42 Wh replacement for VivoBook 14

This lithium-ion battery replaces the original B31N1912 and C31N1912 packs in Asus VivoBook 14 E410, L410, F414 and E510 series notebooks. It delivers 11.55 V and 42 Wh of capacity for owners whose factory cell no longer holds a useful charge. The part is new and rated for up to 500 recharge cycles over its service life.

3550 mAh capacity and daily headroom

At 3550 mAh the pack supplies enough energy for typical office work, web browsing and video playback on the supported 14-inch models. Runtime will fall short for users who run sustained heavy loads such as rendering or gaming, and the cell cannot be expanded beyond its fixed 42 Wh rating.

Included tools and instructions

The box contains one B31N1912 battery, a matched set of installation tools and a printed instruction sheet. These items let a competent owner swap the old pack without sourcing separate screwdrivers or pry tools, reducing the risk of case damage during the repair.
