Sony NP-F10 Cyber-shot Compatible Battery 3.7V 1440mAh

Sony CCD-CR1E / Cyber-shot DSC Series — 3.7V Li-ion Replacement Battery (NP-F10 / NP-FS11)

This 3.7V, 1440mAh Li-ion cell replaces the NP-F10, NP-FS10, NP-FS11, and NP-FS12 batteries used across Sony's CCD-CR1E camcorder and Cyber-shot DSC lineup including the DSC-P20, DSC-F505K, and DSC-F55V. The cell matches OEM voltage and physical form factor. Capacity is 1440mAh (5.33Wh) as rated.

• NP-FS series cross-compatibility: The NP-FS10, FS11, and FS12 share the same 3.7V single-cell architecture and connector pinout across Sony's InfoLithium-S platform. That shared BMS communication protocol is why one cell covers both camcorder and Cyber-shot DSC bodies without a hardware change.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a DSC-series body. The BMS handshake completed on first insertion, the InfoLithium charge-remaining display updated correctly, and protection circuitry triggered at the expected low-voltage cutoff.
• First-cycle initialisation on Sony InfoLithium bodies: On Sony InfoLithium-compatible cameras, charge the replacement cell fully through the camera body or OEM charger before your first shoot. The body uses that initial charge cycle to calibrate the battery-remaining percentage against the new cell's discharge curve — skipping it causes the indicator to read inaccurately for several cycles.

Sony InfoLithium BMS rejecting a third-party cell on first install

Sony's InfoLithium system sends a data signal between the battery and body to verify cell identity before enabling the shutter or record function. A fresh replacement cell that has never been charged may return a signal the body interprets as a fault, triggering a "battery exhausted" or no-power state on first insertion. This is not a dead cell — it's the BMS waiting for a valid charge state. Insert the battery into the OEM charger or camera body and run one complete charge cycle. After that cycle, the body registers the cell as valid and the indicator tracks normally.

Battery percentage jumping or dropping suddenly mid-shoot

The NP-FS series InfoLithium indicator maps battery percentage to a specific discharge voltage curve stored in the camera body's firmware. A replacement cell with a slightly different internal resistance profile discharges along a curve that doesn't align exactly with those stored thresholds — the body sees an unexpected voltage drop and recalculates percentage sharply downward. This typically stabilises after two or three full charge-discharge cycles as the BMS learns the new cell's actual curve. If jumping persists past three cycles, discharge the battery fully in the camera, then charge to 100% without interruption to force a full recalibration at 4.2V.
