Direct replacement for ZenBook UX330 series

This 57Wh lithium-ion battery replaces part numbers C31N1602, 0B200-02090000 and 3ICP4/91/91 across the ZenBook UX330 family. It fits models including the UX330UA, UX330UAK, UX330U and U3000U variants. Owners of these ultraportables can restore original runtime without adapter modifications.

Thermals noise and power draw in normal use

The 11.55V Li-ion cell operates within the laptop’s existing thermal envelope and requires no additional cooling. Power delivery matches the factory specification so the system manages charge cycles and fan behaviour exactly as before. No audible noise is introduced by the battery itself.

When the jump is worth it

Replace the original pack when runtime has dropped below usable levels or the system reports a capacity warning. The swap is worthwhile for users who need full mobility again but not for those whose machine has a charging-circuit fault or a swollen-cell safety issue.

Questions about this item

How do I install the C31N1602 battery in my ZenBook UX330UA and which step is often missed?

Remove the bottom case screws, disconnect the old pack from the motherboard connector, fit the new 11.55V unit, reconnect the cable firmly, then reassemble; the step often missed is reseating the connector fully so the 57Wh cell is recognised.

What replacement will the C31N1602 battery need after extended use?

The lithium‑ion pack itself is the only replaceable part; after several hundred cycles the 57Wh capacity drops below useful runtime and the whole battery must be swapped for a new C31N1602 unit.

What limit appears first when the C31N1602 battery runs under sustained load?

The 11.55V lithium‑ion cells hit thermal and voltage sag limits before the 57Wh rating is fully depleted, so runtime shortens noticeably during continuous high‑drain use.
