63 Wh replacement battery for select Asus ZenBook

This KingSener C31N1914 battery delivers 63 Wh at 11.61 V using Li-Polymer cells. It is built to match the original dimensions of the Asus ZenBook 13 UX425UG and ZenBook 14 UX435EAL, UM425QA and UM425UAZ series. The pack is supplied new and ready to install.

Who this suits and who should look elsewhere

It suits owners of the listed ZenBook 13 and 14 models who need a direct replacement for a worn or failed C31N1914 pack. It is not for users whose laptop requires a different voltage, a different capacity, or a different physical layout. It is also not for buyers who want an internal battery for a non-Asus chassis.

The specification that decides fit

The decisive figure is the 11.61 V / 63 Wh rating combined with the C31N1914 part number; only laptops designed for that exact voltage, capacity and form factor will accept this battery.
