BP-150W Sony HDW-800P Replacement Battery 14.8V 10400mAh

Sony HDW-800P / PDW-850 Series — 14.8V Li-ion Replacement Battery (BP-150W)

This 14.8V, 10400mAh (153.92Wh) Li-ion battery replaces the BP-150W, BP-95W, and BP-190WS across Sony's professional ENG and studio camcorder lineup. It fits the HDW-800P, PDW-850, DSR-250P, DSR-600P, and additional models in that family. The cell chemistry and BMS communication protocol match what Sony's body expects for charge-state reporting.

• HDW-800P and PDW-850 platform fitment: These bodies share a V-mount interface with the same data-line handshake. The battery communicates charge-state data over that bus, which is why one SKU covers both the HDW and PDW chassis without adapter or modification.
• Bench tested on actual hardware: We cycled this cell through a full charge and monitored BMS cutoff behaviour under the sustained codec-processing and lens-drive draw typical of these bodies. The protection circuit held cutoff at the correct low-voltage threshold without tripping prematurely under load.
• First-use cycle on professional camcorder bodies: On first install, run one complete charge cycle through the OEM Sony charger or the camera body's internal charging circuit before a production shoot. Some Sony BMS implementations require that initial in-body cycle to calibrate the percentage display to the new cell's discharge curve.

Why the HDW-800P rejects a valid replacement cell on first install

Sony's professional camcorder BMS runs an authentication and capacity-mapping check when it sees a new cell for the first time. If the battery hasn't completed a charge cycle from a recognised Sony charger, the body may flag it as unverified and refuse to report capacity. This isn't a fault in the cell — it's the BMS waiting for a handshake that only completes after a full charge. Insert the battery into the OEM charger, let it reach 100%, then seat it in the body. The rejection clears on the first power-up after that cycle.

Battery percentage jumping erratically during a take

This happens when the camera's voltage-threshold table — calibrated to an aged or different-capacity OEM cell — doesn't map cleanly onto the discharge curve of a new 10400mAh cell. The indicator reads voltage, not true capacity, so a steeper mid-range plateau on a fresh cell can cause the display to skip steps. It's a display calibration issue, not a cell fault. Run two full discharge-to-cutoff cycles and the body's threshold mapping re-centres — percentage readout stabilises around the 12.8V mid-discharge region.
