Signs the Battery Needs Replacing

A laptop that shuts off at 30 to 40 percent, drains fast, only runs on the adapter, or has a swollen bottom case needs a new battery.

Why Replace It Early

A weak battery makes the laptop depend on the charger, which strains the charging circuit and risks losing work in a power cut. A swollen pack can also damage the case.

What You Get

You get one new Lenovo ThinkPad T400 laptop battery with a 6 month warranty. Send us your laptop model or the old battery label and we will 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

Avoid leaving the laptop at 100 percent on the charger for days, keep it away from heat, and let it drop to about 20 percent now and then, which slows capacity loss.

Before You Order

These older ThinkPads share several 42T battery codes, so a quick check of the label under your old battery saves a wrong purchase. Bring the old pack to Elephant Road and we will compare it side by side.
