It fits the Vodafone Smart III, Smart 3, 975N, and VF975 smartphones. Swap it in when the original cell no longer holds enough charge to get through a day of calls, messaging, and app use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmart III \/ VF975 platform fit:\u003c\/strong\u003e\n    The 975N, VF975, and Smart 3 all share the same battery bay dimensions and connector pinout as the Smart III. The TLi015A1 part number spans that entire family — one cell, one BMS handshake, same 3.7V nominal rail across every variant.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a Smart III unit. The BMS accepted the charge profile without fault flags, held voltage within spec at load, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging is applied to an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Smart III after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Smart III's fuel gauge IC stores a discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. Under modem load — during a call or mobile data burst — the phone draws current the old curve didn't predict, voltage sags below the cutoff threshold, and the BMS shuts the device down even though the OS still shows charge remaining. One full discharge-charge cycle without fast charging lets the coulomb counter reset against the new cell's real curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone feels warm near the battery during the first charge after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell comes from storage with higher internal impedance than a conditioned cell. The charge IC on the Smart III pushes current into that higher-resistance cell, and the additional heat is a normal first-cycle effect. It should not persist beyond the first full charge. If the device stays warm through a second complete charge cycle, check that the back cover is seated flat — any gap that holds the cover away from the cell reduces heat dissipation and can trap warmth longer than expected. Normal operating temperature for the cell is below 45°C at the surface.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404255690842,"sku":"BWCS-OT975XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404255723610,"sku":"BWCS-OT975XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404255756378,"sku":"BWCS-OT975XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT975XL-1.webp?v=1779369511","url":"https:\/\/batteryweb.com\/products\/vodafone-smart-iii-replacement-battery-37v-1650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
