Compatible ThinkPad Models

This Lenovo 45N1025 battery fits the ThinkPad X220, X220i and X230 notebooks. It is a direct replacement for the original proprietary pack supplied with those systems. Buyers who need a battery for other ThinkPad series or for non-Lenovo laptops cannot use this unit.

Rechargeable Lithium-Ion Chemistry

The pack uses lithium-ion cells and is fully rechargeable through the notebook’s standard charging circuit. No external charger or special maintenance routine is required. Users who require a non-rechargeable primary cell or a different chemistry will not be served by this product.

Physical Dimensions and Weight

The battery measures 8.2 inches wide, 2.2 inches deep and 0.9 inches high, weighing approximately 12.17 ounces. Its proprietary shape matches the X220 and X230 battery bay exactly. Builders looking for a standard rectangular form factor or a lighter pack for a different chassis will find this item unsuitable.

Questions about this item

How do I install the 45N1025 battery in a ThinkPad X220, and what step is often missed?

Power off the notebook, slide the release latch, remove the old pack, insert the 45N1025 until it clicks, then charge fully before first use; the step often missed is the initial full charge.

What maintenance or replacement will the 45N1025 lithium-ion battery need later?

The rechargeable lithium-ion pack will gradually lose capacity over charge cycles; plan to replace it when runtime drops below your needs, as no user-serviceable cells are inside.

What limit appears first on the 45N1025 during sustained use?

The 12.17 oz lithium-ion pack will hit thermal limits before its capacity rating under sustained high loads, causing the notebook to throttle performance to protect the cells.
