Replacement battery for ThinkPad E14 and E15

This lithium polymer battery delivers 57 Wh at 11.52 V and replaces part numbers L20C3PD4, SB11C73240 and 5B11C73245 among others. It is built for owners of ThinkPad E14 or E15 3rd Gen 2021 and 4th Gen 2022 models who need a direct plug-and-play swap. Buyers with 1st Gen 2019 or 2nd Gen 2020 units cannot use this pack.

Compatibility limited to listed generations

The pack fits only the specific ThinkPad E14 and E15 generations named in the data: 3rd Gen 2021 and 4th Gen 2022 series. Earlier 2019 and 2020 models are explicitly excluded, and no other laptop families are supported. The battery uses the original connector and form factor for those machines, so it will not work in systems requiring a different pin-out or physical layout.

Verify the original battery part number before

Open the back case and confirm the model printed on your existing battery matches one of the listed part numbers such as L20C3PD4, L20M3PD4, L20D3PD4 or L20L3PD4. Cross-reference the part number rather than the laptop model alone, because sub-variants exist within the same series. Read the installation manual carefully before fitting the replacement.
