Vileda AS-193E9A Robotic Vacuum Compatible Battery 4.8V 3000mAh

Vileda AS-193E9A / S01 — 4.8V Ni-MH Replacement Battery

This is a 4.8V 3000mAh Ni-MH replacement battery for the Vileda AS-193E9A and S01 robotic vacuum cleaners. It slots into the battery compartment of the robot body and powers the drive motors and cleaning brush. Capacity is rated at 14.4Wh, matching the original cell specification.

• AS-193E9A and S01 compatibility: Both models share the same 4.8V four-cell Ni-MH battery architecture and connector pinout, which is why one cell fits both. The voltage rail feeds the same motor driver board across this range.
• Bench tested on actual hardware: We cycled this cell under a simulated drive-motor and brush load. The BMS held stable voltage delivery across the draw cycle and did not trip during sustained brush motor engagement.
• Dock charging behaviour: Do not leave the AS-193E9A on its charging dock permanently. Continuous trickle charge on Ni-MH cells accelerates capacity fade significantly faster than cycling charge-to-full and removing the unit from the dock.

Suction dropping before the battery indicator reaches low

This is a voltage sag issue, not a capacity issue. When the filter is partially blocked, the brush and suction motors draw more current than rated. That elevated draw pulls the cell voltage down early, and the robot interprets it as low battery. Clean the filter first — if suction recovers, the cell is not the cause. If the filter is clear and sag still happens, the cell has lost enough internal resistance tolerance that it needs replacing.

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

This is a BMS overcurrent trip triggered by sustained restricted suction. When airflow is blocked — usually a clogged filter or debris caught in the brush roll — the motor works harder and draws a spike of current. The protection circuit cuts power to prevent cell damage. The robot restarts after the BMS resets. Check the brush roll for tangled hair or debris and inspect the filter. If the behaviour continues on a clear machine, verify the replacement cell is at or above 4.8V resting voltage before first charge.
