It fits the RR7 series including RR7747WH4Q0 and RR7755WH4Q0 variants. OEM part numbers RS-2230002091 and 6.32.40.13-0 cross-reference directly to this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRR7 series fitment:\u003c\/strong\u003e\n    These models share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS communication protocol — so one cell pack covers the full RR7 line without modification.\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 RR7 platform. The BMS correctly negotiated with the dock charger, accepted a full charge, and delivered stable voltage through motor start and navigation load transitions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline on RR7:\u003c\/strong\u003e\n    Do not leave the RR7 on the charging dock permanently. Continuous trickle charging accelerates capacity fade on this cell pack faster than on most cordless vacuums due to the dock's constant-contact charge circuit. Charge to full, then remove from 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 RR7\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is one of the most common symptoms with a degraded RR7 battery. As internal cell resistance rises with age, voltage sags under the motor load of a partially blocked filter or dense carpet pass — even when the battery gauge still reads mid-range. The motor controller interprets that voltage sag as a load problem and reduces fan speed to protect itself. Check the filter first, but if suction recovers on hard floors and not carpet, the cell pack is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then recovers after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor fault. When suction is restricted — by a blocked filter, full dustbin, or brush roll tangle — the motor draws sustained current above the BMS threshold, and the pack shuts the output to protect the cells. The RR7 pauses, the BMS resets after a few seconds, and the robot restarts. Clean the filter and brush roll, then check that the dustbin is seated correctly. If trips continue on a clean machine, verify the replacement pack is reading at or above 14.4V resting voltage before reinstalling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427978805338,"sku":"BWCS-RTR775VX-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427978838106,"sku":"BWCS-RTR775VX-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427978870874,"sku":"BWCS-RTR775VX-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTR775VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/rowenta-rr7-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
