Midea Q7 Replacement Battery 29.6V 2500mAh HB006B

Midea Q7 — 29.6V Li-ion Replacement Battery (HB006B)

This is a 29.6V, 2500mAh Li-ion battery for the Midea Q7 cordless stick vacuum. It replaces OEM part HB006B and fits directly into the Q7's battery housing. Voltage and cell count match the original pack exactly.

• Q7 platform fit: The Q7 battery bay uses a specific latch and contact alignment that is shared only within the Q7 line. The BMS in this pack is configured to communicate with the Q7's motor controller — voltage cutoff and cell protection thresholds match what the vacuum expects at full draw and at idle.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the Q7 platform. The BMS held correct cutoff under sustained motor load, and the vacuum's battery indicator tracked cell voltage accurately across the full discharge curve.
• Dock charging habit on the Q7: Do not leave the Q7 sitting on the charging dock continuously. The Q7 dock does not terminate charge in a way that protects long-term cell health — packs left docked indefinitely show measurable capacity fade within months. Charge fully, then remove from the dock.

Suction dropping before the battery indicator reaches low on the Q7

This happens when the motor draws more current than the BMS's sustained-load threshold allows. On the Q7, a partially blocked filter forces the motor to work harder — current draw climbs, and the BMS reduces output voltage to protect the cells. The result is weaker suction even though the battery reads mid-charge. Clean or replace the filter first, then retest. If suction recovers, the battery was not the cause.

Q7 motor cuts out mid-clean and then restarts after a few seconds

This is a BMS overcurrent trip, not a failing battery. When suction is restricted — blocked nozzle, full dust cup, or clogged filter — the motor stalls briefly, current spikes, and the BMS cuts power to protect the cells. The pack resets after a short thermal and current recovery window, which is why the vacuum restarts on its own. Clear the blockage and empty the dust cup before assuming the battery is faulty. If cut-outs stop after clearing the restriction, the pack is functioning correctly.
