Direct replacement for ZenBook Duo series

This 15.4V lithium-ion battery replaces the original C41N1901 unit in Asus ZenBook Duo UX481 models including UX481FA, UX481FL and their regional variants. It delivers 70Wh capacity and 4550mAh charge in a black housing that matches the factory part. The cell is new and rated for 12 months of warranty coverage.

Upgrade from a degraded or failed original

Owners of a UX481FL-BM020T, UX481FA-BM018R or any listed SKU whose runtime has fallen below useful levels will regain full mobile operation with this swap. The jump is worth it when the old pack no longer holds enough charge for a typical work session away from mains power.

Verify your exact model code before ordering

Check the label on the bottom of the laptop or in the BIOS for a part number such as C41N1901, 4ICP6/60/72, 0B200-03520000 or 0B200-03520100. Confirm the machine model appears in the supported list, which covers UX481FL-BM002T through UX481FL-BM071T and ZenBook Duo UX481FL-BM044T variants.
