Replacement Battery for VivoBook 15 Series

This 48Wh lithium-ion cell replaces the original B31N1723 pack in Asus VivoBook 15 K570UD, K570ZD, X570UD and X570ZD models. It delivers 11.4V and matches the 31CP7/60/80 part number used across the FX570, R570 and F570 families. Buyers restoring a 15.6" notebook to factory runtime will find it a direct fit.

Capacity and Runtime Expectations

At 48Wh the pack supports typical office workloads and media playback for several hours on a full charge. Heavy GPU tasks or sustained high brightness will drain it faster, so users running demanding creative applications should keep the AC adapter nearby. The 12-month warranty covers premature capacity loss under normal use.

Included Hardware and Support

The black battery ships as a single unit with no extra cables, tools or software. Installation relies on the laptop's existing screws and connectors. The supplier offers email support with a 24-hour response window for compatibility questions or fitting issues before any negative feedback is left.

Questions about this item

Will the 11.4V 48Wh B31N1723 battery fit the original battery bay in my VivoBook 15 K570UD without modification?

Yes, this B31N1723 unit is built to the same form factor as the original 31CP7/60/80 pack, so it seats directly in the existing bay of the K570UD, K570ZD, X570UD and X570ZD models.

How can I verify the 11.4V 48Wh battery is charging correctly after installation?

Power on the laptop and confirm the OS reports a charging state and shows a design capacity near 48Wh; the battery icon should climb steadily while the AC adapter is connected.

Does the package include only the B31N1723 battery or are tools and a replacement AC adapter also supplied?

The box contains the 11.4V 48Wh Li-ion battery itself; no screwdrivers, opening tools or AC adapter are included.
