Toshiba PDR-BT9 Replacement Battery 3.7V 1000mAh

Toshiba PDR-3010 / PDR-3310 — 3.7V Li-ion Replacement Battery (PDR-BT9)

This 3.7V 1000mAh Li-ion cell replaces the OEM PDR-BT9 battery in the Toshiba PDR-3010 and PDR-3310 compact digital cameras. It slots directly into the battery compartment with no modifications. Voltage and connector match the original Toshiba specification.

• PDR-3010 and PDR-3310 compatibility: Both models run off the same 3.7V single-cell architecture and use the same PDR-BT9 footprint, connector orientation, and BMS handshake protocol — one cell covers both bodies.
• Bench tested on actual hardware: We cycled this cell through the PDR-3010 body using the OEM charger. The BMS accepted the cell on the first charge pass, voltage held steady across the discharge curve, and the camera reported battery status without fault flags.
• First-cycle initialisation on the PDR-3010: Run a full charge cycle through the OEM charger or inside the camera body before heavy shooting. Some Toshiba camera BMS systems need one complete charge cycle to calibrate the battery-remaining display to a new cell's discharge curve. Skipping this step can cause the indicator to read full and then drop suddenly.

Flash output dropping mid-shoot on a fresh PDR-BT9 replacement

The PDR-3010's built-in flash draws a sharp current spike each time the capacitor recharges between shots. On a partially discharged cell, this spike can pull voltage below the BMS threshold momentarily, causing the camera to throttle flash power or extend recycle time. This is not a fault in the replacement cell — it reflects the internal resistance difference between a fresh cell and a fully broken-in one. After 5–10 full charge cycles, internal resistance drops and flash recovery returns to normal recycle speed.

Battery percentage jumping erratically on the PDR-3010 display

The PDR-3010 maps its battery indicator to a voltage-threshold table calibrated against the original Toshiba cell's discharge curve. A replacement cell with a slightly different curve can cause the display to read 80%, drop to 40% in a few shots, then stabilise. This is a calibration mismatch at the BMS level, not capacity loss. Run two or three full charge-discharge cycles through the camera body to allow the BMS to resync its threshold mapping. After that, the indicator should track normally above 3.5V.
