Replacement battery for ZenBook 13 and 14

This 50Wh lithium-ion unit operates at 11.55V and replaces part numbers C31N1841, 0B200-03420200 and 3ICP5/70/81. It is built for Asus ZenBook Edition 13 UX334 series and ZenBook 14 UX434, UX463 series laptops. The black pack restores original runtime for daily work and travel.

Verify the exact model before ordering

Match the part number on your existing battery to C31N1841 or 3ICP5/70/81 and confirm the laptop appears in the supported list such as UX334FL, UX434FL or UX463FL. Different sub-models within the same series can use different packs, so a visual and part-number check avoids a mismatch.

Steady output during long sessions

The lithium-ion chemistry maintains a stable 11.55V through extended workloads rather than sagging after a short burst. Consistent voltage lets the ultrabook sustain its performance profile during video editing, compilation or long meetings without unexpected throttling or early shutdown.

Questions about this item

Does the C31N1841 50Wh battery arrive ready to install or do I need extra screws or tools?

The battery is a direct replacement for part numbers C31N1841, 0B200-03420200 and 3ICP5/70/81; it fits the listed ZenBook models without additional hardware.

My ZenBook 14 UX434FL shows part number 3ICP5/70/81 — is the 50Wh 11.55V version the correct capacity?

Yes, the 50Wh 11.55V lithium-ion cell matches the original 3ICP5/70/81 specification for UX434FL and related UX434 models.

What runtime can I expect from the 50Wh rating once the battery is inside a UX334FL?

The 50Wh capacity restores the factory-rated energy of the original C31N1841 pack, delivering the same watt-hour reserve Asus designed for the ZenBook 13 UX334 series.
