It fits the FALTIMA-031, FALTIMA-031B, FALTIMA-031W, and FTM-031K models. When the original pack loses capacity or stops holding charge, this unit restores full motor voltage to the vacuum.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFALTIMA-031 series fit:\u003c\/strong\u003e\n    All listed variants share the same 14.4V voltage rail, physical connector, and BMS handshake. The cell count and pack geometry are identical across the 031, 031B, 031W, and FTM-031K, so one replacement covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full discharge and charge sequences on a FALTIMA-031 unit. The BMS accepted the handshake on first connection, and the motor drew current at the expected 14.4V nominal without triggering overcurrent cutoff under sustained load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave the FALTIMA-031 sitting on the charging dock continuously. Cordless vacuums on permanent dock charge develop capacity fade significantly faster than units 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\"\u003eCordless vacuum losing suction before battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the FALTIMA-031, suction loss under a partially blocked filter appears before the battery indicator signals low. The motor has to work harder against restricted airflow, drawing higher current than the BMS expects at that state of charge. Voltage at the motor terminals sags under that elevated load even when the pack still reads mid-charge. Clear the filter and check the brush roll for hair wrap before assuming the battery is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean 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 FALTIMA-031 motor sustains a restricted airflow condition — blocked filter, tangled brush roll, or carpet pile jammed against the intake — current draw spikes and the BMS cuts the output to protect the cells. After the pack cools slightly, the BMS resets and the motor restarts. Fix the restriction first; if the cutoff continues on a clear filter with a fresh pack, check that the motor assembly is not binding mechanically. Normal operating current at 14.4V should not be enough to trip the BMS on an unobstructed clean surface.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428068786266,"sku":"BWCS-KSB001VX-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428068819034,"sku":"BWCS-KSB001VX-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428068851802,"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\/gais-faltima-031-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
