It fits the Sony PMW-EX1, PMW-EX1r, PMW-EX3, PMW-F3, and seventeen additional PMW-series camcorders that use the BP-U mount. Voltage and capacity figures match the original Sony BP-U60 cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBP-U mount compatibility across PMW-EX and PMW-F3 platforms:\u003c\/strong\u003e\n    All listed models share the same 14.8V BP-U rail, a standardised four-contact connector, and a BMS handshake protocol that reads cell voltage, temperature, and charge state. That shared architecture is why one battery spans the entire PMW lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a PMW-EX1 body. The BMS accepted the handshake on first contact, reported charge state accurately, and the low-voltage cutoff triggered cleanly at the expected threshold — no false shutdowns under codec load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on PMW-EX1 and PMW-EX3:\u003c\/strong\u003e\n    Charge this battery fully in the OEM Sony BC-U1 or BC-U2 charger before the first recording session. Some PMW-series bodies require a complete charge cycle via the OEM charger before the battery-remaining display maps correctly to this 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 PMW-EX1 draws harder than the rated capacity suggests\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PMW-EX1 runs simultaneous loads across its 3-CMOS sensor array, XDCAM EX codec engine, viewfinder, and onboard fans — all from the same 14.8V rail. Peak draw spikes during codec write bursts and when the camera spins up from standby. A cell rated at 5200mAh under a steady 1A test load will see a higher effective drain under this combined draw, which is normal behaviour for this camera body. That gap between bench-rated capacity and real-world result is physics, not a cell defect.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the PMW-EX1 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PMW-EX1's fuel gauge maps battery percentage to a voltage-threshold curve calibrated against the original BP-U60 discharge profile. A new replacement cell may have a slightly different internal resistance, causing the display to skip percentage steps rather than count down smoothly. This is a gauge-mapping issue, not a cell fault. Run one full charge-discharge cycle inside the camera body, and the BMS recalibrates its threshold map to the new cell's actual discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333767135322,"sku":"BWCS-BU60MC-1","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333767168090,"sku":"BWCS-BU60MC-2","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333767200858,"sku":"BWCS-BU60MC-3","price":126.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BU60MC-1.webp?v=1778213067","url":"https:\/\/batteryweb.com\/products\/sony-pmw-ex1-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
