About this replacement
Sony Cyber-shot DSC-P200 Series — 3.7V Li-ion Replacement Battery (NP-FR1)
This is a 3.7V, 900mAh Li-ion replacement for the Sony NP-FR1 battery. It fits the Cyber-shot DSC-P200, DSC-P150/B, DSC-P100/L, DSC-P200/B, and over a dozen more Cyber-shot compact cameras. Dimensions match the original at 45.90 × 35.50 × 8.35mm, so it seats into the battery bay without modification.
- Cyber-shot P-series compatibility: These models share the same NP-FR1 battery slot, voltage rail, and BMS handshake protocol. One cell covers the full range without adapter or firmware change.
- Bench tested on actual hardware: We cycled this cell through the DSC-P200 body and confirmed the BMS accepted it without rejection codes. The protection circuit responded correctly to full charge termination and low-voltage cutoff.
- First-cycle charge protocol: Run the first full charge inside the camera body or an OEM-compatible charger. Some Cyber-shot bodies need one complete in-camera charge cycle before the battery-remaining indicator maps accurately to the new cell's discharge curve.
Flash recycling slowing down before the battery indicator drops
The DSC-P200's flash capacitor draws a sharp current spike to recharge between shots. As the cell approaches the lower end of its discharge curve, internal resistance rises and the capacitor takes longer to reach full charge voltage. You'll notice this as slower flash-ready intervals before the camera shows any low-battery warning. It's not a fault — it's the cell's resistance increasing as stored charge drops. If flash recycling slows noticeably, treat it as a low-battery signal and charge soon.
Battery percentage jumping or freezing on the DSC-P200 display
The Cyber-shot P200 maps its battery indicator to voltage thresholds calibrated for the original cell's discharge curve. A new replacement cell can discharge at a slightly different rate, causing the indicator to jump between levels or stall at one bar for a long time before dropping. This is a display calibration issue, not a fault with the cell. Run two or three full charge-to-discharge cycles in the camera body and the indicator will track more accurately — aim for a resting voltage of around 4.1–4.2V at full charge as a reference point.
