Replacement battery for ThinkBook 16

This lithium-ion battery replaces Lenovo part numbers L22B4PE1 through L22M4PE1 and fits ThinkBook 16 Gen 6 and Gen 7 models. It is a direct swap for the original pack and restores mobile power to compatible laptops. The pack ships new and ready to install.

Voltage and capacity match

The cell operates at 15.36V and stores 71Wh of energy, which is the single specification that decides fitment. ThinkBook 16 Gen 6 uses two different battery capacities that are not interchangeable, so confirming this voltage and capacity against the original unit is essential before purchase.

Sustained discharge stability

Lithium-ion chemistry delivers steady voltage throughout the discharge curve rather than a sharp drop near empty. This behaviour supports consistent runtime during long work sessions and reduces unexpected shutdowns under continuous load.
