OEM part numbers 9702922, 9702925, and 9702920 all cross-reference to this cell configuration. Capacity is rated at 37.44Wh — matching the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSLQL0 and Scout RX1 platform fit:\u003c\/strong\u003e\n    These models share a 14.4V power rail, the same physical connector, and an identical BMS handshake protocol. A single cell configuration covers all variants in the Scout RX series because Miele kept the battery architecture consistent across that platform generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on an RX1 unit. The BMS correctly reported state of charge to the vacuum's indicator, accepted a full charge without tripping the charger, and cut off cleanly at the low-voltage threshold — no forced shutdowns at partial charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Scout RX series:\u003c\/strong\u003e\n    The Scout RX models are often left on the wall dock between uses. Continuous trickle current from the dock degrades cell capacity faster than normal cycling. Charge to full, then remove the vacuum from the dock until the next use.\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 on the SLQL0\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SLQL0 motor draws higher current when airflow is restricted — a partially blocked filter forces the motor to work harder, pulling more amps than the BMS expects under normal load. When current spikes beyond the pack's rated discharge rate, the BMS reduces output voltage to protect the cells. The vacuum reads this as a power drop, not a low-battery event, so the indicator stays green while suction falls noticeably. Clean or replace the filter first; if suction recovers immediately, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then restarts after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a faulty motor. Under sustained restricted airflow — carpet pile, blocked brush roll, or a clogged pre-filter — current draw spikes hard and the BMS trips the output circuit to protect the cells. The pack resets after a brief thermal and voltage recovery, which is why the vacuum restarts after 30–60 seconds. Clear the blockage, confirm the filter is clean, then restart; if the trip stops occurring, the pack is functioning correctly and the restriction was the root cause.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428019929178,"sku":"BWCS-MRX100VX-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428019961946,"sku":"BWCS-MRX100VX-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428019994714,"sku":"BWCS-MRX100VX-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRX100VX-1.webp?v=1779933917","url":"https:\/\/batteryweb.com\/products\/miele-slql0-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
