The original cell degrades over charge cycles, causing capacity loss, erratic percentage readings, and unexpected shutdowns. This replacement restores the phone to a functional power state.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV3760T and C2 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions (79.84 × 63.10 × 4.30mm), voltage rail at 3.8V nominal, and connector pinout — one cell fits both without modification.\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 discharge cycles on a V3760T unit. The BMS accepted the charge handshake correctly, and the protection circuit tripped cleanly at low-voltage cutoff without requiring manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging runs against an uncalibrated coulomb counter.\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 a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell in an old phone often triggers shutdowns well above 0% because the fuel gauge IC still holds the discharge curve of the degraded original battery. Under modem activity or screen-on load, voltage dips faster than the stale curve predicts, and the system cuts power before the gauge reaches zero. The fix is a full supervised discharge to 3.2–3.3V under normal use, followed by a full charge — this forces the coulomb counter to resync to the new cell's actual capacity. After one complete cycle, the reported percentage stabilises and early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB charging accepted but percentage stays at 0% after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the phone sat discharged for weeks or months, the cell voltage may have dropped below 2.5V per cell — the BMS lockout threshold. Below that point, the protection circuit opens the discharge path and the phone appears completely dead even when plugged in. Most chargers won't negotiate past the BMS in this state. Connect the phone via USB to a powered PC rather than a fast charger, leave it for 20–30 minutes at low current trickle, and the BMS will recover once cell voltage climbs back above the 2.5V floor — the phone should then boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391934070874,"sku":"BWCS-NKV376SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391934103642,"sku":"BWCS-NKV376SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391934136410,"sku":"BWCS-NKV376SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKV376SL-1.webp?v=1779142678","url":"https:\/\/batteryweb.com\/products\/nokia-v3760t-replacement-battery-38v-2700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
