It fits the UV617, UV617R, UV647H, UV647HB, and additional models in the same series. OEM part numbers XB617UN and 1024FM both cross-reference to this cell configuration.\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 cell stack, connector pinout, and BMS handshake protocol. Swapping between UV617 and UV647 variants does not require any adapter or firmware change — the charger circuit recognises the same cell signature.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through full charge and discharge cycles on the UV617 platform. The BMS held stable under sustained motor load and tripped correctly on overcurrent, recovering without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the UV617:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock once the battery reaches full charge. Ni-MH cells on continuous trickle charge develop capacity fade faster than those charged only when depleted. Charge to full, then pull 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\"\u003eThis happens when motor draw spikes under a restricted airflow path — a blocked filter forces the motor to pull more current than the battery can sustain at rated voltage. The cell voltage sags under that load, and suction weakens even though the indicator still shows charge remaining. Clean or replace the foam and HEPA filters first. If suction recovers after the filter is cleared, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. Sustained restricted suction — from a clogged filter or blocked nozzle — pushes current draw above the BMS cutoff threshold. The BMS disconnects the cell, the motor stops, and the circuit resets once current demand drops. Check the filter and nozzle for blockages before assuming the battery is faulty. After clearing the restriction, charge the battery to 8.4V and retest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428045815898,"sku":"BWCS-EXV640VX-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428045848666,"sku":"BWCS-EXV640VX-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428045881434,"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\/shark-uv617-replacement-battery-84v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
