Replacement battery for ZenBook Edition 30

This 50Wh lithium-polymer cell replaces part number C31N1841 in Asus ZenBook Edition 30 UX334FL, UX434FL and UX463FL ultraportables. It delivers 11.55V and 4335mAh in a black housing. The unit is brand new and matches the original form factor.

Questions about this item

How long will the 50Wh capacity last under continuous load?

The 50Wh rating and 4335mAh capacity define the total energy available; actual runtime depends on the specific laptop model and workload intensity.

Does the 11.55V Li-polymer battery generate noticeable heat during all-day use?

Li-polymer chemistry at 11.55V typically runs cool under normal operation; sustained heavy loads will warm the pack but it has no active cooling to produce noise.

Which exact Asus ZenBook model numbers are confirmed compatible with this C31N1841 replacement?

Verified models include UX334FL, UX434FL, UX434DA, UX434FA, UX463FL, UM433DA, U3600F and U4600F.
