About this replacement
Casio Exilim EX-Z2000 / EX-Z200 — 3.7V Li-ion Replacement Battery (NP-110)
This is a 3.7V, 1150mAh Li-ion cell replacing the Casio NP-110 battery. It fits the Exilim EX-Z2000, EX-Z200, Exilim Zoom EX-Z2000, and EX-Z2000BK, plus 19 additional Exilim variants. Use it when the original cell no longer holds a charge or fails to power the camera at all.
- Exilim EX-Z2000 and EX-Z200 series fit: Both cameras share the same NP-110 battery bay, connector pinout, and BMS handshake protocol — one cell covers the full range of NP-110, NP-110DBA, NP-110L, and NP-160 OEM part numbers.
- Bench tested on actual hardware: We cycled this cell through the EX-Z200 body using the OEM charger. The BMS accepted the cell on first charge, reported battery-remaining without error, and held voltage above 3.5V through the discharge curve.
- First-use charge cycle on Exilim bodies: Run one full charge through the camera body or OEM charger before your first shoot. The Exilim BMS maps its battery-remaining indicator against a known discharge curve — skipping this step causes the indicator to jump erratically until the camera completes its calibration pass.
Flash recycling slowing down before the battery indicator shows low
The EX-Z2000's flash capacitor draws a high recharge current after each shot. As the cell approaches the lower end of its discharge curve — typically below 3.6V — available current drops and the capacitor takes longer to reach full charge. The camera body may still show one or two bars on the battery indicator while flash recycling noticeably lags. If you see recycling delays, check actual cell voltage with the OEM charger; below 3.55V, recharge before continuing a flash-heavy session.
Battery percentage jumping or resetting to full mid-shoot on a new cell
The Exilim's battery-remaining display maps voltage thresholds to percentage steps based on a learned discharge profile. A new cell has a slightly different discharge curve than the worn original, so the camera's threshold map initially misfires — showing a sudden jump up or down. This corrects itself after one or two full charge-to-discharge cycles in the camera body. Run the cell down to auto-off at least once, then charge fully; the indicator stabilises from that point.
