It fits the stock battery bay without modification and reconnects to the same flex connector as the factory cell. Capacity is rated at 11.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHonor 6 variant coverage:\u003c\/strong\u003e\n    The H60-L02, H60-L04, and Mulan share the same battery bay dimensions and connector pinout — same voltage rail, same BMS handshake protocol. One cell fits all of them without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an Honor 6 unit and confirmed the BMS accepted the handshake on first boot. Charge IC communicated correctly with the replacement cell and reported state-of-charge without prompting a fault code.\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 pushes current into an uncalibrated cell — skipping this step is the main cause of erratic percentage readings.\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 Honor 6 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Honor 6's fuel gauge IC stores a discharge curve calibrated to the original cell. After a cell swap, that stored curve no longer matches the new cell's actual voltage-versus-capacity profile. When the modem fires or the screen hits full brightness, current draw spikes and the new cell's voltage drops below the shutdown threshold — even though the reported percentage still shows 20–30%. The fix is one full discharge-charge cycle with fast charging disabled, which forces the coulomb counter to rebuild its curve against the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage, and if the replacement cell drops below 2.5V, the BMS enters lockout to prevent damage. The Honor 6 will show no response to the power button — not even a charging indicator on first plug-in. Connect the phone to a charger and leave it for 20–30 minutes without pressing anything; the charge IC trickle-charges the cell back above the BMS re-initialisation threshold, typically around 2.8–3.0V, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404261883994,"sku":"BWCS-HUR600SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404261916762,"sku":"BWCS-HUR600SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404261949530,"sku":"BWCS-HUR600SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUR600SL-1.webp?v=1779369511","url":"https:\/\/batteryweb.com\/products\/huawei-honor-6-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
