It replaces OEM part LC-620, the original cell that powers the display, processor, modem, and all onboard functions. Order this when the existing cell no longer holds charge through a normal day or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNokia 6.2 fitment:\u003c\/strong\u003e\n    The Nokia 6.2 uses the LC-620 cell format — 77.80 × 62.60 × 3.90mm with a specific connector pinout that carries battery ID and temperature data to the phone's power management IC. A mismatched cell triggers a battery warning or refuses to charge.\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 the Nokia 6.2 platform. The BMS handshake completed without error flags, charge current ramped correctly through CC\/CV phases, and the fuel gauge IC accepted the new cell without tripping a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge down to auto-shutdown, then charge to 100% on standard current. This gives the fuel gauge IC a full reference curve for the new cell before high-current fast charging is applied to an uncalibrated state.\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 6.2 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia 6.2 uses a coulomb counter combined with a voltage-based fuel gauge IC. That IC builds its percentage model against the discharge curve of the original cell over hundreds of cycles. When a new cell goes in, the stored curve no longer matches the actual cell behaviour — so the reported percentage drifts from reality. The fix is one full uninterrupted discharge-to-shutdown followed by a full charge with the screen on, which forces the IC to re-map its curve against the new cell. After that single cycle, percentage reporting stabilises.\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 recalibrated and the phone hits a voltage cliff — the cell voltage drops below the modem's or display's minimum rail before the gauge registers low charge. Under peak load, a fresh uncalibrated cell can sag from a reported 25% straight to the hardware cutoff voltage of around 3.2V. The phone interprets this as an emergency shutdown, not a low-battery event. Run the first-cycle recalibration process above and the cliff moves back to its correct position near 5–8%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391948062810,"sku":"BWCS-NKT620SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391948095578,"sku":"BWCS-NKT620SL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391948128346,"sku":"BWCS-NKT620SL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKT620SL-1.webp?v=1779142720","url":"https:\/\/batteryweb.com\/products\/nokia-62-replacement-battery-385v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
