About this replacement
AEG Junior 1000 — 2.4V Ni-MH Replacement Battery (Type46)
This is a 2.4V, 3000mAh Ni-MH replacement battery for the AEG Junior 1000 cordless handheld vacuum cleaner. It fits the motorised cleaning head and suction system directly, using the Type46 cell configuration. Capacity figures come from the product data, not a third-party estimate.
- Junior 1000 cell match: The Junior 1000 runs a 2.4V two-cell Ni-MH pack at this exact voltage rail. A higher or lower cell count changes the voltage and causes either under-performance or BMS rejection at the charging circuit. This pack matches that rail without modification.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Junior 1000 platform. The BMS accepted the charge handshake cleanly and the motor drew current within rated parameters across hard floor and low-pile carpet loads.
- Dock charging on the Junior 1000: Do not leave the vacuum sitting on the charging dock permanently. Cordless vacuums on continuous dock charge develop capacity fade faster than those charged only when depleted. Charge to full, then remove it from the dock.
Suction dropping before the battery indicator reaches low on the Junior 1000
Ni-MH cells lose voltage under load faster than the indicator circuit tracks in real time. When the motor draws current against a restricted airpath — a partially blocked filter is the usual cause — voltage sag kicks in early and suction drops noticeably while the indicator still reads mid-range. The indicator reads resting voltage, not load voltage. Clean or replace the filter first, then test suction under load. If the drop persists with a clean filter, the cell itself has developed internal resistance and needs replacement.
Motor cuts out mid-clean and recovers after a few seconds
This is a BMS overcurrent trip, not a motor fault. When suction is restricted — blocked filter, clogged brush roll, or a hard blockage in the nozzle — the motor draws above its rated current to maintain airflow. The BMS cuts power to protect the cell, then resets after a short thermal or timing delay. The recovery makes it feel intermittent, but the root cause is sustained restricted suction, not a failing battery. Clear the blockage, check the filter, and confirm the brush roll spins freely before charging the battery. If trips continue on a clear path, check that resting cell voltage is above 2.2V before charging.
