MyGenie XR210 Replacement Battery 14.4V Ni-MH 2000mAh

MyGenie XR210 / XR210 Nestor — 14.4V Ni-MH Replacement Battery

This is a 14.4V 2000mAh Ni-MH replacement battery for the MyGenie XR210 and XR210 Nestor cordless vacuum. It slots into the same battery compartment as the original and restores suction power when the factory cell has lost holding capacity. Capacity is rated at 28.8Wh, matching the original specification.

• XR210 and XR210 Nestor compatibility: Both models run the same 14.4V battery platform with an identical connector and housing footprint. The motor controller voltage rail is the same across both variants, so one cell covers either unit.
• Bench tested on actual hardware: We ran the cell through full charge and discharge cycles on the XR210 motor circuit. The BMS held voltage under sustained suction load and tripped cleanly on simulated blockage current, then reset without manual intervention.
• Dock charging habit on the XR210: Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charge is the single fastest way to degrade a Ni-MH cell. Charge to full, remove from the dock, and return it only when the pack is depleted.

Suction dropping before the battery indicator reaches low

This is a voltage sag issue, not always a dead battery. A partially blocked filter forces the motor to draw more current than rated to maintain airflow. That extra draw pulls the cell voltage down early, which the motor controller reads as low battery and reduces power. Clean or replace the filter first — if suction recovers immediately, the battery was fine.

Capacity fade from leaving the XR210 on the dock between uses

Ni-MH cells tolerate shallow cycling poorly when combined with continuous trickle current. A vacuum left on the dock daily can lose a measurable percentage of usable capacity within a few months — not from use, but from the charger holding the cell at float voltage. The fix is simple: charge fully, pull from the dock, store the vacuum off charge. Reload the pack only when you notice suction starting to soften.
