Concept VR2010 Replacement Battery 14.4V 2600mAh Li-ion

Concept VR2010 / VR2000 — 14.4V Li-ion Replacement Battery (PNC423894511)

This is a 14.4V, 2600mAh lithium-ion battery for the Concept VR2010 and VR2000 cordless vacuum cleaners. It replaces OEM part PNC423894511 and restores power to the vacuum's motor and suction system. Swap it in when the original cell no longer holds a useful charge.

• VR2010 and VR2000 compatibility: Both models run the same 14.4V battery rail, use the same connector housing, and share the same BMS handshake protocol — so one replacement covers either unit without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a VR2010 unit. The BMS accepted the handshake from the charger without fault codes, and overcurrent protection tripped correctly when we simulated a blocked-airflow draw spike.
• Dock charging on the VR2010: Do not leave the vacuum sitting on the charging dock continuously. These cells develop measurable capacity fade when held at full charge on trickle current for days at a stretch. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

The VR2010 motor draws harder when airflow is restricted — a partially blocked filter forces sustained high current that the BMS reads as a voltage sag event. The battery indicator tracks cell voltage, not motor load, so it can still show mid-range while suction has already weakened. Clean or replace the filter first before concluding the battery is at fault. A clear airway lets the motor operate within its rated draw and keeps cell voltage stable throughout the charge cycle.

Motor cutting out and then recovering on its own

This is a BMS overcurrent trip, not a cell failure. When the vacuum hits a blockage or runs with a clogged filter, current spikes above the BMS threshold and the battery disconnects the output circuit to protect the cells. After a few seconds the BMS resets and the motor restarts. Check the filter, nozzle, and internal airpath for blockages. Once airflow is clear, the current draw stays within limits and the cutout stops.
