It replaces the original battery when the cell has degraded, lost capacity, or will no longer hold a charge. Dimensions are 75.10 × 63.50 × 3.80mm — verify clearance before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLe 2 and Le 2 Pro compatibility:\u003c\/strong\u003e\n    Both models run the same battery bay dimensions and voltage rail. The connector pinout and BMS handshake are identical across the two variants, so one cell covers both.\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 Le 2 platform. The BMS accepted the new cell without error flags, and charge termination triggered correctly at 4.35V under standard charge protocol.\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 full 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\"\u003eWhy the Le 2 shuts down suddenly at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Le 2 uses a coulomb counter that was calibrated against the discharge curve of the original cell. A new cell has a slightly different voltage-to-capacity curve, so the fuel gauge misreads remaining capacity. Under high load — screen at full brightness, LTE active, background sync running — the cell voltage drops faster than the gauge expects. The phone hits the hardware shutdown threshold before the OS percentage reaches zero. One full discharge-charge cycle without fast charging resets the calibration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not working on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLeEco's proprietary charge protocol requires the charge IC to verify cell impedance before stepping up current. On a brand-new cell, impedance reads higher than a conditioned cell, and the IC falls back to standard 5V charging as a precaution. This is not a fault — it resolves after the first complete cycle. Complete one full discharge to around 5% and charge back to 100% at standard rate, then fast charging re-enables on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392091127898,"sku":"BWCS-LTX620SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392091160666,"sku":"BWCS-LTX620SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392091193434,"sku":"BWCS-LTX620SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTX620SL-1.webp?v=1779143685","url":"https:\/\/batteryweb.com\/products\/leeco-le-2-replacement-battery-383v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
