Klarstein 210XR Cordless Vacuum Replacement Battery 14.4V

Klarstein 210XR / Cleantouch KV8 210C — 14.4V Ni-MH Replacement Battery

This is a 14.4V 2000mAh Ni-MH replacement battery pack for the Klarstein 210XR and Cleantouch KV8 210C cordless vacuum range. It fits directly into the battery compartment of these handheld stick vacs and restores motor power to the suction system. Replace when the original pack no longer holds a useful charge between cleans.

• 210XR and KV8 210C platform fitment: These models share the same 14.4V motor rail, battery slot geometry, and connector pinout — one pack covers the full range listed above without modification.
• Bench tested on actual hardware: We ran discharge cycles through the vacuum's motor circuit and confirmed the BMS holds voltage within spec under sustained suction load. No premature cutoff was triggered during normal operating draw.
• Dock charging on these vacuums: Remove the Klarstein from its charging dock once the pack reaches full charge. Ni-MH cells in continuous dock contact receive a trickle current that accelerates capacity loss — charge only when depleted, then disconnect.

Suction dropping before the battery indicator reaches low

On the Klarstein 210XR, suction loss mid-session usually isn't a flat battery — it's motor voltage sag caused by a restricted filter forcing the motor to draw above its rated current. The BMS reads that elevated draw as a low-cell event and throttles output to protect the pack. Clean or replace the filter first, then retest. If suction holds steady after that, the battery was never the problem.

Motor cutting out completely, then recovering after a short pause

This is a BMS overcurrent trip — not a dying battery. When airflow through the 210XR is restricted by a blocked filter or a blockage in the nozzle, sustained high current triggers the BMS protection circuit, which shuts the motor off. The pack recovers once current demand drops. Clear the blockage, wait 30 seconds, then restart. If the cutout repeats on a clear nozzle, measure pack voltage under load — a healthy cell should hold above 12V during motor run.
