Replacement Battery for Asus ZenBook

The Beisite C41N1904 is a 67Wh lithium-ion battery built to replace the original pack in compatible Asus ZenBook 13, 14 and Flip models. It targets owners of machines such as the BX325JA, UM325SA, UM325UA, UX325EA, UX325JA, UM425IA, UX425EA, UX425JA, UX363EA, UX371EA, UX391UA and UX393EA who need a fresh power source. The unit ships new and carries a 12 month warranty.

Fit and Connectors

The black pack uses the same 15.48V layout and the 4ICP5/49/121 form factor as the factory part numbers C41N1904, C41N1904-1 and the 0B200-03660xxx series. Direct connector alignment means the battery drops into the chassis without cable adapters or case modification. Screw holes line up with the existing mounts so installation follows the standard service procedure for the listed ZenBook families.

Thermals and Power

Lithium-ion chemistry delivers the rated 67Wh at the specified 15.48V with no active cooling required. The pack runs passively inside the notebook, adding no audible noise and drawing no extra power beyond the system's normal charge cycle. Operating temperatures stay within the laptop's designed thermal envelope during typical workloads.

Questions about this item

What voltage does the 15.48V lithium-ion battery deliver to the Asus ZenBook 13 UX325EA?

The battery supplies 15.48 volts and 67 watt-hours, matching the original C41N1904 specification for the UX325EA and other listed ZenBook models.

Will the C41N1904 battery fit inside the ZenBook 14 UX425JA chassis without modification?

Yes, the replacement part numbers C41N1904, C41N1904-1 and 4ICP5/49/121 are listed as direct fits for the UX425JA and the wider ZenBook 13, 14, Flip 13, Flip S and S series.

Which screw steps are commonly missed when installing the C41N1904 battery in a ZenBook 13 UX393EA?

After removing the bottom case screws, disconnect the old battery connector before lifting the pack; forgetting to unplug the connector first is the step most installers skip and can damage the motherboard header.
