These are early-2000s candybar phones used for basic voice and messaging. Install this cell when the original no longer holds enough charge for a full day of normal standby and calling use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — 1220, 1221, 1260, 1261 and more:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pin layout, and 3.7V single-cell architecture. The BLC-2, BLC-1, and BMC-3 part numbers are interchangeable across this platform — Nokia standardised the footprint across multiple handset variants in this generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Nokia 1260 and monitored charge termination. The cell accepted a full charge from the original Nokia desk charger without thermal runaway, and the protection circuit tripped correctly at the low-voltage cutoff threshold during a controlled deep discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    Run one complete discharge-to-charge cycle before relying on the battery indicator. The phone's fuel gauge IC was calibrated to your old, degraded cell. One full cycle lets it re-map the discharge curve against the new cell and report accurate charge levels.\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 1260 shuts off suddenly while the indicator still shows charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the original cell has aged to the point where its internal resistance spikes sharply under load. Even with the indicator showing 20–30% remaining, the cell voltage collapses below the shutdown threshold the moment the modem draws current during a call. The phone's protection circuit reads this as a fault and cuts power immediately. A new cell with lower internal resistance sustains voltage under that same load, eliminating the mid-use cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after sitting in a drawer for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the original battery dropped below approximately 2.5V, the battery's protection circuit locked out to prevent damage — and the phone will not respond to a charger or the power button. Connect the phone to a charger and leave it for at least 30–60 minutes without pressing anything; some chargers trickle current into a locked-out cell and slowly recover it above the re-enable threshold. If the original cell does not recover past 3.0V, it will not hold a stable charge and replacement is the correct fix.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409484185690,"sku":"BWCS-NKC2MH-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409484218458,"sku":"BWCS-NKC2MH-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409484251226,"sku":"BWCS-NKC2MH-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKC2MH-1.webp?v=1779579815","url":"https:\/\/batteryweb.com\/products\/nokia-1220-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
