About this replacement
Casio Exilim Pro EX-F1 — 7.4V Li-ion Replacement Battery (NP-100)
This 7.4V, 1950mAh Li-ion cell replaces the Casio NP-100 and NP-100L batteries in the Exilim Pro EX-F1 and EX-F1BK cameras. The EX-F1 is a high-speed compact camera built for burst and fast-action shooting — a power-hungry workload that accelerates original battery wear. Capacity is rated at 14.43Wh.
- EX-F1 and EX-F1BK compatibility: Both models share the same NP-100 battery bay, connector pinout, and BMS communication protocol. Either body will accept this cell without modification.
- Bench tested on actual hardware: We cycled this cell through the EX-F1's high-speed burst mode and standard video recording. The BMS accepted the cell cleanly, voltage held stable through sustained continuous shooting, and the protection circuit triggered correctly at the low-voltage cutoff threshold.
- First-cycle calibration on the EX-F1: Run the first charge from inside the camera body or with the OEM Casio charger. The EX-F1's BMS maps battery-remaining percentages against a charge curve — one full in-camera charge cycle lets the BMS calibrate accurately against the new cell so the indicator reads correctly from the first shoot.
Why burst-mode shooting drains the EX-F1 battery faster than spec
The EX-F1 can shoot at up to 60 frames per second, which puts the sensor, processor, and buffer under near-continuous load. That draw profile is far more aggressive than the standard shot-count figures manufacturers use to rate battery life. Add continuous autofocus or 1080p video recording and the current draw climbs further. A battery that tests well on a single-shot cycle may still deplete noticeably faster when burst mode is the primary shooting mode — this is normal behaviour for the platform, not a cell defect.
Battery percentage jumping erratically on the EX-F1 display
This happens when the camera's BMS hasn't yet mapped its voltage-threshold table against the new cell's discharge curve. The indicator samples terminal voltage and translates it to a percentage — a fresh cell with no calibration history can cause the reading to jump 20–30% between shots. It does not mean the cell is faulty. Perform one complete charge-to-full and run-to-cutoff cycle in the camera body. After that cycle, the BMS recalibrates and the percentage display stabilises.
