It fits the same battery bay and connector as the factory unit. Use the Capacity figure above — 850mAh — as the reference spec for this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN110, N118, N650i, N342i compatibility:\u003c\/strong\u003e\n    These four models share the same 3.7V single-cell architecture and the same physical connector pinout. One replacement cell covers the full group — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench. The BMS accepted a standard CC\/CV charge profile, held voltage within spec under simulated call and screen load, and triggered cutoff cleanly at the lower voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge to auto-shutoff, then charge uninterrupted to 100% before using the phone normally. This lets the fuel gauge IC map its coulomb counter to the new cell's actual discharge curve and stops erratic percentage readings early on.\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 NEC N110 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a slightly different internal resistance profile than the aged original. When the phone's modem fires up for a call or the screen peaks brightness, current draw spikes. If the fuel gauge IC is still calibrated to the old cell's curve, it misreads available voltage and the phone shuts down even though the reported percentage looks safe. The fix is one full discharge-charge cycle with no interruptions — this resets the coulomb counter baseline. After that cycle, shutdowns at 20–30% typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone shows incorrect battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on these NEC models learns the cell's discharge curve over time. Fit a new cell and it still references the old curve — so percentage readings jump, stall, or drop suddenly in the last quarter. This is a calibration state, not a fault with the cell. Drain the phone fully until it powers off on its own, then charge it to 100% in one session. The IC recalibrates against the new curve and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405173293146,"sku":"BWCS-NEN650SL-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405173325914,"sku":"BWCS-NEN650SL-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405173358682,"sku":"BWCS-NEN650SL-3","price":28.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NEN650SL-1.webp?v=1779370333","url":"https:\/\/batteryweb.com\/products\/nec-n110-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
