ASUS C31N2021 Replacement Battery Review

ASUS C31N2021 is an OEM replacement laptop battery rated 11.61 V and 63 Wh, listed for the ASUS Zenbook 14X UX5401 with a 2.8K OLED display.

A 63 Wh, 11.61 V replacement pack from an OEM source. The capacity figure is a seller claim rather than an OEM label reading, which is worth knowing when comparing runtime. The listed laptop is the ASUS Zenbook 14X UX5401 (Core i7-1195G7, 16GB, 2.8K OLED). The listing does not confirm that other UX5401 configurations use the same code, so compare the code C31N2021 on your pack before buying. The expected firmware state is full function, and it ships under classification UN3481.

What to check before you buy

Confirm the OLED panel option on your UX5401 before ordering, since panel variants of this chassis can carry different battery capacities.
