AEG 00273713 Cordless Vacuum Replacement Battery 14.4V 1500mAh

AEG 00273713 / AG3004 Series — 14.4V Ni-MH Replacement Battery (2199035029)

This is a 14.4V, 1500mAh Ni-MH replacement battery pack for AEG cordless handheld vacuum cleaners. It fits the 00273713, AG3004, 900273725, and AG3006 models, among others. The pack slots into the same battery bay as the original and connects to the same charging circuit.

• AG3004 and 00273713 series compatibility: These models share the same 14.4V motor rail, battery bay geometry, and charging contact layout. The BMS on each communicates over the same voltage thresholds, so one pack covers the full range without modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the AG3004 platform. The BMS held cutoff correctly at low-cell voltage and the charger recognised the pack without error.
• Dock charging habit on AEG handhelds: Do not leave this vacuum on the charging dock permanently between uses. Ni-MH cells in these packs degrade faster under continuous trickle charge than under normal charge-and-remove cycles. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than the pack can deliver cleanly — voltage sags under load even though the cell charge level looks adequate. On the AG3004 and related models, a partially blocked filter forces the motor to work harder, pulling sustained high current and triggering voltage sag earlier in the discharge cycle. The battery indicator reads cell voltage, not remaining capacity, so it lags behind what the motor is actually experiencing. Check and clear the filter first — if suction still drops early, the pack itself may have lost capacity and needs replacement.

Motor cuts out mid-use then recovers after a short pause

This is a BMS overcurrent trip, not a flat battery. When suction is restricted — blocked nozzle, full dust container, clogged filter — the motor load spikes above the pack's continuous current rating and the BMS shuts the output to protect the cells. The pack recovers within seconds once the trip clears. To stop it recurring, empty the dust container, clean the filter, and clear any blockage at the nozzle before restarting. If the cutout happens on unrestricted airflow, verify the pack is fully charged to 14.4V before assuming a fault.
