Replacement battery for ZenBook Duo 14 UX482

This 15.4V 70Wh lithium-ion unit fits the ZenBook Duo 14 UX482 series including UX482EA, UX482EG and listed sub-models. It replaces part numbers C41N2004 and 0B200-03790000. The black pack is sold new and carries a 12-month warranty.

Swaps the original C41N2004 pack when runtime drops

If the factory cell no longer holds a full day of work, this direct-fit replacement restores the original 70Wh capacity. The change is worth it when the laptop shuts down early or throttles on battery power. It is not for users who need a higher-capacity design than the stock 70Wh layout.

Delivers steady 15.4V output through long sessions

Lithium-ion chemistry maintains voltage under continuous load rather than sagging after a short burst. The pack supports sustained productivity workloads on the ZenBook Duo 14 without sudden shutdowns. It is not for scenarios that demand hot-swap capability or an external charge indicator.

Questions about this item

Will the C41N2004 battery fit inside the Asus ZenBook Duo 14 UX482 chassis without modification?

Yes, the battery is built to the original 15.4 V 70 Wh form factor for the ZenBook Duo 14 UX482 series and matches the 0B200-03790000 part number.

What is the correct installation sequence for the C41N2004 battery in a ZenBook Duo 14 UX482, and which step is most often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector, fit the new C41N2004 unit, reconnect its cable, then reassemble; the step most often missed is disconnecting the internal battery cable before removing the old pack.

How many full charge cycles can the 70 Wh lithium-ion cell in the C41N2004 deliver before capacity drops noticeably?

The 70 Wh lithium-ion cell is rated for typical laptop-battery cycle life; expect gradual capacity reduction after several hundred full charge cycles under normal use.
