Who It's For

This replacement battery is aimed at owners of the Lenovo ThinkPad X1 Carbon 5th Gen (2017) and 6th Gen (2018) who need a like-for-like replacement that matches part numbers such as 01AV430, 01AV431, 01AV494 and 01AV429. It suits IT technicians, refurbished laptop sellers and end users comfortable opening the rear case to check the original battery model before purchase.
