Direct replacement for ZenBook UX430 series

This 50Wh lithium-ion battery matches the original C31N1620 part for Asus ZenBook UX430 models including UX430UA, UX430UN, UX430UQ and the PU404 Pro variants. It operates at 11.55V and fits the Type B chassis used across the listed ultrabooks. The black unit ships new with a 12-month warranty.

50Wh capacity for typical ultrabook workloads

At 50Wh the pack delivers a full day of light office use or several hours of video playback on the UX430 platform. Heavier sustained loads such as compiling code or discrete GPU tasks will draw the reserve down faster, so users running those workflows should keep the charger nearby.

Proprietary Type B connector limits interchange

The battery uses the Asus-specific Type B interface, so it only fits the exact model families named in the compatibility list. It cannot be swapped with batteries from other ZenBook generations or third-party laptops that use different pinouts or form factors.

Questions about this item

Will the 11.55V 50Wh battery work in my ZenBook UX430UA that currently uses the original C31N1620?

Yes, the 11.55V 50Wh cell matches the original C31N1620 specifications and is listed as compatible with the UX430UA model.

How can I confirm the new 50Wh battery is charging correctly after installation?

The operating system battery indicator should show charging progress and report a design capacity close to 50Wh once the first full cycle completes.

Does the package include any tools or screws for fitting the battery into a UX430UN?

The box contains only the 1x battery; any screwdrivers or replacement screws required for the UX430UN must be sourced separately.
