Replacement for ZenBook Duo 14

This 70Wh lithium-ion battery replaces part number C41N2004 in Asus ZenBook Duo 14 models including UX482, UX482EA and UX482EG series. It operates at 15.4V and matches the original black finish. The unit is supplied new with a six-month warranty.

Thermals and power in daily use

Lithium-ion chemistry delivers steady output at 15.4V across the 70Wh capacity without active cooling. Normal operation produces no audible noise and the pack fits the existing chassis bay, so thermal load on the laptop remains unchanged from the factory cell.

When the swap makes sense

The upgrade is worth it when the original pack no longer holds a useful charge or shows rapid capacity loss. It restores factory runtime for the listed UX482 variants but does not add capacity beyond the original 70Wh specification. Buyers needing extended runtime beyond the stock design or a different voltage should look elsewhere.

Questions about this item

How do I install the C41N2004 battery in my ZenBook Duo 14 UX482 and which step do people often miss?

Remove the bottom case screws, disconnect the old battery connector before lifting it out, then connect the new 15.4V 70Wh pack and secure it; the step most people miss is disconnecting the connector first to avoid a short.

What maintenance or replacement will this 70Wh lithium-ion battery need later?

Expect gradual capacity loss over hundreds of charge cycles; when run time drops below your needs, replace it with another 15.4V 70Wh unit matching part numbers C41N2004, 0B200-03790000 or 41CP6/60/72.

What limit appears first during sustained heavy use of this 15.4V 70Wh pack?

The 70Wh capacity ceiling is reached first; once the stored energy is depleted the system will throttle or shut down until the battery is recharged.
