It fits the FALTIMA-031, FALTIMA-031B, FALTIMA-031W, and FTM-031K models. The pack matches the OEM voltage and capacity spec at 50.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFALTIMA-031 series compatibility:\u003c\/strong\u003e\n    The 031, 031B, 031W, and FTM-031K all share the same 14.4V battery platform and connector housing. The BMS in each model communicates with the same cell chemistry, so one pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a FALTIMA-031 unit. The BMS accepted the cell handshake, charge current ramped correctly, and the top-of-charge cutoff triggered at the expected threshold with no error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charge behaviour on Ni-MH vacuums:\u003c\/strong\u003e\n    Do not leave the FALTIMA-031 sitting on the charging dock continuously. Ni-MH cells on permanent trickle charge develop capacity fade 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 show voltage sag under load before the pack is actually depleted. On the FALTIMA-031, the motor draws harder against a restricted airflow — blocked filter, full dust cup, or hair wrap on the brush roll — and that extra draw accelerates voltage sag. The indicator reads mid-charge while suction has already dropped noticeably. Clean the filter and empty the cup first; if suction recovers immediately, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and 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 sustained suction restriction — a clogged filter or blockage in the nozzle — forces the motor to draw beyond the BMS current limit, the pack shuts output to protect the cells. The vacuum goes quiet, the BMS resets after a brief thermal pause, and power returns. Fix the restriction first: clear the filter and check the nozzle. If the trip still occurs on a clear airflow path, check pack voltage at rest — a healthy 14.4V Ni-MH pack should read at least 15.6V fully charged.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428042637402,"sku":"BWCS-KSB002VX-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428042670170,"sku":"BWCS-KSB002VX-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428042702938,"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\/gais-faltima-031-replacement-battery-144v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
