It replaces OEM part SS-9100042161 and fits the same connector and BMS handshake as the original pack. Capacity is 3500mAh (77.7Wh) — matching the factory specification for this motor platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRH6751WO \/ RH6756WO \/ RH6753WO fit group:\u003c\/strong\u003e\n    These models share the same 22.2V motor rail, battery connector, and BMS communication protocol. A single replacement pack covers the full variant list — the BMS on each unit expects the same voltage profile and cell count from this six-cell Li-ion configuration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles on the RH675x platform and confirmed the BMS handshake initialised cleanly, charging accepted without fault codes, and the overcurrent protection tripped at the correct threshold under a simulated blocked-filter load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on this vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. The RH675x series does not terminate charge aggressively — extended dock time causes trickle charge stress on the cells. Charge to full, then remove from the dock and store the vacuum upright off the base.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping well before the battery indicator reaches low on RH675x\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn this platform, the motor controller reduces power output when cell voltage sags under sustained load — even if the indicator still shows charge remaining. A partially blocked filter forces the motor to draw above its rated current, which deepens the voltage sag and triggers the controller's under-voltage response early. The battery is not necessarily the root cause. Clean or replace the filter first, then test again — if suction holds across a full charge cycle, the cells are functioning correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a flat battery. When the RH675x motor draws a sustained spike — typically from a blockage or a heavily restricted filter — the BMS opens the discharge circuit to protect the cells. The pack resets once temperature and current normalise, which is why the vacuum restarts a minute or two later. Clear any blockage in the nozzle and floor head, wash the filter, and allow it to dry fully before retesting. If trips continue with a clean filter on a new pack, inspect the brush-roll for tangled debris causing sustained motor drag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427956326490,"sku":"BWCS-RTH676VX-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427956359258,"sku":"BWCS-RTH676VX-2","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427956392026,"sku":"BWCS-RTH676VX-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTH676VX-1.webp?v=1779933440","url":"https:\/\/batteryweb.com\/products\/rowenta-rh6751wo-replacement-battery-222v-3500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
