Check Your ThinkPad Model and Part Number

Verify that your laptop appears in the supported list: ThinkPad X200 (2024, 7454, 7455, 7457, 7458, 7459, 7589-xxx), X200s (7466, 7469, 7470-xxx), X201, X201i or X201s. Confirm the original battery part number is 43R9255, 42T4540 or 42T4542. Ensure the battery bay accepts a 9-cell proprietary pack of the stated dimensions. No other ThinkPad series or battery sizes are supported by this unit.

Suits Owners of Listed X-Series Models Needing

This battery suits users who want a new lithium-ion replacement for the compatible ThinkPad X200 or X201 family laptops. It is not for owners of ThinkPad models outside the listed part numbers, nor for machines requiring a different cell count or chemistry.

Questions about this item

What comes in the box with the Axiom 43R9255-AX battery and what must I buy separately?

The box contains the 9-cell lithium-ion battery only; no tools, screws, or AC adapter are included, so reuse your existing charger and the laptop's original mounting hardware.

Which capacity version of the 43R9255-AX should I choose for a ThinkPad X201?

This model is a single 9-cell configuration rated at 100% OEM compatible for the X200, X200s, X201, X201i and X201s series; there are no alternative capacities to select.

What does the 9-cell design mean for daily runtime on an X200?

Nine cells provide higher capacity than the standard 6-cell pack, extending unplugged work time proportionally while adding approximately 1.12 lb and a 0.8 inch rear profile.
