It fits Philco camera models V1728SL01, V1728TSL01, VCR801AV01, VCR802AV01, and three additional variants in this series. The cell slots into the original battery compartment and connects to the same BMS contacts as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV1728SL01 and VCR80x series compatibility:\u003c\/strong\u003e\n    These models share a common 12V battery rail, identical connector footprint, and the same BMS handshake protocol — which is why a single pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on compatible Philco camera hardware. The BMS accepted the pack without fault flags, and cell voltage held within the expected window across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on Philco cameras:\u003c\/strong\u003e\n    Run one complete charge through the OEM charger or camera body before your first shoot. Some Philco BMS firmware needs this cycle to calibrate the battery-remaining indicator against the new 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\"\u003eBattery percentage jumping erratically on the Philco V1728SL01 display\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe V1728SL01 maps its battery indicator to voltage thresholds tuned for the original cell's discharge curve. A new Ni-MH replacement has a slightly flatter discharge profile, so the camera's fuel gauge algorithm can mis-read state of charge at mid-range voltages. This shows up as the indicator skipping between, say, 60% and 30% without warning. One full charge-discharge cycle from within the camera body lets the BMS re-anchor its thresholds to the new cell — after that, the readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhilco camera body warm and battery draining faster under sustained video recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eVideo mode on these Philco cameras pulls current from the sensor, image processor, and any stabilisation circuit simultaneously — a combined draw well above what still photography demands. At 12V this sustained load generates more heat in both the cell and the camera body than the spec sheet suggests. If the body feels warm and charge depletes quickly during long recording sessions, break clips into shorter segments to allow the cell temperature to drop between takes. Keep cell voltage above 10.8V before starting a new recording session — below that threshold the BMS may force a protective shutdown mid-clip.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333818482778,"sku":"BWCS-VBF2E-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333818515546,"sku":"BWCS-VBF2E-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333818548314,"sku":"BWCS-VBF2E-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VBF2E_1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/philco-v1728sl01-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
