Genuine 57Wh 4-Cell Replacement

This genuine Lenovo 57Wh 4-cell battery is built for the ThinkPad X1 Carbon 9th Gen. It restores original runtime for mobile professionals who rely on consistent daily use. The OEM part matches the factory specification without modification. MPN 5B10W13973 confirms exact fitment for the target model.

AC/Standard Interface Limits

The AC/Standard interface means the pack communicates through the laptop’s built-in charging controller. No external circuitry or adapter is required for installation. Capacity cannot exceed the chassis allowance, so runtime stays within the 57Wh design envelope. Users needing longer unplugged time must accept this fixed ceiling.

57Wh Capacity Decides Fit

The single figure that determines suitability is the 57Wh rating. If the original battery carried the same value, this part will slot in and report correct charge levels. A different watt-hour rating would signal a mismatch for this ultrabook chassis. Buyers who need a higher or lower capacity must look elsewhere.
