It replaces OEM part numbers HE319 and HE330, which Nokia used across that model range. Physical dimensions are 68.50 × 59.80 × 4.00mm, matching the original cell envelope.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNokia 3 variant coverage:\u003c\/strong\u003e\n    The TA-1020, TA-1028, and TA-1032 are regional SKUs of the same Nokia 3 hardware platform. They share the same battery bay geometry, connector pinout, and charge IC handshake — so one cell covers 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 on the Nokia 3 platform and tracked BMS communication through a full charge cycle. The protection circuit responded correctly to the MediaTek charge IC — charge termination triggered at 4.35V and cutoff engaged at 3.0V under load, consistent with OEM spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. The Nokia 3 uses a coulomb-counter-based fuel gauge that is still calibrated to the old cell's discharge curve. One full cycle at standard current lets it remap to the new cell 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\"\u003eSudden shutdown at 20–30% on the Nokia 3 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. A fresh lithium-polymer cell has a steeper voltage-discharge curve than a worn cell, so the fuel gauge IC underestimates remaining charge and triggers a low-voltage shutdown earlier than expected. The MediaTek SoC in the Nokia 3 pulls high current during LTE transmission bursts, which causes momentary voltage sag that the uncalibrated gauge misreads as a near-empty cell. Run two full discharge-charge cycles at standard charge rate and the shutdowns will stop as the coulomb counter aligns to the new cell curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNokia 3 reporting wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia 3's fuel gauge IC stores learned capacity data from the original cell. After a cell swap, that stored data no longer matches the new cell's actual discharge profile, so the percentage readout drifts — often showing 50% then jumping to 15% within minutes. This is not a fault with the replacement cell. Charge the phone to 100% using the standard charger, use it until it shuts down on low battery, then charge back to 100% without interruption. After that single full cycle, the coulomb counter resets its reference and percentage accuracy returns.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392050921562,"sku":"BWCS-NKT102SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392050954330,"sku":"BWCS-NKT102SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392050987098,"sku":"BWCS-NKT102SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKT102SL-1.webp?v=1779143526","url":"https:\/\/batteryweb.com\/products\/nokia-nokia-3-replacement-battery-385v-2600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
