It fits the original battery slot and runs on the same voltage rail as the factory cell. Replace this when your existing battery no longer holds charge or the vacuum loses suction well before the indicator shows low.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInventum cordless vacuum platform:\u003c\/strong\u003e\n    Inventum stick vacuums on this voltage rail share the same battery housing, connector, and BMS handshake. One cell covers the full range of models that accept part number 61CNMR1966.\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 compatible hardware. The BMS responded correctly to both standard charge termination and overcurrent conditions — no false trips under normal motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum on the charging dock permanently. Cordless vacuums on continuous dock charge develop capacity fade significantly faster than those charged only when depleted. Charge to full, then remove 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\"\u003eThis is a voltage sag issue, not always a dead battery. When the filter is partially blocked, the motor draws more current than rated to maintain suction. The extra draw pulls cell voltage down faster than normal, causing the motor to slow before the indicator registers low. Clean the filter first — if suction still fades early, the cell has lost capacity and needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip caused by sustained restricted airflow. When suction is blocked — by a clogged filter or a jammed nozzle — the motor strains and current spikes above the BMS threshold. The BMS disconnects the cell to protect it, then resets once current drops. Clear the blockage, confirm the filter is clean, and resume use. If cut-outs continue with a clear filter, check that the replacement cell voltage reads at least 25.0V on a multimeter after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427983163482,"sku":"BWCS-GNX701VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427983196250,"sku":"BWCS-GNX701VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427983229018,"sku":"BWCS-GNX701VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNX701VX-1.webp?v=1779933648","url":"https:\/\/batteryweb.com\/products\/inventum-replacement-battery-252v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
