Signs the Battery Needs Replacing

Look for a charge that drains within an hour, a ThinkPad that shuts down when you unplug it, or a battery that stalls at a low level.

Why Replace It Early

A worn battery in a slim ultrabook runs warmer and keeps you near a socket. Replacing it early protects your work and keeps the ThinkPad portable.

What You Get

You get one new 01AV409 battery pack. Our team can check the fit for you before you buy, so you avoid a wrong order and a second trip to the shop.

Care Tips for Longer Life

Keep the laptop away from heat, avoid leaving it at full charge on the adapter for weeks, and run a full cycle once a month, which slows capacity loss.

Before You Order

Check that your laptop is an X1 Carbon 4th Gen or an X1 Yoga Gen 1 or 2, and read the part number on the old battery. If you are unsure, send us the model name and we will confirm the fit.
