It slots into the same battery bay and connects to the same BMS handshake as the factory pack. Capacity comes in at 5000mAh \/ 90Wh — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFE18ALi and FE18ALI 011 fitment:\u003c\/strong\u003e\n    Both variants run the same 18V power rail, identical battery connector, and the same BMS communication protocol. One battery covers both. No adapters or wiring changes needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start loads and sustained suction draws. The BMS held voltage within spec under continuous operation and tripped correctly on overcurrent — no false cutoffs during normal use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charging degrades Li-ion cell capacity faster than normal charge cycles. Charge to full, 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\"\u003eThe FE18ALi motor draws significantly more current when the filter is partially blocked — often two to three times the rated draw under normal flow. That extra current load causes voltage to sag at the cells before the indicator registers a low-battery state. The result is noticeably weaker suction while the LED still shows a healthy charge. Clean or replace the filter first; if suction recovers immediately, the battery is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\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 above the BMS current threshold, the pack shuts output down as a protection measure. The BMS resets automatically once current normalises — typically within 5 to 10 seconds. If this happens repeatedly, the cause is almost always a blocked filter or a partial clog in the pickup nozzle, not a fault with the battery pack itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427977330778,"sku":"BWCS-HRF181VX-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427977363546,"sku":"BWCS-HRF181VX-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427977396314,"sku":"BWCS-HRF181VX-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HRF181VX-1.webp?v=1779933648","url":"https:\/\/batteryweb.com\/products\/hoover-fe18ali-replacement-battery-18v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
