Capacity is 3400mAh (48.96Wh), matching the factory specification. It fits the OEM battery positions on all listed models and uses the same connector and BMS communication protocol as the original Miele pack (part nos. 9702920, 9702922, 9702925).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eScout RX1 and SLQL0 platform compatibility:\u003c\/strong\u003e\n    These models share a common battery bay format, voltage rail, and BMS handshake protocol. A single cell format covers the full listed range without adapter or modification. The connector orientation and locking tab are identical across the SLQL0, RX1-SJQL0, and RX2-SLQL0 variants.\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 Scout RX1 platform. The BMS accepted the replacement pack without fault codes, and the motor drew current within the expected operating band across hard floor and carpet modes. No overcurrent trips occurred during the cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Miele Scout models:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously. Miele Scout RX1 units left docked permanently develop capacity fade significantly faster than units charged only when depleted. Charge the pack fully, then remove it 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 SLQL0 and Scout RX1, suction loss during a cleaning pass — while the battery indicator still shows adequate charge — is almost always a motor voltage sag issue, not a cell fault. When the filter is partially blocked, the motor works harder, draws more current than rated, and the BMS throttles output voltage to protect the pack. The symptom looks like a dying battery but the cell is still holding charge. Clean or replace the filter first. If suction recovers immediately after filter cleaning, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and 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. The Scout RX1's BMS monitors sustained current draw and cuts the output circuit when draw exceeds the trip threshold — typically triggered by restricted airflow forcing the motor to labour continuously. The BMS resets after the pack temperature drops slightly, which is why the vacuum restarts after a short rest. Check the filter and airways for blockage before assuming the battery is at fault. If the motor cuts out on a clean filter with no restriction, measure open-circuit pack voltage — a healthy cell at rest should read at least 15.8V off-charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428020027482,"sku":"BWCS-MRX110VX-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428020060250,"sku":"BWCS-MRX110VX-2","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428020093018,"sku":"BWCS-MRX110VX-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRX110VX-1.webp?v=1779933917","url":"https:\/\/batteryweb.com\/products\/miele-slql0-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
