It uses the OEM part number SS-9100042161 and fits the same battery slot and connector. When the original pack no longer holds a full charge, this cell restores the vacuum to full motor voltage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRH6751WO and RH6756WO series fit:\u003c\/strong\u003e\n    These models share the same 22.2V battery bay, connector pin layout, and BMS handshake protocol. A battery that clears the handshake on one clears it on all variants in this cluster — the motor controller won't run without it.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the RH675x platform. The BMS responded correctly to motor-start current draw, held steady voltage under full suction load, and tripped appropriately when we simulated a blocked nozzle restriction.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on this vacuum:\u003c\/strong\u003e\n    Charge this battery to full, then remove the vacuum from the dock. Leaving it docked continuously exposes the cells to trickle charge current for hours beyond full capacity — this accelerates capacity fade faster than normal discharge cycling ever 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 on the RH6751WO\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the filter is partially blocked, the motor draws higher current to maintain airflow. That extra draw causes the battery's output voltage to sag under load — suction weakens even though the indicator still shows charge remaining. The BMS reads available voltage, not filter restriction, so it won't flag the real cause. Clean or replace the filter first; if suction recovers immediately, the battery was fine and the filter was the draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. Sustained restricted airflow — a blocked nozzle, a full dust cup, or a clogged filter — forces the motor to pull current above the BMS trip threshold. The BMS shuts the motor off to protect the cells, then resets after a short thermal delay. Clear the restriction, then press the power button to restart. If it trips again immediately under normal conditions, check that output voltage holds above 21.0V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427956523098,"sku":"BWCS-RTH675VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427956555866,"sku":"BWCS-RTH675VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427956588634,"sku":"BWCS-RTH675VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTH675VX-1.webp?v=1779933440","url":"https:\/\/batteryweb.com\/products\/rowenta-rh6751wo-replacement-battery-222v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
