It replaces OEM part number 00751992 and restores power to the vacuum motor for floor and surface cleaning. Capacity is 2000mAh (28.8Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVBH14400\/01, VBH1440001, VBH14401\/03, VBH14401\/04 compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V motor rail, connector housing, and BMS handshake profile. Swapping cells between variants works because the charge circuit expects identical voltage thresholds and cell count across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the VBH14400\/01 platform. The BMS accepted the charge curve without faulting, and the motor controller did not flag a voltage mismatch at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn Ni-MH cells, voltage sag under motor load happens well before the cell is fully depleted. When the filter is partially blocked, the motor draws above its rated current, which amplifies the voltage sag further. The vacuum's electronics read that sag as low battery and reduce power to the motor. Clean the filter first — if suction recovers after that, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use and recovering after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction — a blocked nozzle or clogged filter — forces the motor to pull more current than the BMS allows, it cuts the circuit to protect the cells. After a short pause the BMS resets and power returns. Clear the blockage, check the filter is fully seated, then resume use. If trips continue with a clean filter, measure resting cell voltage — it should read at least 14.4V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428031823962,"sku":"BWCS-BSB100VX-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428031856730,"sku":"BWCS-BSB100VX-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428031889498,"sku":"BWCS-BSB100VX-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSB100VX-1.webp?v=1779933900","url":"https:\/\/batteryweb.com\/products\/siemens-vbh1440001-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
