It slots into the battery bay and powers the motor, navigation, and brush systems. Fit the replacement when the original cell no longer holds enough charge to complete a cleaning cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE.Ziclean Furtiv and H.Koenig Swr22 compatibility:\u003c\/strong\u003e\n    Both units share the same 14.4V battery bay, connector pinout, and BMS handshake logic, which is why one cell covers both models. The voltage rail and physical footprint — 91.91 x 67.35 x 44.58mm — are identical across the two platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated charge and discharge runs on the E.Ziclean Furtiv chassis. The BMS accepted the cell without error flags, and the motor and brush deck drew current within the expected operating range throughout each run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Ni-MH cells on continuous trickle charge develop capacity fade significantly faster than cells charged only when depleted. Charge to full, then remove from the dock.\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\"\u003eNi-MH cells under load show a voltage curve that drops steeply once the cell is past roughly 70% depletion. The E.Ziclean Furtiv's motor controller reads that sag as insufficient supply and reduces brush and fan speed before the indicator circuit registers a low-battery state. A clogged filter compounds the problem — restricted airflow forces the motor to draw harder, which accelerates the voltage drop. Clean the filter first, then confirm the replacement cell is reading above 14.0V at rest before docking it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the brush roll hits a dense patch of carpet or a partial blockage, current draw spikes and the BMS opens the circuit to protect the cell. After a few seconds the BMS resets and the motor restarts. The fix is to clear any debris wrapped around the brush roll and check that the filter is not blocked — both conditions push sustained current draw above the BMS trip threshold. If the cutout persists on a clean machine, the original cell's internal resistance has likely risen high enough that it can no longer supply peak motor-start current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428068098138,"sku":"BWCS-KSB001VX-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428068130906,"sku":"BWCS-KSB001VX-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428068163674,"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\/nestor-eziclean-furtiv-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
