It fits the DCR-PC9, DCR-PC115, DCR-PC120BT, DCR-DVD300, and 66 additional models in the same family. The physical footprint matches OEM dimensions at 49.10 × 40.80 × 24.20mm — it seats and latches the same way.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFF-series camcorder platform:\u003c\/strong\u003e\n    These models share the same battery bay geometry, connector pinout, and BMS handshake protocol. Sony used the NP-FF70\/71 cell across the PC and DVD sub-series precisely because the power management circuit was unified — swapping between those models requires no adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the DCR-PC9 body. The BMS accepted it on the first charge cycle, thermal monitoring stayed active throughout discharge, and the protection circuit tripped correctly at low-voltage cutoff without needing a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge via camera body:\u003c\/strong\u003e\n    On these Sony camcorders, insert the new cell and charge it once through the camera body — not a standalone charger — before heavy recording. The onboard BMS maps its fuel gauge to the new cell's discharge curve during that first in-body charge, which is what makes the battery-remaining indicator accurate from that point forward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony BMS rejecting a third-party cell on first install in DCR-series camcorders\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's NP-FF series camcorders use a multi-pin connector that carries data alongside power. On first insertion of a new cell, the camera's BMS checks cell identification data before it will display a charge level or enable recording. If the camera shows a flashing battery icon or locks the record button immediately after you insert the replacement, it hasn't completed that check yet. One full charge cycle through the in-body charger — not a wall-mount standalone unit — typically completes the handshake and clears the lockout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or dropping suddenly during playback or recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DCR-PC9's fuel gauge maps a fixed voltage curve to its percentage display. A new replacement cell has a slightly different internal resistance profile than the original Sony cell the firmware was calibrated against, so the indicator can read 60% and then jump to 20% without warning. This happens because the camera hits a voltage threshold it associates with a nearly depleted original cell — but the replacement still has usable capacity below that point. Run two full charge-and-discharge cycles through the camera body and the indicator will track more accurately, typically settling within 10–15% of actual state of charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333923438682,"sku":"BWCS-FF70-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333923471450,"sku":"BWCS-FF70-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333923504218,"sku":"BWCS-FF70-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FF70_1.webp?v=1778213576","url":"https:\/\/batteryweb.com\/products\/sony-dcr-pc9-replacement-battery-74v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
