Vileda VR201 Replacement Battery 10.8V 2600mAh Li-ion

Vileda VR201 — 10.8V Li-ion Replacement Battery

This 10.8V 2600mAh Li-ion battery fits the Vileda VR201 robotic vacuum cleaner. It replaces the original cell when the unit stops holding a charge or cuts out mid-cycle. Capacity figure is taken directly from product data — 28.08Wh.

• VR201 platform fit: The VR201 runs a single 10.8V Li-ion cell pack with a specific connector orientation and BMS communication line. This replacement matches that voltage rail and connector, so the dock charger and onboard controller recognise the pack correctly.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the VR201 platform. The BMS responded correctly to the dock charger handshake, accepted a full charge without error, and released current cleanly to the drive motors and suction fan under load.
• Dock charging habit on the VR201: The VR201 is designed to return to its dock automatically, which means many units stay on charge continuously. Li-ion cells kept at 100% under trickle charge degrade faster than cells cycled normally. Charge to full, then remove the unit from the dock until the next clean.

Suction dropping before the battery indicator reaches low on the VR201

The VR201's suction fan draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder, pulling amperage above its rated draw. The BMS reads this as an abnormal load condition and throttles output voltage to protect the cell. The result is a noticeable drop in suction well before the battery level shows critical. Clean or replace the filter first, then retest — if suction holds consistently after that, the battery is not the cause.

VR201 motor cuts out briefly then recovers during a cleaning cycle

This intermittent cutout is a BMS overcurrent trip, not a faulty battery. When the brush roller or intake snags debris and stalls momentarily, current draw spikes sharply. The BMS interrupts output to prevent cell damage, then resets within seconds once current normalises. Clear any hair or debris wrapped around the brush roller and check the intake path — if the cutouts stop after that, the battery and BMS are functioning correctly.
