It fits the UV617, UV617R, UV647H, and UV647HB. Swap it in when the original cell no longer holds a charge and the vacuum loses suction well before the job is done.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUV617 and UV647 series compatibility:\u003c\/strong\u003e\n    These models share the same 8.4V Ni-MH battery bay, connector pinout, and charging circuit. One cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the UV617 charging cycle and confirmed the BMS accepted charge without fault flags. Discharge held steady voltage across multiple full cycles with no mid-cycle dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the UV617:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock after the pack reaches full charge. Ni-MH cells in cordless vacuums suffer capacity fade faster from continuous trickle charge than from regular use cycles. Charge to full, then pull it off 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 shows low on the UV617\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in high-draw appliances like handheld vacuums show terminal voltage sag under motor load before the indicator circuit registers a low-battery condition. The UV617 motor draws peak current under restricted airflow — a partially clogged filter makes this worse. The result is reduced suction that looks like a weak battery but is actually a voltage sag event. Clean the filter first, then check resting pack voltage — a healthy 8.4V Ni-MH should read at or above 8.0V off charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is blocked or the filter is restricted, the UV617 motor pulls sustained high current, and the protection circuit shuts the cell down to prevent damage. A short pause resets the trip and power returns. The fix is not a new battery — clear the blockage and clean or replace the filter. If cut-outs continue on a clean filter with a new pack, check that the motor brushes are not worn.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428045914202,"sku":"BWCS-EXV640VX-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428045946970,"sku":"BWCS-EXV640VX-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428045979738,"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\/euro-pro-uv617-replacement-battery-84v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
