It replaces OEM part numbers N047-4S2P and SS-2230002529. If the original battery no longer holds a useful charge or fails to power on, this cell restores the vacuum to full working capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRG7975, RG7987, RR7935 platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector geometry, and BMS handshake protocol. Swapping between them requires no modification — the cell 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 cell through charge and discharge cycles on the RG7975 platform. The BMS balanced all cells correctly, the charger accepted the handshake without fault codes, and overcurrent cutoff triggered at the expected threshold under simulated motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on this model:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charging on these Rowenta cordless vacuums causes measurable capacity fade within weeks. Charge to full, then remove the vacuum from the 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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the RG7975 platform, suction loss often appears to be a battery problem but is caused by voltage sag at the motor under restricted airflow. When the filter is partially blocked, the motor draws more current than rated to maintain suction — the battery voltage dips under that load and the BMS interprets it as a low-charge condition. The indicator shows two or three bars remaining, but the motor is already starved. Clean or replace the filter first. If suction returns to normal immediately after, the filter — not the cell — was the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use and recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is an overcurrent trip from the BMS, not a general power failure. On sustained restricted suction — common when picking up carpet fibres or vacuuming thick rugs — the motor draws a spike of current that exceeds the BMS threshold. The BMS cuts output to protect the cell, then resets after a brief cooldown. If this happens repeatedly on a new battery, check the filter and brush roll for blockages. Clear the restriction and the BMS should stop tripping; if the cutout continues on a clean filter at normal load, verify the charger output is reaching 16.8V at the connector terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426407055450,"sku":"BWCS-RTH793VX-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426407088218,"sku":"BWCS-RTH793VX-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426407120986,"sku":"BWCS-RTH793VX-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTH793VX-1.webp?v=1779933118","url":"https:\/\/batteryweb.com\/products\/rowenta-rg7975whns0-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
