It slots into the same battery bay and connects via the original terminal block. Capacity is 3400mAh (48.96Wh) — matching the factory spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCRP777 and FC9910 platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery bay, terminal layout, and BMS handshake protocol. One cell pack covers the entire platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a CRP777 unit and confirmed full motor spin-up, correct BMS communication, and stable voltage output through a full discharge cycle without mid-cycle cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on this vacuum:\u003c\/strong\u003e\n    Do not leave the CRP777 sitting on the charging dock permanently. These vacuums are particularly prone to capacity fade from continuous trickle charging. Charge to full, then remove from the dock until the next use.\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\"\u003eThis happens when the motor draws more current than the BMS expects — usually caused by a partially blocked filter or full dust canister. The BMS reads the current spike as a low-voltage event and reduces output to protect the cell. The vacuum feels like it's losing charge early, but the battery is not the root cause. Clean the filter and empty the canister first, then check whether the symptom persists.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained airflow restriction forces the motor to pull beyond the rated current threshold, the BMS cuts power to protect the cell. After a short rest, the BMS resets and the vacuum powers on again. Clear the filter and check the brush roll for hair or debris wrap. If the trip keeps happening on a clean machine, verify resting cell voltage — it should read above 14.0V before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426464006234,"sku":"BWCS-PHC911VX-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426464039002,"sku":"BWCS-PHC911VX-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426464071770,"sku":"BWCS-PHC911VX-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHC911VX-1.webp?v=1779933315","url":"https:\/\/batteryweb.com\/products\/philips-crp777-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
