Lenovo 5B10W13973 Replacement Battery Review

Lenovo 5B10W13973 replacement battery, the 4-cell 15.44V 57Wh internal battery for the ThinkPad X1 Carbon Gen 9 (2021), also listed by Lenovo for the X1 Carbon Gen 10 and X1 Yoga Gen 6.

Lenovo treats 5B10W13972 through 5B10W13975 and 5B11M90056 through 5B11M90058 as interchangeable service parts for this battery, so any of those numbers on the old pack points to the same replacement.

What to check before you buy

The battery sits under the bottom cover. Turn off the built-in battery in the BIOS before disconnecting it. Confirm your machine type (20XW or 20XX for Gen 9) on the bottom label.
