Replacement Battery for ZenBook Duo

The KingSener C41N1901 is a lithium-ion battery rated at 15.4V and 70Wh capacity. It serves as a direct replacement for the original unit in compatible Asus ZenBook Duo models. The cell assembly is manufactured in China and supplied in black finish. This product is sold new and intended for users restoring battery life to supported ultraportable laptops.

Suitable for owners of listed ZenBook Duo models

This battery fits the UX481F, UX481FA, UX481FL, UX4000F and UX4000FL series as specified by the supplier. Buyers whose laptops use a different part number or voltage should look elsewhere. It is not intended for models outside the stated compatibility list. Professional installation is recommended if the user is unfamiliar with internal laptop components.

70Wh capacity for typical mobile workloads

The 4550mAh cell provides enough energy for everyday productivity, web browsing and media playback on supported hardware. Runtime will vary with screen brightness, background tasks and power-profile settings. Heavy multi-threaded workloads or sustained GPU activity will deplete the charge more quickly. The battery weighs 270g and matches the physical envelope of the original pack.
