ASUS C31N1811 Replacement Battery Review
ASUS C31N1811 replacement battery, the OEM 11.55V 50Wh three-cell pack for the ZenBook 14 UX433 family and the Deluxe 13/14 variants.
Sold directly through ASUS's own accessories storefront under the OEM part number, which is the strongest sourcing tier available in this category.
What to check before you buy
UX433 carries several suffix variants (FA, FN, FL) across different silicon and GPU options, but they share this same battery part. Confirm the full model suffix printed on the base of the laptop to rule out a different ZenBook generation.
