Lenovo 01AV430 Replacement Battery Review
Lenovo 01AV430 replacement battery, the 3-cell 11.52V 57Wh internal battery for the ThinkPad X1 Carbon 6th Gen (2018) and X1 Carbon 5th Gen (2017).
Lenovo treats 01AV429, 01AV430, 01AV431 and 01AV494 as interchangeable service parts for this battery. One Lenovo entry for 01AV494 quotes 11.58V instead of 11.52V; the capacity and cell count match across all four.
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. Lenovo does not list this part for the X1 Carbon 7th Gen, so confirm your generation from the machine type on the bottom label (20KH or 20KG for 6th Gen).
