It replaces part number YCR-MT12 when the original cell degrades and the unit can no longer complete a full cleaning cycle. The battery powers the drive motors, suction motor, and onboard navigation sensors.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eScout RX2 120 and RX3 120 compatibility:\u003c\/strong\u003e\n    Both models share the same 14.52V battery architecture, connector pinout, and BMS handshake protocol — one cell fits both without modification or adapter.\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 Scout RX-series hardware. The BMS held voltage within spec under combined drive and suction motor load, and the charger handshake completed without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for robotic vacuums:\u003c\/strong\u003e\n    Do not leave the Scout sitting on the charging dock permanently. Continuous trickle charging accelerates capacity fade in Li-ion cells. Charge the battery to full, then lift the unit off the dock until the next scheduled clean.\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 shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Scout's suction motor draws significantly more current when airflow is restricted — a partially blocked filter or debris-clogged inlet forces the motor to pull beyond its rated current. The BMS responds by throttling output voltage to stay within safe discharge limits, which the vacuum's control board interprets as reduced power rather than a battery fault. The battery indicator stays green because cell voltage hasn't actually dropped — it's the sustained overcurrent condition triggering the protection circuit. Clean the filter and check the inlet before replacing the battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. When the Scout hits a sustained restriction — thick carpet, a tangled brush roll, or a blocked exhaust — current spikes sharply and the BMS disconnects the output to protect the cells. After the cells recover to above roughly 13.0V under no load, the BMS reconnects and the unit resumes. Clear the brush roll and check that the exhaust grille is unobstructed. If trips continue on open floor with a clean filter, the cell pack itself may be faulted and replacement is the correct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428020355162,"sku":"BWCS-YCM721VX-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428020387930,"sku":"BWCS-YCM721VX-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428020420698,"sku":"BWCS-YCM721VX-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YCM721VX-1.webp?v=1779933918","url":"https:\/\/batteryweb.com\/products\/miele-scout-rx2-120-replacement-battery-1452v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
