Vileda VR One 10.8V Replacement Battery 2600mAh 0769-03

Vileda VR One Series — 10.8V Li-ion Replacement Battery (0769-03)

This is a 10.8V, 2600mAh lithium-ion replacement battery for the Vileda VR One robot vacuum. It fits the VR One, VR 102, VR 201 PetPro, and VR 303 models. Swap it in when the original cell can no longer hold enough charge to complete a full cleaning cycle.

• VR One, VR 102, VR 201 PetPro, VR 303 compatibility: These four models share the same 10.8V power architecture, battery connector, and BMS communication protocol — one cell fits all four without modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the VR One platform. The BMS handshake completed without fault codes, and the motor controller accepted the cell's state-of-charge signal correctly throughout the test.
• Dock charging discipline on the VR series: These robots sit on their dock between every run — that's continuous trickle charge on a lithium cell. Remove the robot from the dock once the charge indicator shows full. Leaving it docked permanently is the single fastest way to degrade cell capacity on this platform.

Suction dropping before the battery indicator reaches low on the VR One

The VR One's motor draws significantly more current when the filter is partially blocked or the brush roller is restricted. That extra draw causes the battery voltage to sag under load, even when the cell still reads 70–80% charged at idle. The onboard controller interprets the voltage sag as available power, so the low-battery indicator stays off while suction performance falls away. Clean the filter and check the brush roller for hair wrap before assuming the battery is at fault.

Motor cuts out mid-run and recovers after a few seconds

This is a BMS overcurrent trip, not a battery failure. When the vacuum hits a rug edge or a blocked section, the motor briefly draws above the BMS threshold — the protection circuit opens, power cuts, then resets once current drops. A worn original battery trips this threshold sooner because its internal resistance pushes the instantaneous voltage drop further. If the new cell still trips during heavy carpet passes, check that the filter is clean and the inlet is clear before increasing load on the motor.
