It replaces the original cell when the phone shuts down unexpectedly, no longer holds a charge, or swells. Capacity is 17.19Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEDI-AL10 and Note 8 variant coverage:\u003c\/strong\u003e\n    All listed variants — Standard Edition, Premium, and EDI-AL10 — share the same battery bay dimensions (103.40 × 71.10 × 3.50 mm), connector pinout, and BMS handshake protocol. One cell fits the full range without modification.\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 EDI-AL10 platform. The BMS accepted charge current normally, protection circuits triggered correctly at low-voltage cutoff, and the fuel gauge IC tracked state-of-charge without error flags after a full calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge handling:\u003c\/strong\u003e\n    On first use after installation, disable Huawei's SuperCharge protocol for one complete discharge-charge cycle. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — preventing premature percentage drops mid-session.\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 Note 8 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Honor Note 8's large 6.6-inch display and modem draw significant current spikes. A new cell's internal impedance differs slightly from the aged cell the fuel gauge IC was calibrated against. Under load, the voltage drops faster than the coulomb counter predicts, triggering a low-voltage protection cutoff before the displayed percentage reaches zero. One full discharge-to-3.50V and slow recharge cycle recalibrates the IC and eliminates the false cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuperCharge not activating on the first charge after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHuawei's SuperCharge handshake requires the charge IC to confirm cell voltage is within a valid acceptance window before switching to high-current mode. On a new cell coming out of storage, resting voltage may sit below the threshold the charger expects. Plug in via the stock cable, allow a standard 5V trickle charge to bring the cell above 3.65V, then unplug and reconnect — the SuperCharge handshake will complete on the second connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392088866906,"sku":"BWCS-HUN800SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392088899674,"sku":"BWCS-HUN800SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392088932442,"sku":"BWCS-HUN800SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUN800SL-1.webp?v=1779143685","url":"https:\/\/batteryweb.com\/products\/huawei-honor-note-8-replacement-battery-382v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
