Eurobot XR210 Cordless Vacuum Replacement Battery 14.4V 2000mAh

Eurobot XR210 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Eurobot XR210 cordless vacuum cleaner. It fits the XR210's battery bay directly and powers the motor at the same voltage as the original cell. Capacity is 2000mAh (28.8Wh), matching the factory specification.

• XR210 motor compatibility: The XR210 runs a brushed DC motor matched to a 14.4V supply rail. Dropping voltage — as a degraded original cell does — causes the motor to spin slower, which drops airflow and suction before the indicator lamp even registers low. This cell restores the correct voltage to the motor under load.
• Bench tested on actual hardware: We cycled this cell through repeated draw tests simulating carpet-load suction. The BMS held steady under sustained motor current without triggering a protective cutoff during normal operating draw. Voltage at full charge measured within the expected range for Ni-MH at this capacity.
• Dock charging on the XR210: Do not leave the XR210 sitting on its charging dock permanently. Ni-MH cells on continuous trickle charge degrade faster than those charged only when depleted. Charge the vacuum to full, then remove it from the dock until the next use.

Suction dropping before the battery indicator shows low on the XR210

This happens because the motor voltage sags under load before the cell voltage drops far enough to trigger the indicator. A degraded Ni-MH cell loses internal resistance tolerance first — voltage under draw collapses early, but resting voltage still reads acceptable. The indicator reads resting voltage, not loaded voltage, so it stays green while suction is already weak. A fresh cell at full charge should hold above 13.5V under normal motor load on the XR210.

XR210 motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a dead battery. When the filter is partially blocked, the motor works harder to pull the same airflow — current draw spikes above the BMS threshold and the circuit opens to protect the cell. The vacuum recovers after a short pause because the BMS resets once current normalises. Clean or replace the filter first; if cutouts continue with a clean filter on a new cell, measure resting voltage — it should read at least 14.4V when fully charged.
