Steady output during long work sessions

The 11.55V lithium-ion chemistry maintains consistent voltage across the discharge curve, so the notebook runs stable during extended use rather than only in short bursts. Capacity of 42Wh supports typical office and media workloads through a full day without the voltage sag seen in aged cells.

Questions about this item

Which Asus VivoBook models accept the C31N1806 42Wh 11.55V battery as a direct replacement?

The battery replaces part numbers C31N1806, C31PIJ1 and 3ICP5/58/78 and fits Asus VivoBook S13 S330F, S330FA, S330FN, S330UA, X330F, X330FA, X330UA, K330 and R330 series laptops.

Will the 11.55V 42Wh battery work in a VivoBook that originally shipped with a lower-capacity pack?

Yes, the 11.55V voltage matches the original specification, so the higher 42Wh capacity simply provides longer run-time without changing the power profile.

How can I confirm the new C31N1806 battery is recognised and charging correctly after installation?

The operating system should show the 11.55V 42Wh capacity, report a charging state when plugged in, and the battery indicator should progress normally through charge cycles.
