It fits the Canon XF100, XF105, XF300, and XF305 camcorders, along with ten additional XF-series bodies. Slot it into any of those bodies and the camera reads it the same way it reads the OEM cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXF100 \/ XF300 platform fit:\u003c\/strong\u003e\n    These four bodies share the same BP-975 battery bay, locking tab geometry, and 7.4V supply rail. The BMS handshake protocol is identical across the platform, so one cell fits all 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 discharge on an XF100 body. The BMS accepted the cell without fault codes, reported capacity within expected range, and held stable voltage through sustained 1080p recording load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on XF-series bodies:\u003c\/strong\u003e\n    Run the first full charge through the camera body or Canon OEM charger rather than a third-party unit. The XF-series BMS maps its battery-remaining display against a reference charge profile — completing one in-body cycle from flat to full lets the firmware calibrate the percentage indicator accurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the XF100 shows a dead-battery icon on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe XF100 battery indicator maps display levels against a fixed voltage-threshold table stored in firmware. A new cell's discharge curve can sit slightly outside that table on the first cycle, causing the indicator to read low or show empty before the cell is genuinely depleted. This is not a fault with the cell — it is the firmware recalibrating against unfamiliar curve data. One complete charge and discharge cycle from within the camera body resets the reference, and the indicator reads accurately from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCanon XF300 BMS rejecting the replacement cell on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome XF300 bodies flag an unrecognised battery warning the first time a non-OEM cell is inserted cold. The BMS runs an authentication check on initial contact and can return a false reject if the cell voltage is below 6.8V from storage. Remove the cell, place it in the OEM Canon charger until the charge LED switches to solid green, then re-insert. The camera will accept it on the next power-on without further prompting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333784535130,"sku":"BWCS-BP975MX-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333784567898,"sku":"BWCS-BP975MX-2","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333784600666,"sku":"BWCS-BP975MX-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP975MX-1.webp?v=1778213126","url":"https:\/\/batteryweb.com\/products\/canon-xf100-replacement-battery-74v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
