It replaces OEM part HB366179ECW using the same connector and footprint as the factory cell. Install when the original cell no longer holds charge, shuts down unexpectedly, or has physically swollen.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNova 2 and Dual SIM variant fit:\u003c\/strong\u003e\n    The PIC-TL00 and PIC-AL00 share the same battery bay geometry, flex connector pinout, and BMS handshake protocol. One cell fits both board revisions without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Nova 2 unit, confirmed the BMS handshake completed correctly, and verified the charge IC accepted the cell through a full charge cycle without fault flags.\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-to-charge cycle at standard current. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC applies high-current Huawei SuperCharge protocols 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\"\u003eSudden shutdown at 20–30% on the Nova 2 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nova 2 uses a coulomb counter in the PMIC that was calibrated against the discharge curve of the original cell. A new cell with a slightly different internal resistance profile hits a voltage cliff under modem or display load that the old calibration data did not anticipate. The PMIC sees the voltage drop as a critical low-battery event and cuts power even though the cell has charge remaining. One full discharge-charge cycle at standard current rewrites the reference table and stops the early cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHuawei SuperCharge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSuperCharge negotiation happens between the charge IC and the charger at the USB port — but the BMS on a new cell runs an internal impedance check before it allows high-current input. On the first cycle, a fresh cell with slightly elevated impedance can cause the BMS to hold current below the SuperCharge threshold, so the phone charges at standard 5V\/2A instead. This is not a charger fault or a cable fault. Complete one full standard-rate charge cycle first, then reconnect the SuperCharge adapter — impedance drops after the first cycle and the protocol negotiation completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392067895386,"sku":"BWCS-HUN200XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392067928154,"sku":"BWCS-HUN200XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392067960922,"sku":"BWCS-HUN200XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUN200XL-1.webp?v=1779143561","url":"https:\/\/batteryweb.com\/products\/huawei-nova-2-replacement-battery-385v-2950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
