Verify your current part number before ordering

Check the label on your existing battery for L17C4P72, L17M4P72, L18M4P71, 01AY968, 01AY969 or 01YU911 to confirm an exact match. Ensure your laptop model appears in the supported series list, as other ThinkPad lines use different connectors and voltage ratings.

Single battery unit included in the package

The box contains one replacement battery only; no tools, screws or installation guides are provided. The 12-month warranty covers the cell itself, so retain proof of purchase in case a claim is needed.
