Rowenta AC232001 Cordless Vacuum Replacement Battery 3.6V 2000mAh

Rowenta AC232001/2D0 Series — 3.6V Ni-MH Replacement Battery (RS-AC3428)

This is a 3.6V, 2000mAh Ni-MH replacement battery for the Rowenta AC232001/2D0, AC232001/2D1, and AC232001/2D2 cordless vacuum cleaners. It slots into the same position as the original cell and restores motor power when the factory battery has faded or failed. Capacity is 2000mAh (7.2Wh), matching the original specification.

• AC232001 series fit: The /2D0, /2D1, and /2D2 variants share the same battery bay dimensions, connector orientation, and 3.6V motor rail — one cell covers all three. No wiring changes needed.
• Bench tested on actual hardware: We ran this cell through charge cycles on the AC232001 platform and confirmed the BMS accepted charge without fault flags. Motor start draw stayed within cutoff thresholds across repeated runs on hard floor and low-pile carpet loads.
• Dock charging habit on this vacuum: Do not leave this vacuum sitting on the dock permanently. The AC232001 charger delivers a trickle charge that continues after the cell is full. Ni-MH cells degrade faster under continuous trickle than any other condition — charge to full, then remove it from the dock.

Suction dropping before the battery indicator reaches low

This happens when the motor is drawing more current than the cell can sustain under load. A partially blocked filter forces the motor to work harder, pulling current above the cell's rated output. Voltage sags early, and suction weakens even though the indicator still shows charge remaining. Clean or replace the filter first — if suction stabilises, the battery is not the cause.

Motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a dead battery. When airflow is restricted — blocked filter, clogged nozzle, hair wrap on the brush roll — the motor draws a sustained spike the BMS interprets as a fault. It cuts power to protect the cell, then resets after the temperature drops. Clear the restriction, check the brush roll, and confirm the filter is seated correctly before assuming the battery is faulty.
