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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHDW-800P and PDW-850 platform fitment:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use cycle on professional camcorder bodies:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the HDW-800P rejects a valid replacement cell on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSony'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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during a take\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333692260442,"sku":"BWCS-SDW800MC-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333692293210,"sku":"BWCS-SDW800MC-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333692325978,"sku":"BWCS-SDW800MC-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDW800MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/sony-hdw-800p-replacement-battery-148v-10400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
