It fits the HSV40 and HSV4007 models directly, using the same voltage rail and connector as the original pack. Capacity is rated at 43.2Wh — matching the original specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHSV40 and HSV4007 fitment:\u003c\/strong\u003e\n    Both models share the same 14.4V motor circuit, connector housing, and BMS communication protocol — which is why one battery pack covers the full HSV40 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-discharge cycles on the HSV40 platform. The BMS accepted the cell chemistry without fault codes, and the motor draw stayed within the overcurrent threshold under full suction load on carpet.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the HSV40:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Ni-MH cells in cordless vacuums develop capacity fade significantly faster under continuous trickle charge. 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 on the HSV40\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is working harder than the battery's current output can sustain — usually caused by a partially blocked filter. A restricted airway forces the motor to draw above its rated current, which causes voltage sag at the cell level before the indicator registers a low state. The pack itself is not failing; it is responding to an abnormally high load. Clean or replace the filter first, then retest under normal carpet load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHSV40 motor cuts out mid-use then recovers 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 — blocked nozzle, saturated filter, or debris in the airway — the motor draws a sustained current spike that exceeds the BMS protection threshold and shuts the circuit. The pack recovers once it cools and the BMS resets, typically within 60 to 90 seconds. Clear the obstruction and confirm the filter is clean before restarting; if the trip repeats immediately, check the nozzle path for a hard blockage before assuming a battery fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428056432730,"sku":"BWCS-HSV400VX-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428056465498,"sku":"BWCS-HSV400VX-2","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428056498266,"sku":"BWCS-HSV400VX-3","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HSV400VX-1.webp?v=1779934015","url":"https:\/\/batteryweb.com\/products\/hoover-hsv40-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
