It fits the Elite Y directly and matches the original voltage and connector spec. Capacity is rated at 8.74Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElite Y compatibility:\u003c\/strong\u003e\n    The Elite Y uses a fixed 3.8V single-cell Li-ion architecture. This replacement matches that voltage rail and the original BMS handshake requirements so the phone's charge IC recognises the cell on first boot.\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 sequences and monitored the BMS cutoff behaviour at both the high-voltage ceiling and the low-voltage floor. Cutoff triggers held within spec at both ends.\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 is applied to an uncalibrated cell.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell has a steeper voltage drop under modem and screen load than the degraded original. The phone reads 25% on the old curve but the actual cell voltage has already crossed the BMS cutoff threshold. One full discharge-charge cycle with fast charging disabled forces the coulomb counter to reset against the real curve and eliminates the false-floor shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after sitting in storage at low charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored below roughly 2.5V trigger a BMS lockout to prevent damage from over-discharge. The phone will show no response to the power button. Connect the phone to a wall charger — not a PC USB port — and leave it for 15–20 minutes without pressing anything. The charge IC trickle-charges the cell back above the BMS re-enable threshold, after which normal boot resumes. If the screen stays dark past 30 minutes on the charger, check the charging cable and adapter output voltage first.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392033554522,"sku":"BWCS-LGE100SL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43392033587290,"sku":"BWCS-LGE100SL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43392033620058,"sku":"BWCS-LGE100SL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LGE100SL-1.webp?v=1779143030","url":"https:\/\/batteryweb.com\/products\/leagoo-elite-y-replacement-battery-38v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
