Check your part number before ordering

Verify that your original battery carries one of the listed part numbers such as L19C3P71, L19M3P72, L19M3P73 or 3ICP5/74/78. The supplier notes these three model codes are interchangeable despite voltage differences and will ship whichever is available. This unit is not suitable for ThinkPad models outside the X1 Nano Gen 1 line or for laptops requiring a different form factor or connector layout.

Behaviour under sustained load

The 48.2Wh lithium-ion cell delivers a steady 11.58V output during extended use, supporting consistent run time for typical productivity workloads. Capacity remains stable across repeated charge cycles when the battery is kept within normal operating temperatures. It is not designed for high-drain gaming or workstation loads that exceed the ultraportable power envelope of the X1 Nano Gen 1 platform.
