It fits directly into the XR-210 and powers the motor and suction system. When the original pack no longer holds a useful charge, this cell restores the vacuum to working condition.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXR-210 platform fit:\u003c\/strong\u003e\n    The XR-210 runs a 14.4V Ni-MH architecture with a fixed connector and BMS calibrated to Ni-MH charge curves. This replacement matches that voltage rail and chemistry, so the charger and BMS communicate correctly without triggering a false fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the XR-210 platform. The BMS accepted the cell without error, current draw at motor start sat within expected range, and the pack held voltage under continuous suction load without dropping out prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the XR-210:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock once the pack reaches full charge. The XR-210 dock does not cut trickle current automatically — leaving it connected keeps a low current running through the Ni-MH cells, which accelerates capacity fade over weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is not always a battery problem. On the XR-210, a partially blocked filter forces the motor to draw more current than rated to maintain airflow. That extra draw causes the pack voltage to sag earlier than it would under a clean load. The BMS reads the voltage drop as a low-battery condition and reduces power to protect the cells. Clear the filter first — if suction holds longer after that, the battery was not the root cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out briefly then recovers during use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe XR-210 BMS has an overcurrent trip that activates when sustained current draw exceeds the pack's rated threshold. This usually happens when suction is restricted — a blocked nozzle or saturated filter makes the motor work harder and pull more amps than the BMS allows. The pack trips, cools for a few seconds, then resets. Fix the restriction first. If the cutout continues on a clean, unobstructed vacuum, check that the replacement cell voltage reads at least 14.4V on a multimeter after a full charge before assuming the pack is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428043653210,"sku":"BWCS-KSB002VX-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428043685978,"sku":"BWCS-KSB002VX-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428043718746,"sku":"BWCS-KSB002VX-3","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KSB002VX-1.webp?v=1779933966","url":"https:\/\/batteryweb.com\/products\/roreland-xr-210-replacement-battery-144v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
