Direct replacement for Asus Zenbook UX430 series

This 50Wh lithium-polymer battery operates at 11.55V and matches the C31N1620 part number. It is built for owners of UX430, UX430U, UX430UA, UX430UAR, UX430UN, UX430UNR, UX430UQ, U4100, U4100U, U4100UN, U4100UQ, UX3400, UX3400U, UX3400UA, UX3400UN, UX3400UQ and BX430UA notebooks who need a factory-specification power source.

Simple internal swap with no soldering required

The pack sits in the standard battery bay and connects through the existing header. Most installations finish in under fifteen minutes with a small Phillips driver. The only common issue is the firmware not recognising the new cell on first boot; a full charge cycle followed by a BIOS reset usually resolves it.

Delivers 50Wh at 11.55V for typical ultrabook

Expect several hours of office tasks, web browsing or video playback on a full charge. Heavy sustained loads such as rendering or gaming will drain the pack faster and may trigger thermal throttling before the rated capacity is reached. It is not suited for users who require all-day runtime without access to a charger.

Questions about this item

How do I verify the NShi C31N1620 is charging correctly after installation?

After fitting the 11.55V 50Wh lithium polymer pack, the operating system should show the battery charging and report a design capacity near 50Wh once calibration completes.

What is included with the NShi C31N1620 and what must I source separately?

The box contains the replacement battery only; no tools, screws or adhesive strips are supplied, so have a suitable screwdriver set ready for the UX430 or UX3400 chassis.

Which part number should I match to ensure the NShi C31N1620 fits my ZenBook?

Confirm your original battery carries one of the listed codes such as 0B200-02860000, 0B200-02370000, 0B200-02370100 or 0B200-02370200 before ordering.
