Infinuvo APQQ3-30 Cleanmate QQ-3 Replacement Battery 14.4V

Infinuvo Cleanmate QQ-3 Series — 14.4V Ni-MH Replacement Battery (APQQ3-30)

This is a 14.4V Ni-MH replacement battery rated at 3600mAh (51.84Wh) for the Infinuvo Cleanmate QQ-3, QQ-3L, QQ-3LT, and QQ3 robotic vacuum cleaners. It replaces the OEM part APQQ3-30 when the original cell pack has lost capacity or fails to hold charge. If your Cleanmate is cutting cleaning cycles short or refusing to power on from the dock, this is the cell pack that needs replacing.

• QQ-3 series compatibility: The QQ-3, QQ-3L, QQ-3LT, and QQ3 all share the same 14.4V battery bay, connector, and BMS communication protocol — one cell pack covers all four variants without modification.
• Bench tested on actual hardware: We ran this pack through the Cleanmate's charge and discharge cycle on the bench. The BMS accepted the handshake from the dock charger correctly, balancing cells without triggering a fault state at any point during the test cycle.
• Dock charging behaviour on Ni-MH: Do not leave the QQ-3 sitting on the dock permanently between cleans. Ni-MH cells on continuous trickle charge develop capacity fade significantly faster than cells charged only when depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low on the QQ-3

This happens when the motor draws more current than the cell pack can cleanly deliver at that state of charge. A partially clogged filter forces the motor to work harder, pulling amps the ageing Ni-MH cells can no longer sustain without voltage sag. The robot's onboard controller interprets that voltage dip as a low-battery condition and backs off motor speed before the indicator LED reflects it. Clear the filter first — if suction still drops early with a fresh filter, the cell pack is the cause.

QQ-3 motor cuts out mid-clean and then recovers on its own

This is a BMS overcurrent trip, not a full power failure. When the brush roll encounters a restriction — carpet fringe, a rug edge, accumulated debris — the motor stall current spikes, and the BMS opens the discharge circuit to protect the cells. Once current drops, the BMS resets and the motor restarts. This pattern repeats when the underlying draw issue is not resolved. Check the brush roll for tangled hair or debris, and verify the filter is clean before suspecting the battery pack itself.
