Compatible replacement battery

This lithium-ion battery replaces several Lenovo part numbers for ThinkPad X1 Carbon 12th Gen and X1 2 in 1 Gen 9 models. It ships as one of four interchangeable variants depending on stock. The unit is brand new and ready to install.

Voltage and capacity limits

The cell delivers 11.7 volts and 56.1 watt-hours, matching the original specification for the listed laptops. Buyers who need a higher capacity or a different voltage should look elsewhere because this pack is built to the factory rating only.

Deciding part number match
