VAC-905 Toshiba PDR-151 Compatible Battery 12V 1800mAh

Toshiba PDR-151 — 12V Ni-MH Replacement Battery (VAC-905)

This is a 12V, 1800mAh Ni-MH replacement battery for the Toshiba PDR-151 compact digital camera. It replaces the original VAC-905 cell when the factory unit degrades and can no longer hold a usable charge. Capacity figure is 1800mAh (21.6Wh) as rated in the product specification.

• PDR-151 compatibility: The PDR-151 draws from a single 12V Ni-MH cell — a chemistry and voltage rail specific to this camera line. This replacement matches that rail, the physical contact layout, and the connector geometry the camera body expects.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench to verify the BMS handshake completes and the camera body accepts the cell without throwing an error state. Charge acceptance and voltage delivery both checked within spec.
• First charge cycle on the PDR-151: Run the first full charge through the OEM charger or inside the camera body before shooting. Some Toshiba camera BMS implementations need that initial in-body charge cycle to calibrate the battery-remaining indicator to the new cell's discharge curve.

Ni-MH cells have a flatter discharge curve than Li-ion, and the PDR-151's fuel gauge maps voltage thresholds to estimate remaining charge. A new replacement cell's curve won't always align with the camera's stored reference until one or two full cycles complete. The indicator reads low — or triggers a dead-battery warning — even when the cell is carrying adequate voltage. Run one full charge-to-discharge cycle in the camera body and the gauge recalibrates to the new cell's curve. After that cycle, the indicator tracks accurately.

Flash not fully recycling between shots on new replacement cell

The PDR-151's flash capacitor pulls a sharp recharge current spike after each firing. At end of cell life — or on a replacement cell that hasn't finished its first charge cycle — internal resistance is higher than it will be once the cell is broken in. That added resistance causes voltage sag during the recharge spike, slowing capacitor refill and extending recycle time between shots. Complete one full charge cycle first. If recycle lag persists beyond the break-in period, check that resting voltage after a full charge is reaching at least 13.2V — six cells at 2.2V each — before diagnosing a faulty unit.
