Compatible replacement battery for ThinkPad X1

This lithium-ion battery replaces part numbers L20C4P71, L20D4P71, L20L4P71 and L20M4P71 for the ThinkPad X1 Carbon Gen 9 2021 series. It supplies 56Wh or 57Wh at 15.44V or 15.48V depending on the unit shipped. The pack is new and comes in black.

Voltage variation across interchangeable part

The supplier ships any of the four compatible part numbers, which have slightly different voltage ratings of 15.44V or 15.48V. The laptop's charging circuit manages this variation, so the installed unit will operate correctly. Capacity is rated at 56Wh or 57Wh across the range.

Verify your current battery part number before

Check the label on your existing battery for one of the listed part numbers such as 41CP5/41/108, SB10T83215 or 5B10W13972. Confirm the laptop model is a ThinkPad X1 Carbon Gen 9 2021 variant. This battery is not for other ThinkPad generations or non-Lenovo ultrabooks.

Questions about this item

Which part number should I pick — 41CP5/41/108, L20C4P71, L20D4P71 or L20M4P71?

All four part numbers are cross-compatible; the supplier ships whichever variant is in stock and it will work in your ThinkPad X1 Carbon Gen 9 2021.

What does the 56Wh/57Wh rating mean for daily runtime on my X1 Carbon Gen 9?

The 56Wh or 57Wh capacity matches the original battery, so you can expect the same hours of use per charge as when the laptop was new.

Does the 15.44V/15.48V voltage difference affect compatibility with the ThinkPad X1 Carbon Gen 9?

No — the manufacturer notes that L20C4P71, L20D4P71, L20L4P71 and L20M4P71 are compatible with each other despite the small voltage variation.
