. A new cell that hasn't completed its first full charge cycle delivers slightly lower peak current than a fully conditioned cell, which stretches capacitor recharge time. This shows up as a longer-than-expected wait between flash shots in the first few outings. After two or three full discharge-and-charge cycles, peak current delivery normalises and recycling speed returns to spec.

Battery percentage jumping erratically on the Coolpix display

The Coolpix indicator maps voltage thresholds to percentage segments calibrated against the discharge curve of the OEM cell. A replacement cell with a slightly different discharge curve causes the camera to read voltage at the wrong point on its lookup table, producing jumps — 80% dropping to 40% in a handful of shots, for example. This is a display mapping mismatch, not a cell fault. Perform two full in-body charge cycles; the BMS recalibrates its threshold map against the new cell's actual curve. After that, percentage readout stabilises.
