It fits ALE-L04, ALE-CL00, ALE-UL00, and over 29 additional ALE-series variants. Dimensions are 97.95 × 41.46 × 3.68mm — matching the original footprint for a direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eALE-series model coverage:\u003c\/strong\u003e\n    All listed ALE variants share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on ALE-L04 hardware. The BMS initialised correctly on first power-up, charge IC accepted the cell without flagging an error, and voltage held within spec across a full discharge cycle under mixed screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into 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 a replacement P8 Lite cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity defect. Under combined modem and display load, the cell voltage drops sharply — the phone's power IC interprets this as a critically low voltage and shuts down before the fuel gauge reaches 0%. It happens most often in the first few cycles on a new cell, when the coulomb counter is still calibrated to the old cell's discharge profile. Running one full discharge to below 5% and a complete charge to 100% at standard rate resets the counter. After that cycle, the reported percentage tracks correctly against actual cell voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after cell replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P8 Lite uses a fuel gauge IC that stores learned discharge data from the previous cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry. The result is percentage jumps, early low-battery warnings, or readings that stall at a fixed number for extended periods. One full discharge-charge cycle at standard rate forces the IC to relearn the curve against the new cell. After that cycle, readings stabilise to within a few percent of actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404145950810,"sku":"BWCS-HUP820SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404145983578,"sku":"BWCS-HUP820SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404146016346,"sku":"BWCS-HUP820SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUP820SL-1.webp?v=1779369080","url":"https:\/\/batteryweb.com\/products\/huawei-p8-lite-replacement-battery-38v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
