GreenTech L20M3P71 replacement battery

This 52.9 Wh lithium-ion pack is built for ThinkPad X13 Yoga Gen 2 and Gen 3 models as well as the P16 Gen 1 mobile workstation. It restores original runtime for professionals who rely on these ultraportable and performance laptops for daily work.

Three-cell design with multiple safety

The black 11.58 V unit carries CE, FCC and RoHS marks and has been tested for correct voltage, circuit protection, stable current and low self-discharge. Its form factor matches the OEM battery bay so installation requires no tools or modifications.

Direct substitute for nine Lenovo part numbers

It replaces 5B11A13107, 5B11A13108, 5B11A14635, L20C3P71, L20L3P71, L20M3P71, SB11A13105, SB11A13106 and SB11A14634. The upgrade is worthwhile when the original pack no longer holds a full charge or shows swelling, but it does not add capacity beyond the factory 4570 mAh rating.

Questions about this item

Does the 11.58V 3-cell lithium-ion design limit the charge cycle count compared to higher-voltage packs?

The 11.58V three-cell lithium-ion chemistry delivers 52.9Wh and 4570mAh, matching the original specification for the supported ThinkPad models.

Will the L20M3P71 fit the X13 Yoga Gen 3 21AW without modifying the battery bay?

The pack replaces OEM part numbers L20C3P71, L20L3P71, 5B11A13107 and SB11A13106, so it seats directly in the existing bay on all listed X13 Yoga Gen 2, Gen 3 and P16 Gen 1 units.

What is the correct installation sequence for the GreenTech L20M3P71, and which step is most often missed?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector, fit the new pack, reconnect the connector, refit the base and then calibrate with a full charge cycle.
