Replacement battery for ThinkPad X13 Gen 2 and Gen 3

This GreenTech lithium-ion pack is built to replace the original Lenovo battery in ThinkPad X13 Gen 2 and Gen 3 ultraportables. It matches the OEM voltage of 15.36 V and delivers 54.7 Wh from four cells. The unit is brand new and carries CE, FCC and RoHS safety certifications.

54.7 Wh capacity for typical mobile workloads

At 3564 mAh the pack supplies enough energy for a full day of office applications, web browsing and video playback on the X13's low-power platform. Heavy multi-tasking, sustained CPU loads or high screen brightness will drain the charge faster, so users who regularly push the system to its limits should keep a charger nearby.

Slim black housing with direct-fit connectors

The battery measures 11 by 4 by 0.25 inches and weighs 0.75 lb, matching the footprint of the factory unit so it seats flush in the chassis without adapters. Internal circuitry provides over-voltage, over-current and short-circuit protection, while low self-discharge keeps the pack ready after weeks in storage.

Questions about this item

Will the 15.36V 54.7Wh GreenTech battery work with the original charger that came with my ThinkPad X13 Gen 2?

Yes, the replacement matches the 15.36V voltage and 54.7Wh capacity of the OEM packs listed, so your existing Lenovo charger will charge it normally.

How can I confirm the 4-cell lithium-ion pack is recognised correctly after I install it?

The ThinkPad BIOS and Lenovo Vantage will show the battery at 15.36V, 3564mAh and 54.7Wh with a GreenTech part number such as L20M4P73 or SB10W51919.

Does the box include any installation tools or only the 11 x 4 x 0.25" battery itself?

Only the 0.75 lb battery is supplied; no screwdrivers, opening picks or adhesive strips are included.
