Nytex ND-6360 Replacement Battery 3.7V 1050mAh Li-ion

Nytex ND-6360 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1050mAh Li-ion cell built to the NP-60 form factor, fitting the Fujifilm FinePix series compact cameras. It slots into cameras that originally shipped with Fujifilm's NP-60 battery. Voltage and physical dimensions match the OEM cell: 53.20 × 35.30 × 7.10mm.

• FinePix NP-60 platform fit: Fujifilm's compact FinePix models sharing the NP-60 footprint use the same 3.7V rail and matching connector orientation. The cell slots directly into the battery compartment without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on NP-60 compatible hardware. The BMS accepted the cell, protection circuits triggered correctly at low-voltage cutoff, and the camera body completed a full charge cycle without error flags.
• First charge cycle in camera body: Fujifilm FinePix cameras calibrate their battery-remaining indicator during the first charge cycle from inside the camera body. Charge this cell fully via the camera before your first shoot — skipping this step causes the indicator to read inaccurately from the start.

Flash recycling slowing down as the ND-6360 cell drains

The flash capacitor draws a sharp burst of current every time it recharges between shots. As the cell approaches the lower end of its discharge curve, internal resistance rises and the voltage sags briefly under that load. The camera body detects the sag and may extend the recycle delay or flag a low-battery warning before the cell is actually flat. If flash recycle time is noticeably longer than it was at the start of the session, the cell has around 10–15% charge left and the camera is managing draw to protect the circuit.

Battery percentage jumping erratically on the camera display

Fujifilm FinePix cameras map voltage thresholds to their percentage display using the OEM cell's discharge curve. A replacement cell with a slightly different discharge profile can cause the indicator to skip between values — jumping from 80% to 40% in a few shots, for example. This is a display calibration issue, not a cell fault. Run one full charge-to-discharge cycle through the camera body and the BMS will remap its threshold markers to the new cell's actual curve, settling the readout to within a few percent.
