It slots in when the original cell can no longer hold a useful charge, restoring the vacuum's ability to complete a full cleaning cycle. Capacity figure is taken from the product specification — not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE.Ziclean Furtiv and Swr22 compatibility:\u003c\/strong\u003e\n    Both models run on the same 14.4V battery platform and share an identical connector footprint and BMS voltage threshold, which is why a single replacement cell covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the bench and confirmed the BMS communicates correctly with the charger — charge acceptance was normal and the protection circuit tripped cleanly at the low-voltage cutoff threshold without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on robotic vacuums:\u003c\/strong\u003e\n    Do not leave the E.Ziclean Furtiv sitting on the dock between uses permanently. Continuous trickle charge from the dock degrades Ni-MH cells faster than scheduled charge cycles. Charge to full, then remove the unit from the dock until the next run.\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\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells in robotic vacuums show voltage sag under motor load before the pack is actually depleted. When the filter is partially blocked, the motor draws above its rated current and the pack voltage drops sharply, triggering the low-power threshold early. The vacuum then reduces suction or returns to dock even though the cell has remaining capacity. Clean or replace the filter first — if suction holds after that, the battery was not the problem.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-run and then recovering after a short pause\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the intake is restricted — blocked brush roll, clogged filter, or the unit pressed against a wall — the motor pulls sustained high current and the protection circuit shuts the output to prevent cell damage. The pack recovers once current draw drops, so the unit powers back on. Clear the restriction, confirm the brush roll spins freely, then restart — the cut-out should not repeat on an unobstructed run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428043358298,"sku":"BWCS-KSB002VX-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428043391066,"sku":"BWCS-KSB002VX-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428043423834,"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\/nestor-eziclean-furtiv-replacement-battery-144v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
