It replaces OEM part RS-2230001774 and fits the RH9159WO\/2D0R, TY9179WO\/2D1, TY9171WO\/2D1, and over 50 additional model codes in this range. Capacity is rated at 88.06Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRH9159WO series compatibility:\u003c\/strong\u003e\n    All supported models share the same 25.9V power rail, battery connector format, and BMS communication protocol. Swapping between these variants does not require any modification — the pack seats and communicates identically across the range.\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 the RH9159WO motor platform. The BMS held voltage within spec across both hard floor and carpet load profiles, and overcurrent protection triggered correctly under sustained restricted-airflow conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline on this vacuum:\u003c\/strong\u003e\n    Do not leave the RH9159WO sitting on the charging dock between uses. This vacuum's charging circuit does not cut trickle current once full, which accelerates cell degradation. Charge to full, remove from the dock, and reconnect only when the battery is 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 BMS expects — typically caused by a partially blocked filter, not a failing battery. A restricted airflow path forces the motor to work harder, pulling current above the pack's sustained output threshold. The BMS responds by throttling or cutting power to protect the cells, which registers to the user as suction loss. Clean or replace the filter first and retest before assuming the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then 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 pushes current draw past the pack's trip threshold, the BMS disconnects the output and latches off. A short pause lets the BMS cool and reset, which is why the vacuum powers back on. The fix is removing the blockage or cleaning the filter so motor current stays within the 25.9V pack's rated output window — not replacing the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427970318426,"sku":"BWCS-RTS775VX-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427970351194,"sku":"BWCS-RTS775VX-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427970383962,"sku":"BWCS-RTS775VX-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTS775VX-1.webp?v=1779933588","url":"https:\/\/batteryweb.com\/products\/rowenta-rh9159wo-replacement-battery-259v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
