AEG Quigg VC 72.09 Cordless Vacuum Replacement Battery 7.2V

AEG Quigg VC 72.09 — 7.2V Ni-MH Replacement Battery (198346)

This is a 7.2V 2000mAh Ni-MH replacement battery for the AEG Quigg VC 72.09 cordless handheld vacuum cleaner. It matches OEM part number 198346 and fits directly into the original battery housing. Capacity is 2000mAh (14.4Wh) — identical to the factory specification.

• Quigg VC 72.09 compatibility: The VC 72.09 runs a 7.2V motor rail with a Ni-MH cell stack. This replacement matches that voltage and cell count, so the motor controller receives the correct operating voltage without requiring any adapter or wiring change.
• Bench tested on actual hardware: We cycled this cell pack through discharge loads matching the VC 72.09 motor draw. The BMS held stable across full discharge cycles with no premature cutoff detected under normal suction load.
• Dock charging discipline for the VC 72.09: The Quigg VC 72.09 charges via a fixed dock that does not auto-terminate. Once the indicator shows full, remove the vacuum from the dock. Leaving it docked continuously applies a trickle charge that degrades Ni-MH cell capacity faster than normal cycling would.

Suction dropping before the battery indicator reaches low on the VC 72.09

This happens when the motor draws more current than the battery can cleanly supply at that state of charge — voltage sags under load before the cell is fully depleted. On the VC 72.09, a partially blocked filter makes this worse because restricted airflow forces the motor to work harder, pulling current spikes the aging cell cannot sustain. The battery indicator reads voltage at rest, not under load, so it lags behind what the motor actually experiences. Check and clean the filter first, then test suction — if suction stabilises, the filter was the cause, not the battery.

VC 72.09 motor cuts out mid-clean then recovers after a short pause

This is a BMS overcurrent trip, not a motor fault. When suction is sustained against a blockage or a clogged filter, current draw spikes beyond the BMS threshold and the circuit opens to protect the cells. After a brief rest the BMS resets, which is why the vacuum powers back on a minute later. Clear any blockage, clean the filter, and confirm the filter is fully dry before reinserting — a damp filter restricts airflow the same way a blocked one does and will trigger the same trip pattern.
