Direct Replacement Battery

This 62Wh lithium-polymer pack replaces part number C21N1347 and fits Asus ZenBook Pro Duo UX581 models including UX581GV and UX581LV. It restores original runtime for professionals who rely on the dual-screen workflow of this specific ultraportable.

Steady 15.4V Output

The cell chemistry delivers a stable 15.4V at 4038mAh without the voltage sag seen in aged packs. Normal office loads run cool and silent because the battery management board regulates current without active cooling.

Fits Existing Chassis

The black housing matches the original footprint so the laptop lid closes flush and the trackpad click remains unchanged. No adapter cables or BIOS updates are required; the pack simply slots into the compartment vacated by the depleted unit.

Questions about this item

How do I install the C42N1846-1 battery in my ZenBook Pro Duo UX581, and what step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery cable before lifting the pack, then connect the new battery and reassemble; the step often missed is disconnecting the cable first.

What maintenance or replacement will the 62Wh Li-polymer pack need later?

The battery is sealed and requires no user maintenance; replacement is needed when runtime no longer meets your needs after many charge cycles.

What limit appears first on the 15.4V 4038mAh battery during sustained heavy use?

Under continuous high load the pack will reach its thermal and voltage limits, causing the system to throttle performance before the charge is fully depleted.
