Capacity and Voltage Limits

The cell provides 57 watt-hours and 4950 milliampere-hours at 11.52 volts. Runtime will vary with system load, screen brightness and power-management settings. This unit does not increase the original design capacity of the laptop. It restores the factory runtime envelope.

Match the Original Part Number Before Buying

The single specification that decides fit is the exact part number printed on your existing battery. Open the rear case and verify the code matches one of the listed replacements. Buyers who need a different voltage, capacity or form factor cannot use this pack.

Questions about this item

Which battery part number matches my ThinkPad X1 Carbon 5th Gen or 6th Gen?

This unit replaces Lenovo part numbers 01AV430, 01AV431, 01AV429, 01AV494 and SB10K97586, SB10K97587, SB10K97588 used in those models.

What does the 57Wh rating mean for daily runtime?

The 57 watt-hour capacity stores the same energy as the original factory pack, so typical mixed workloads should return to near-new battery life.

Does the 11.52V output require any special connector or firmware?

No — the pack is a plug-and-play lithium-ion design that connects to the standard internal battery header on the X1 Carbon 5th and 6th Gen boards.
