It slots into the same battery compartment as the original cell and connects via the same multi-pin interface. Capacity comes from the product data — 3400mAh at 7.4V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCC566 \/ CC577 \/ CCHIT series compatibility:\u003c\/strong\u003e\n    These Proscan camcorder models share the same battery footprint, voltage rail, and connector pinout. The BMS in each body reads the same charge state lines, so one cell covers the full group 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 full charge and discharge on a compatible Proscan body. The BMS accepted the cell without fault codes, held a stable voltage curve across the discharge, and cut off cleanly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on Proscan bodies:\u003c\/strong\u003e\n    On first use, run a complete charge cycle through the camcorder body or OEM charger before shooting. Some Proscan BMS firmware maps the battery-remaining display to the discharge curve during that first cycle — skipping it can cause the indicator to read inaccurately for several 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 CC566 shows a dead battery icon on a freshly charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CC566 battery indicator maps percentage to voltage thresholds calibrated against the original cell's discharge curve. A new third-party cell can have a slightly different curve shape, which the firmware reads as empty even when the cell is at 80–90% charge. This is not a fault in the battery — it is a threshold mismatch in the indicator logic. One or two full charge cycles through the camera body usually re-anchors the display to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the Proscan display mid-recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readouts during recording are caused by the voltage-threshold indicator sampling at moments of high sensor and processor draw, which temporarily sags cell voltage below a display threshold. The camera firmware interprets the sag as a step-down in charge state and updates the indicator instantly. The actual cell capacity is not dropping — the display is reacting to load-induced voltage dips. Charge the cell fully to 8.4V and run one uninterrupted recording session to let the BMS re-establish its state-of-charge reference.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333665292378,"sku":"BWCS-SVD280MC-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333665325146,"sku":"BWCS-SVD280MC-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333665357914,"sku":"BWCS-SVD280MC-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVD280MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/proscan-cc566-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
