It also fits the RH8801WH\/9A0, RH8801WH\/9A2, and RH8837K0\/9A0 models. It replaces OEM part RS-RH5272 and restores power to the motorized cleaning head and suction system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRH8801 and RH8837 compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V cell configuration, connector pinout, and BMS handshake protocol. A single cell pack covers all variants in the series 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 full charge and discharge cycles on RH8801-series hardware. The BMS held the correct charge threshold and cut off at the expected low-voltage floor without triggering false motor stops.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for RH8801 series:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock continuously. Rowenta stick vacuums in this series cycle trickle current through the pack even when full, which accelerates cell degradation. Charge to full, remove from dock, recharge only when depleted.\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\"\u003eThis happens when the motor draws more current than the cell can deliver at its present state of charge. A partially blocked filter dramatically increases motor load, pulling the pack voltage below the point where suction stays consistent — even at 50–60% charge remaining. The BMS doesn't trip a full cutoff, so the indicator stays green while suction falls. Clean the filter first, then retest. If suction holds steady across a full discharge cycle, the filter was the cause, not the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out briefly then recovers during use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip caused by a sustained spike in motor draw — most often from restricted airflow at the head or a clogged filter. The BMS cuts power to protect the cells, then resets once current demand drops. It is not a faulty battery. Clear the blockage, check the filter, and confirm airflow through the cleaning head is unobstructed. If trips continue on a clean filter with this replacement pack, measure resting pack voltage — it should sit at or above 16.4V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427963207770,"sku":"BWCS-RTH810VX-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427963240538,"sku":"BWCS-RTH810VX-2","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427963273306,"sku":"BWCS-RTH810VX-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTH810VX-1.webp?v=1779933588","url":"https:\/\/batteryweb.com\/products\/rowenta-rh8801wh2d2-replacement-battery-144v-3500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
