It replaces OEM part numbers EB-91053 and XB617GE. Fits the DO206SW-34 Pro and 206SW-34 Pro variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDO206SW-34 Pro platform fit:\u003c\/strong\u003e\n    Both the DO206SW-34 Pro and 206SW-34 Pro share the same 8.4V cell pack configuration and connector housing. The BMS communicates charge state over the same two-pin thermal line, so voltage rail and termination behaviour match across both variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell pack using the original Domo charger. The BMS correctly terminated charge at full capacity and tripped overcurrent protection under a simulated motor-stall load, then reset cleanly on reconnect.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\u003c\/strong\u003e\n    Do not leave the DO206SW-34 Pro sitting on the charging dock continuously between uses. Ni-MH cells in cordless vacuums develop capacity fade significantly faster under permanent trickle charge. Charge fully, then remove 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\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the motor draws more current than rated when airflow is restricted — a partially blocked filter or full dust cup forces the motor to work harder. That elevated draw causes voltage to sag on the Ni-MH pack before the indicator circuit registers a low-charge condition. The indicator reads state of charge, not motor load, so the two fall out of sync under restriction. Clear the filter and empty the dust cup first — if suction recovers, the battery is not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction causes motor current to spike past the BMS threshold, the pack shuts the output rail to protect the cells. After a few seconds the BMS resets and the motor restarts. Check the filter and clear any blockage at the nozzle or brush head — if the cutouts stop, the pack is functioning correctly. If the motor still trips on a clean filter with a fresh cell pack, test pack voltage under load; a healthy 8.4V Ni-MH should hold above 7.2V during normal motor draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428046012506,"sku":"BWCS-EXV640VX-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428046045274,"sku":"BWCS-EXV640VX-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428046078042,"sku":"BWCS-EXV640VX-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EXV640VX-1.webp?v=1779933939","url":"https:\/\/batteryweb.com\/products\/domo-do206sw-34-pro-replacement-battery-84v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
