Siemens FA114 Replacement Battery 6V 2100mAh Ni-MH

Siemens FA114 / FA116 / FA117 / FA118 — 6V Ni-MH Replacement Battery

This is a 6V, 2100mAh Ni-MH replacement battery for Siemens digital cameras including the FA114, FA116, FA117, and FA118 series. It slots into the same battery compartment as the original cell and delivers the same voltage rail. Capacity is 2100mAh — use the product data, not any third-party listing that quotes a different figure.

• FA114 / FA116 / FA117 / FA118 compatibility: These models share the same battery form factor, 6V voltage rail, and BMS handshake protocol — one cell covers the entire group. No modification needed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on camera hardware and confirmed BMS acceptance, accurate voltage delivery at load, and correct charge termination at full capacity.
• First-install charge cycle: Run one complete charge cycle through the camera body or OEM charger before heavy shooting. Some Siemens camera BMS systems require this initial cycle to map the new cell's discharge curve and display battery level accurately.

Battery percentage jumping erratically on the FA114 display

Ni-MH cells have a flatter discharge curve than the original cell calibration may expect, especially when the BMS hasn't mapped a new cell yet. The camera's fuel gauge reads voltage thresholds from a stored profile — if the profile doesn't match the new cell's curve, the percentage display jumps. Run one full charge-to-discharge cycle through the camera body. After that cycle, the BMS resets its threshold mapping and the display stabilises to within a few percentage points of actual remaining charge.

Flash not fully recycling between shots on a new cell

Flash recycling depends on the capacitor recharge current the battery can sustain under load. If the cell hasn't completed its break-in cycle, internal resistance is higher than rated — the capacitor recharges slower and the flash fires at reduced intensity. This isn't a faulty cell; it corrects after two to three full charge cycles. Once internal resistance drops to spec, flash recycle time returns to normal and you'll see consistent output across a full shoot.
