50Wh 3-cell Li-ion replacement battery

This 50Wh lithium-ion battery replaces the original C31N1905 pack in compatible ASUS VivoBook laptops. It uses three A-grade cells at 11.55V to restore factory runtime for daily work and study sessions. The black housing matches the original appearance and fits the designated battery bay without modification. Condition is new and ready for immediate installation.

Fits listed ASUS VivoBook K, S and X series models

Owners of the specific ASUS VivoBook K1703Z, S1505ZA, X1505ZA and X1704VA models shown in the compatibility list can use this pack as a direct swap. Builders repairing other brands, different ASUS series or units requiring a different voltage or cell count should look elsewhere. Buyers who need a higher capacity than 50Wh or a different form factor must choose another part.

11.55V 50Wh three-cell specification

The single specification that determines fit is the 11.55V 50Wh three-cell lithium-ion design. Only laptops engineered for this exact voltage and capacity will recognise the pack and charge it correctly. Verify the original battery label reads C31N1905 or 3ICP5/70/82 before ordering.
