It slots into the same battery compartment as the original pack and supplies the same voltage rail. Capacity is 3400mAh (25.16Wh) as specified in the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCC-8251, PRO-V730, and PRO-V742 compatibility:\u003c\/strong\u003e\n    These three RCA camera models share the same 7.4V battery footprint, connector pinout, and BMS communication protocol. One pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the CC-8251. The BMS handled cell balancing correctly and the camera's fuel gauge tracked state-of-charge without error flags during video recording loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use initialisation on RCA cameras:\u003c\/strong\u003e\n    After installing this pack, let the camera complete one full charge cycle via the in-body charger before shooting. The CC-8251 and PRO-V series calibrate their battery indicator against the first full charge — skipping this causes the percentage display to read erratically during early sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CC-8251 shuts off mid-video recording with a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eVideo recording draws significantly more current than still photography — the sensor, image processor, and write buffer all run simultaneously. If the replacement pack's BMS has a conservative overcurrent threshold, it can trip during the sustained load spike at recording start. This appears as a clean shutdown rather than a low-battery warning. The fix is to let the camera complete one full charge-discharge cycle, which allows the BMS to settle its current threshold against the camera's actual load profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or freezing on the RCA camera display after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CC-8251's indicator maps voltage curves from the original pack during its first charge cycle. A new cell has a slightly different discharge curve, so the display can show a frozen or jumping percentage until the camera re-maps the thresholds. This is not a fault in the battery. Charge the pack fully to 8.4V, then run the camera down to auto-shutoff, and charge again — after this cycle the indicator tracks normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333664899162,"sku":"BWCS-SDC46XL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333664931930,"sku":"BWCS-SDC46XL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333664964698,"sku":"BWCS-SDC46XL-3","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDC46XL-1.webp?v=1778616210","url":"https:\/\/batteryweb.com\/products\/rca-cc-8251-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
