It matches the original WT240 specification at 3.85V nominal voltage. Swap it in when the original cell no longer holds a usable charge through a full day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNokia 3.2 variant coverage:\u003c\/strong\u003e\n    The TA-1154, TA-1156, and TA-1159 share the same physical cell footprint, connector pinout, and BMS communication protocol — one battery fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Nokia 3.2 unit. The BMS accepted the handshake without fault codes, and the charge IC stepped through trickle, CC, and CV phases as expected on first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and complete one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell's discharge curve before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nokia 3.2 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia 3.2 uses a coulomb-counter-based fuel gauge IC that builds its charge model against the original cell's impedance and discharge curve. When you install a new cell, the IC still references the old curve, so reported percentage drifts from actual state-of-charge. The gauge recalibrates itself over one to three complete discharge-charge cycles. After the first full cycle from 100% down to auto-shutdown and back to 100%, percentage reporting tightens noticeably.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet mapped the new cell's voltage-to-capacity curve. Under load — screen at full brightness, mobile data active, or a call in progress — the cell voltage drops sharply at the low end of charge, hitting the BMS undervoltage cutoff before the OS registers a low-battery warning. It is not a faulty cell. Complete two full discharge-charge cycles and the gauge learns where the voltage cliff sits. If shutdowns persist past three cycles, check that the cell connector is fully seated — a partial connection raises contact resistance and amplifies voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391989645402,"sku":"BWCS-NKT115SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391989678170,"sku":"BWCS-NKT115SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391989710938,"sku":"BWCS-NKT115SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKT115SL-1.webp?v=1779142762","url":"https:\/\/batteryweb.com\/products\/nokia-32-replacement-battery-385v-3950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
