It fits directly in place of the original cell pack when the factory battery no longer holds enough charge to complete a cleaning cycle. Capacity is 2000mAh (28.8Wh), matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e210C and 210XR platform fit:\u003c\/strong\u003e\n    Both models run the same 14.4V cell architecture and use the same connector and housing dimensions — 91.91 × 67.35 × 44.58mm. Either model accepts this battery without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through repeated charge and discharge runs on the 210C platform. The BMS handled motor-start current draw without tripping, and the cell pack reached rated capacity across multiple cycles before being cleared for stock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on this vacuum:\u003c\/strong\u003e\n    Do not leave the 210C sitting on the charging dock permanently. Continuous trickle charge from the dock degrades Ni-MH cells faster than deliberate charge cycles. Charge to full, then remove the vacuum from the dock until the next use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the battery can sustain at its present state of charge, causing voltage to sag under load. A partially clogged filter makes this worse — the motor works harder against restricted airflow, pulling more amps and accelerating the sag. The vacuum's power stage throttles back to protect the motor, which the user feels as a loss of suction. Clean the filter first, then check whether the issue persists with a freshly charged battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure. When suction is restricted — blocked filter, full dustbin, or a jam at the nozzle — the motor draws sustained current above the BMS threshold. The BMS cuts power to protect the cells, then resets once current demand drops. Clear any blockage and empty the dustbin, then restart. If the cutout continues on a clear airpath, verify the battery rests above 12.5V at idle before concluding the cell pack is the cause.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428068229210,"sku":"BWCS-KSB001VX-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428068261978,"sku":"BWCS-KSB001VX-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428068294746,"sku":"BWCS-KSB001VX-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KSB001VX_1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/kv8-210c-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
