Huawei HB386589ECW is a lithium-polymer (Li-Po) rechargeable battery used as the original/OEM power source in several Huawei and Honor mid-range smartphones.
This is a high-capacity Li-Po cell designed for all-day battery life in mid-range Huawei/Honor devices from around 2017–2019. It delivers stable voltage output and supports the fast-charging protocols of the host phones (e.g., 18W on Mate 20 Lite or up to 22.5W SuperCharge on Nova 5T). Like modern smartphone batteries, it includes built-in protection circuitry (PCM) against overcharge, over-discharge, short-circuit, and overheating.
Official phone specs list the battery as 3750 mAh (typical value); actual capacity can vary slightly between individual units.
