It slots into the battery bay where the original cell sits, restoring power to calling, messaging, and app functions. Swap it in when the original battery no longer holds a useful charge or swells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN1, N1-Y, and N1-T compatibility:\u003c\/strong\u003e\n    These three variants share the same chassis dimensions and 3.8V power rail, which means the same cell geometry — 83.40 × 61.90 × 3.50mm — fits all three without modification. The connector pinout and BMS handshake are consistent across the N1 family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the N1 platform. The BMS accepted the charge IC handshake cleanly, and the protection circuit tripped at the correct low-voltage cutoff without false positives under screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes into 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 Green Orange N1 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe N1's fuel gauge IC builds its percentage model from the previous cell's charge curve, stored in memory. When a new cell goes in, the IC still references the old curve, so the displayed percentage drifts from actual capacity. The fix is one full uninterrupted discharge down to automatic shutdown, followed by a full charge without interruption. After that cycle, the coulomb counter resets against the new cell's actual curve and percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff issue, not a capacity issue. Under combined modem and display load, the cell voltage sags faster than the fuel gauge IC predicts — the phone hits the hardware low-voltage cutoff before the percentage reaches zero. It happens most often in the first few cycles when the gauge IC is still recalibrating. Run two full discharge-charge cycles and the shutdowns typically stop once the IC learns the actual voltage-to-capacity relationship. If it persists after three full cycles, check that the cell connector is fully seated — a loose contact increases resistance and accelerates voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404228821082,"sku":"BWCS-GSG110SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404228853850,"sku":"BWCS-GSG110SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404228886618,"sku":"BWCS-GSG110SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GSG110SL-1.webp?v=1779369391","url":"https:\/\/batteryweb.com\/products\/green-orange-n1-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
