Compatible replacement for ThinkPad L14 Gen 5

This GreenTechLLC battery replaces the original Lenovo power pack in ThinkPad L14 Gen 5 and L16 Gen 1 laptops. It delivers 11.31V and 57Wh from a three-cell lithium-ion design. The unit is brand new and carries CE, FCC and RoHS safety certifications.

Slim internal pack with standard connector

The black casing measures 11.5 by 3.25 by 0.25 inches and weighs 0.7 lb, matching the factory form factor for a direct fit. No adapters or cable modifications are required; the battery seats into the existing bay and locks with the original latch mechanism.

Restores runtime lost to an aged original cell

Owners whose factory battery no longer holds a useful charge can swap in this 5040 mAh unit to regain full mobile operation. It is not suited for users who need a higher-capacity pack than the OEM 57 Wh specification or who require a hot-swappable secondary battery.
