It carries OEM part number HQ510 and fits the Nokia 2.2 directly. Swap it when the original cell no longer holds a charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNokia 2.2 (2019) fitment:\u003c\/strong\u003e\n    The Nokia 2.2 uses a single-cell Li-Polymer pack at 3.85V nominal. The HQ510 matches the connector pinout, cell dimensions (73.60 × 59.80 × 4.76mm), and BMS communication expected by the phone's charge IC — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and load cycles on compatible Nokia 2.2 hardware. The BMS accepted the charge IC handshake without fault flags, and the cell held voltage within spec under sustained screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first cycle after installation, disable fast charging and let the phone run from 100% down to automatic shutdown, then charge uninterrupted to full. This gives the Nokia 2.2's fuel gauge IC one complete reference curve against 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\"\u003eWhy the Nokia 2.2 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia 2.2 uses a coulomb counter and voltage-curve model to estimate state of charge. That model was trained on the old cell's discharge curve. A new HQ510 cell has a slightly different internal resistance and voltage profile, so the OS reads the wrong percentage until it maps a fresh curve. One full discharge-to-shutdown followed by an uninterrupted full charge resets the reference. After that cycle, percentage readings stabilise.\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 calibrated to the new cell's voltage cliff — the point where cell voltage drops sharply under modem or display load. The phone's protection circuit reads that voltage dip as a low-cell event and cuts power before the displayed percentage reaches zero. It is not a faulty cell. Run one full discharge cycle without fast charging, then charge to 100%. If shutdowns persist past the second cycle, check that the battery flex connector is fully seated — a loose contact raises apparent internal resistance and triggers the same cutoff at around 3.5V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391945080922,"sku":"BWCS-NKT220SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391945113690,"sku":"BWCS-NKT220SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391945146458,"sku":"BWCS-NKT220SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKT220SL-1.webp?v=1779142677","url":"https:\/\/batteryweb.com\/products\/nokia-22-replacement-battery-385v-2900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
