Replacement Battery for ThinkPad X1

This lithium-polymer replacement battery fits a wide range of ThinkPad X1 models including the 20FB and 20FC series. It is built for owners who need a direct swap for a worn or failed original pack. The cell chemistry matches the factory specification so the laptop recognises it immediately.

3300 mAh capacity with 50.16 Wh energy

At 3300 mAh and 50.16 Wh the pack delivers the same rated capacity as the original unit, supporting typical office workloads and media playback for a full workday. Runtime will decrease under sustained heavy loads such as video rendering or virtual machines, where the fixed capacity reaches its limit sooner than higher-watt-hour alternatives.

15.2 V nominal voltage

The battery operates at 15.2 V, a value that must match the laptop’s power rail exactly. If the original battery label shows a different voltage the pack will not charge or may trigger a safety shutdown, so verify the voltage before ordering.

Questions about this item

Will the 15.2 V 3300 mAh battery fit my ThinkPad X1 20FB002RAU without forcing the case?

Yes — it matches the original 305.50 × 109.70 × 5.00 mm footprint and 497 g weight, so the laptop chassis closes normally.

How can I confirm the new pack is charging correctly after installation?

The battery should report 15.2 V and reach 50.16 Wh when full; the OS battery icon will show a steady charge curve and no error codes.

Does the package include the tiny Phillips screws needed to secure the battery, or must I reuse the old ones?

Only the lithium-polymer cell is supplied; you reuse the original screws and any connector brackets from the old pack.
