Replacement battery for ASUS VivoBook 15

The LXHY C21N1818-1 is a new lithium-ion replacement battery rated at 7.6V and 4110mAh (32Wh). It matches the original three-cell pack used in a wide range of ASUS VivoBook 15, X512, R564, S512, A512 and K512 models. Two screwdrivers are included for straightforward installation.

Upgrades a worn original pack

This unit replaces part numbers C21N1818-1, 0B200-03280800 and 2ICP7/54/83 when the factory battery no longer holds a useful charge. The jump is worth it when run-time has dropped noticeably or the laptop shuts down under load despite showing remaining capacity. Rated for up to 500 charge cycles, it restores mobility without changing the laptop.

Suits owners of listed VivoBook models

It fits the specific ASUS series named in the compatibility list and ships with the tools needed for a DIY swap. Buyers whose laptops use a different part number or a higher-capacity pack should look elsewhere, as will users needing a battery with a different voltage or cell count.
