It replaces OEM part numbers CP0111\/01, 4ICR19\/65, and 3000-014-15881. The pack slots directly into the handle unit and restores suction power to the motor drive circuit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFC87xx series compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V four-cell Li-ion architecture, the same physical connector, and an identical 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 pack through charge cycles on an FC8772 unit and monitored cell balance across all four cells. The BMS held the cutoff voltage correctly at low charge and did not trip under normal motor-start draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the dock between uses. The FC87xx dock does not terminate charge — it trickle-charges continuously, which accelerates capacity fade in Li-ion cells. Charge fully, then remove from the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the FC8772, the motor draws significantly more current when the filter is partially blocked — often two to three times the rated draw. The BMS reads this sustained high current as a low-voltage condition and begins throttling power to the motor before the indicator LED registers a low state. The result feels like a weak battery when the actual cause is restricted airflow forcing an overcurrent condition. Clean or replace the filter first — if suction recovers and holds, the battery is not the issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use and then restarts after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — by a blocked filter, a jammed brush roll, or heavy carpet — the motor stalls briefly and pulls a spike of current above the BMS threshold. The BMS cuts power to protect the cells, then resets after a few seconds once current demand drops. The fix is to clear the restriction, not replace the battery. If the cutout happens on an unobstructed surface with a clean filter, measure pack voltage under load — it should hold above 13.5V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428045357146,"sku":"BWCS-PHC877VX-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428045389914,"sku":"BWCS-PHC877VX-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428045422682,"sku":"BWCS-PHC877VX-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHC877VX-1.webp?v=1779933966","url":"https:\/\/batteryweb.com\/products\/philips-fc8772-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
