It fits the FD22BC 011, FD22BCPET 001, FD22BR 001, and over 28 additional FD22 variants. Capacity figure is taken directly from product specifications: 2000mAh \/ 43.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFD22 Freedom platform fit:\u003c\/strong\u003e\n    All FD22 variants in this series share the same 21.6V cell architecture, connector pinout, and BMS handshake protocol. A replacement battery must match all three — voltage mismatch or an incompatible BMS signal will prevent the vacuum from powering on at all.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge cycles on the FD22 platform and confirmed the BMS communicates correctly with the charger, accepts a full charge without fault codes, and delivers stable voltage under motor load across both hard floor and carpet modes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on FD22 units:\u003c\/strong\u003e\n    Do not leave the FD22 sitting on its charging dock permanently. Continuous trickle current from the dock degrades cell capacity significantly faster than charging only when the battery is depleted. Charge to full, then remove the vacuum 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\"\u003eCordless vacuum losing suction before battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the FD22, suction can drop noticeably while the battery indicator still shows mid-charge. This usually isn't the battery failing — it's the motor drawing above its rated current due to a partially blocked filter or brush roll restriction. The BMS reads the elevated draw as a potential fault and reduces output to protect the cells. Clean the filter and check the brush roll for hair wrap before concluding the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction airflow is restricted — blocked filter, clogged inlet, or a jammed brush roll — the motor pulls sustained current above the BMS threshold. The BMS cuts power to protect the cells, then resets once current demand drops. The fix is to clear the restriction first. If the motor still trips on clean carpet with a fresh filter, check that the replacement battery's BMS is fully initialised: run one complete charge cycle before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427998924890,"sku":"BWCS-HRT121VX-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427998957658,"sku":"BWCS-HRT121VX-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427998990426,"sku":"BWCS-HRT121VX-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HRT121VX-1.webp?v=1779933799","url":"https:\/\/batteryweb.com\/products\/hoover-fd22-freedom-replacement-battery-216v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
