Verify Your Part Number

Before ordering confirm the original battery label shows one of the listed OEM part numbers. Check that your laptop model appears in the supported list above. Ensure the voltage rating on your current pack reads 11.1V. This unit will not fit ThinkPad models outside the stated range or batteries with different voltage or connector layouts.

Upgrade From Worn Original Cells

This battery replaces a factory pack that no longer holds a useful charge. The jump is worth it when run-time has dropped below your mobile workflow needs and the laptop otherwise meets performance requirements. It restores original capacity without changing the chassis or power adapter. Buyers who need higher capacity than 2162mAh or a different form factor should look elsewhere.

Questions about this item

Does the PowerWarehouse 45N1108 battery come with any installation tools or a separate power bank?

The package contains the 3-cell 11.1V 2162mAh battery only. The free power bank mentioned by the manufacturer is a promotional item shipped separately; no screwdrivers or mounting brackets are included.

My ThinkPad is an X250 — is the 45N1108 the correct replacement or should I look for a different capacity?

The 45N1108 fits the X250 as well as the X240, X260, X270, T440, T440S, T450, T450S, T460, A275 and X230S models. All listed systems use the same 11.1V 2162mAh 3-cell specification, so no alternative capacity is required.

What does the 2162mAh rating actually deliver in daily use on a T450?

The 2162mAh capacity at 11.1V provides roughly 24Wh. On a typical T450 workload you can expect several hours of mixed browsing and document editing before recharge, though exact runtime varies with screen brightness, CPU load and battery age.
