It fits the WLZ-AL10 and WLZ-AN00 variants and carries OEM part numbers HB446589EEW and HB446589EEC. Install it when the original cell no longer holds charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNova 6 WLZ-AL10 and WLZ-AN00 compatibility:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol, so one cell covers both boards without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge cycles on a Nova 6 board and confirmed the BMS accepted the charge IC handshake, held the 4.40V charge ceiling, and triggered protection cutoff correctly at the low-voltage threshold.\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 and run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on 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 Nova 6 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nova 6's fuel gauge IC retains the discharge curve of the old, degraded cell after a swap. When the new cell's open-circuit voltage drops into a range the IC was not expecting, it reports a false low-state and triggers a protective shutdown. The modem and display together pull enough current at that state of charge to cause a voltage sag the IC interprets as a dead cell. One full discharge-charge cycle — without fast charging — resets the coulomb counter and clears the mismatch.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not recognised on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHuawei's proprietary fast-charge protocol requires the charge IC and BMS to complete a handshake before high-current delivery is authorised. On a fresh cell the BMS may not respond to the fast-charge negotiation until it has completed one standard charge cycle. Plug into a 5V standard charger, let it charge fully, then reconnect the fast charger. If the phone still refuses the protocol, check that the flex connector is fully seated — a partial connection interrupts the BMS communication line.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391986729050,"sku":"BWCS-HUN600SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391986761818,"sku":"BWCS-HUN600SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391986794586,"sku":"BWCS-HUN600SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUN600SL-1.webp?v=1779142720","url":"https:\/\/batteryweb.com\/products\/huawei-nova-6-replacement-battery-385v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
