Tefal TX4469WA/2D0 Replacement Battery 4.8V 2000mAh Ni-MH

Tefal TX4469WA/2D0 — 4.8V Ni-MH Replacement Battery

This is a 4.8V 2000mAh Ni-MH replacement battery for the Tefal TX4469WA/2D0 cordless handheld vacuum cleaner. It fits directly into the original battery housing and restores power to the vacuum motor when the original cell has lost charging capacity. Capacity listed is from the product specification: 2000mAh (9.6Wh).

• TX4469WA/2D0 fit: This battery matches the voltage rail and physical form factor of the original Tefal cell. The 4.8V Ni-MH configuration is what the vacuum's motor circuit expects — substituting a different voltage or chemistry can cause the vacuum to underperform or fail to charge correctly.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Ni-MH compatible charger, confirming stable voltage delivery across the charge curve and no abnormal heat at the cell contacts.
• Dock charging habit on this vacuum: Do not leave the TX4469WA/2D0 sitting on the charging dock permanently. Continuous trickle charging is one of the fastest ways to degrade Ni-MH cells. Charge to full, then remove the vacuum from the dock until the next use.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than the cell can sustain at its current state of charge. A partially blocked filter forces the motor to work harder, pulling higher amperage and causing voltage to sag sooner than the indicator predicts. The indicator reads cell voltage, not actual remaining capacity — so visible suction loss outpaces the warning. Clear the filter and check the dust bin seal before blaming the battery.

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

This is a BMS overcurrent trip, not a dead battery. When sustained restricted airflow causes the motor to spike current draw beyond the protection threshold, the circuit cuts power momentarily. The vacuum restarts after a brief rest because the BMS resets once current demand drops. Check the filter for blockage — if suction restriction is cleared and the cutout still occurs, measure resting cell voltage; it should read at or above 5.0V after a full charge on a Ni-MH charger.
