It restores the Furtiv's ability to run full autonomous cleaning cycles after the original cell pack has faded. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFurtiv platform fit:\u003c\/strong\u003e\n    The Furtiv uses a self-contained 14.4V Ni-MH pack with a fixed connector and BMS that monitors cell voltage during discharge. This replacement matches that voltage rail and connector format so the vacuum's onboard electronics accept it without throwing a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through charge and discharge cycles on the bench. The BMS held cutoff at the correct low-voltage threshold and the charge circuit accepted a full charge without flagging an incompatibility error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the Furtiv:\u003c\/strong\u003e\n    Do not leave the Furtiv sitting on the charging dock permanently. Ni-MH cells on continuous trickle charge develop capacity fade faster than cells charged only when depleted. Charge the battery to full, then remove the vacuum from the dock until the next cleaning session.\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 sag that the Furtiv's indicator circuit doesn't always catch immediately. When the motor draws current against a partially blocked filter or thick carpet, cell voltage dips below the level needed to sustain full suction — even though the indicator still shows charge remaining. The motor gets less voltage, so suction output drops noticeably. Clean or replace the filter first, then retest; if suction holds steady after that, the filter was the cause, not the battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-cycle and then recovering on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the Furtiv's suction path is restricted — blocked filter, tangled brush roll, or a carpet pile the inlet is fighting against — the motor draws sustained current above the BMS trip threshold. The BMS disconnects the cell pack to protect the cells, the motor stops, and after a few seconds the BMS resets and allows restart. Clear the blockage and check that the filter is clean before running another cycle. If the cutout stops after that, the BMS was doing its job correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428042440794,"sku":"BWCS-KSB002VX-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428042473562,"sku":"BWCS-KSB002VX-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428042506330,"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\/eziclean-furtiv-replacement-battery-144v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
