Shark UV610 Replacement Battery 7.2V 3000mAh Ni-MH XBP610

Euro Pro Shark UV610 Series — 7.2V Ni-MH Replacement Battery (XBP610)

This is a 7.2V, 3000mAh Ni-MH replacement battery for the Shark UV610 handheld UV sanitizing vacuum. It fits the UV610, UV610BL, UV610C, UV610DT, and over a dozen additional UV610 variants. Same voltage, same form factor, same XBP610 specification as the original cell pack.

• UV610 series compatibility: All UV610 variants share the same 7.2V Ni-MH battery rail and XBP610 connector configuration. The BMS in each model negotiates charge acceptance identically, so one cell pack covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through charge and full-load discharge on the UV610 motor. The BMS held charge termination correctly and the UV lamp circuit stayed live through the discharge curve without tripping overcurrent protection.
• Dock charging discipline for Ni-MH cells: The UV610 charger applies a trickle current after the cell reaches full charge. Leave the vacuum on the dock permanently and the Ni-MH cells develop memory effect within weeks. Charge to full, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low on the UV610

This is a voltage sag issue, not a simple capacity problem. When the UV610 motor draws against a restricted airflow path — a clogged filter or partial blockage — current demand spikes and cell voltage sags under load before the indicator has time to respond. The indicator reads resting voltage, not load voltage, so it lags behind what the motor is actually seeing. Clean the filter first and confirm airflow is unrestricted before assuming the battery is at fault.

UV610 motor cuts out mid-clean then recovers after a few seconds

This is a BMS overcurrent trip, not a failed battery. When suction is sustained against a blockage or a heavily loaded carpet, current draw exceeds the BMS threshold and it cuts the output circuit to protect the cells. The BMS resets automatically after a few seconds once current demand drops. Check the filter and clear any blockage at the nozzle — if current draw returns to normal range, the cutout stops. If trips continue on a clean, unobstructed path, measure resting cell voltage; anything below 6.0V points to a degraded pack needing replacement.
