Replacement battery for ThinkPad X1 Carbon 3rd Gen

This 15.2 V lithium-ion pack replaces Lenovo part numbers 00HW002, 00HW003, SB10F46440 and SB10F46441. It fits the ThinkPad X1 Carbon 3rd Gen models 20BS and 20BT. The unit is brand new and has passed voltage, circuit-protection and self-discharge tests. CE, FCC and RoHS certifications confirm compliance with safety standards.

Voltage and capacity match the original

The cell chemistry delivers 15.2 V and 3290 mAh for a 50 Wh rating across four cells. These figures must match the original battery exactly for the laptop to recognise the pack and report charge levels correctly. A different voltage or capacity will cause detection errors or incorrect runtime estimates.

Steady output during extended sessions

The tested circuit protection maintains stable current under continuous load rather than only in short bursts. Low self-discharge keeps the pack ready after periods of storage. The design targets consistent voltage delivery throughout the discharge cycle for predictable runtime.

Not for other ThinkPad models

Buyers with a different ThinkPad series or generation cannot use this pack because the connector and firmware handshake are specific to the 3rd Gen X1 Carbon. Users who need more than 50 Wh of capacity will not find that option in this form factor.

Questions about this item

How long will the 50 Whr rating actually run my ThinkPad X1 Carbon 3rd Gen?

The 50 Whr capacity matches the original specification, so typical mixed workloads should deliver similar runtime to the factory battery when new.

Does the 15.2 V output work with the laptop's charging circuit without modification?

Yes, 15.2 V is the exact voltage the X1 Carbon 3rd Gen expects, and the pack includes the matching connector and protection circuitry.

Will the four-cell pack fit the internal battery bay without case modifications?

The battery is built to the same 4-cell form factor as OEM part numbers 00HW002 and 00HW003, so it seats directly in the existing bay.
