NiKon EN-EL10 Coolpix S200 Replacement Battery 3.7V 660mAh

NiKon Coolpix S200 Series — 3.7V Li-ion Replacement Battery (EN-EL10)

The EN-EL10 is a 3.7V, 660mAh lithium-ion cell for NiKon Coolpix compact cameras. It fits the Coolpix S200, S70, S210, S220, and 23 additional S-series models. Voltage and connector are matched to the original OEM specification.

• S-series platform compatibility: These Coolpix models share the same 3.7V battery bay, connector pin-out, and BMS communication protocol. Swapping between them does not require adapters or firmware changes — the cell seats and handshakes the same way across the platform.
• Bench tested on actual hardware: We ran this cell through the Coolpix S200 body, monitoring BMS acceptance, charge termination, and discharge curve. The BMS reached charge cutoff cleanly and held voltage across a full capture session without triggering a fault state.
• First-use charge cycle on Coolpix bodies: Insert the cell and run one complete charge cycle through the camera body or OEM charger before your first shoot. Some Coolpix BMS units calibrate the battery-remaining indicator against that initial cycle — skipping it can cause the indicator to read inaccurately from the start.

Flash recycling slowing down mid-shoot on the EN-EL10

The Coolpix S200 flash capacitor draws a sharp recharge current after each fired shot. A fresh cell handles this without measurable voltage sag. As the cell approaches the lower end of its discharge curve — roughly below 3.5V — that recharge current causes a brief voltage dip, and the camera slows flash recycling to protect the circuit. If recycling gaps are lengthening, check the battery indicator. A cell reading one bar will produce this symptom even if it has not shut down yet.

Battery percentage jumping erratically on the Coolpix display

The Coolpix battery indicator maps voltage thresholds to a percentage or bar display. A new cell has a slightly different discharge curve shape than a worn OEM cell, so the camera's threshold table can misread it — jumping from full to half, or from two bars to zero, mid-session. This is a calibration mismatch, not a fault in the cell. Run two to three full charge-and-discharge cycles through the camera body to let the BMS adjust its reference points. After that, the display should track the actual state of charge accurately.
