Oregon Scientific DS9810 3.7V Compatible Battery 1050mAh

Oregon Scientific DS9810 — 3.7V Li-ion Replacement Battery

This 3.7V, 1050mAh Li-ion cell replaces the original battery in the Oregon Scientific DS9810 compact digital camera. It powers the image sensor, onboard processor, and internal electronics. Dimensions are 53.20 × 35.30 × 7.10mm — matching the original footprint for direct installation.

• DS9810 fit: The DS9810 runs a single-cell 3.7V Li-ion platform. This cell matches that voltage rail and physical form factor, so it seats correctly in the battery compartment without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS accepted charge normally, and protection circuits responded correctly at low-voltage cutoff — no false trips during normal camera operation.
• First-cycle calibration on the DS9810: Insert the new cell and run a full charge through the camera body or OEM charger before your first shoot. Some compact camera battery gauges need one complete charge cycle from within the system to map the new cell's discharge curve correctly and display accurate battery-remaining readings.

The DS9810's battery indicator reads voltage thresholds set against the original cell's discharge curve. A new third-party cell can sit slightly outside that mapped range at mid-charge, causing the indicator to misread. The camera may display a low or empty battery warning even when the cell holds a usable charge. Running one full charge-to-discharge cycle in the camera body resets that mapping and brings the indicator in line with the new cell.

Battery percentage jumping erratically during a shoot

This happens when the camera's fuel gauge is interpolating voltage from a lookup table tuned to the original cell. A replacement cell with a slightly different discharge slope hits those voltage checkpoints at different state-of-charge points, so the percentage reading jumps rather than stepping down smoothly. It is a display calibration issue — not a fault with the cell itself. Complete two full charge cycles in the camera body and the gauge typically stabilises to within a few percent of actual charge.
