Replacement battery for Asus ZenBook 13, 14.

This 15.48V lithium-ion pack delivers 67Wh of capacity across four cells. It is built for owners of compatible Asus ultraportables who need a new power source because the original cell has lost runtime or no longer holds a charge.

Direct swap for C41N1904 and C41N1904-1 part numbers

The unit matches the factory voltage and cell count so the laptop recognises it without firmware changes. The jump is worth it when your current battery reports significantly reduced wear level or shuts down under load despite showing remaining percentage.

Questions about this item

What connector and voltage does the 15.48V 67Wh 4-cell pack use to fit the ZenBook 13 UX325EA chassis?

The battery is a direct replacement for the original C41N1904 unit, matching the 15.48V Li-ion specification and the factory connector used in the ZenBook 13 UX325EA series.

Which screw pattern secures the 4-cell 67Wh pack inside a ZenBook Flip 13 UX363EA, and what step is often missed?

Remove the bottom case screws, disconnect the old pack, then connect the new battery before re-assembling; the step often missed is re-seating the connector fully so the firmware recognises the 4347mAh capacity.

When should the 15.48V Li-ion 4-cell unit be replaced in a ZenBook S UX393EA?

Replace the pack when run-time falls well below the original 67Wh rating or the system reports a permanent capacity loss; the 4-cell Li-ion chemistry degrades gradually with charge cycles and age.
