Euro Pro Shark UV617 Replacement Battery XBP617 8.4V

Euro Pro Shark UV617 — 8.4V Ni-MH Replacement Battery (XBP617)

This is an 8.4V, 1500mAh Ni-MH replacement battery for the Euro Pro Shark UV617 cordless hand vacuum. It also fits the UV647H, UV647, and V1730 models, which share the same voltage rail and connector. Swap the XBP617 when the original cell no longer holds a usable charge.

• UV617 / UV647 / V1730 compatibility: These models run on the same 8.4V Ni-MH pack with the same physical connector and cell count. The motor control circuit expects the same charge curve across all four variants, so one replacement covers the full group.
• Bench tested on actual hardware: We cycled this cell through the UV617 motor under load and monitored BMS response. The pack reached rated capacity within three full charge-discharge cycles and held voltage under sustained suction without tripping the overcurrent cutoff.
• Dock charging habit on the UV617: Do not leave this vacuum sitting on the dock permanently between uses. Ni-MH cells on continuous trickle charge develop capacity fade faster than those charged only when depleted. Charge fully, then remove from the dock.

Suction dropping before the battery indicator reaches low on the UV617

The UV617 motor draws higher current when the filter is partially blocked. Even a lightly loaded Ni-MH pack will sag in voltage under that elevated draw, which the motor interprets as a depleted cell before the indicator registers low. The result is noticeably weaker suction while the battery gauge still shows charge. Clean or replace the filter first — if suction recovers immediately, the pack is likely fine and the filter was the restriction.

UV617 motor cuts out mid-use then restarts after a pause

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to pull beyond the pack's rated discharge current, the BMS disconnects the output to protect the cells. The unit recovers once the BMS resets — typically within 30 to 60 seconds. Check the filter and nozzle for blockages before assuming the battery is faulty. If the cutout stops after clearing the obstruction, the replacement cell is working correctly.
