It fits the CRP777, CRP777\/01, CRP781, and FC9910\/01\/A among other models in this range. Capacity is 2600mAh (37.44Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCRP777 and FC9910 series compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol. Swapping between variants in this family works because the cell voltage rails and communication signals are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full discharge and recharge sequences on the CRP777 platform. The BMS held cutoff correctly at low-cell voltage and allowed normal charge acceptance from the Philips dock without handshake errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on this vacuum:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock once the charge indicator shows full. The CRP777 dock does not stop passing current when the battery reaches capacity — leaving it docked continuously accelerates cell degradation faster than normal cycling would.\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\"\u003eThe CRP777 motor draws significantly more current when the filter is partially blocked or the bin is full. That extra load causes cell voltage to sag under load even when resting voltage still reads as adequate. The BMS then throttles output to protect the cells, and the motor slows — which reads as suction loss, not a battery fault. Check and clean the filter first; a clean filter cuts motor draw back to rated levels and the issue usually disappears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. When suction is restricted — blocked nozzle, clogged filter, or heavy carpet fibres — sustained high current causes the BMS protection circuit to disconnect the output. The pack needs a brief cool-down before it resets and allows the motor to restart. Clear the blockage and wait roughly 30 seconds before powering on again. If trips recur on a clean filter, measure pack resting voltage — it should sit above 13.5V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426464137306,"sku":"BWCS-PHC910VX-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426464170074,"sku":"BWCS-PHC910VX-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426464202842,"sku":"BWCS-PHC910VX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHC910VX-1.webp?v=1779933315","url":"https:\/\/batteryweb.com\/products\/philips-crp777-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
