02K6644 - Lenovo/IBM Thinkpad T20 Battery 4400mAh

Keep yourself mobile with a long life Lithium based Notebook Battery. Lithium-Ion and Lithium Polymer batteries typically have longer lives than most other batteries, therefore they do not require replacement as often. Most of our batteries have internal circuit boards that allow the battery to communicate battery performance, temperature and voltage to your Laptop computer. This feature allows your Notebook to more accurately communicate information like "remaining runtime" to you through the battery status lights and/or fuel gauge. Our batteries are manufactured and tested to ensure that they equal or exceed your Notebook's Original Equipment. And, whether you travel around the world or from your office to your home, maintain uninterrupted work cycles by taking a spare battery with you.

Note: Laptop Battery life may vary depending on applications, power management settings and features utilized. Recharge time varies depending on usage. Some batteries may not charge while computer is consuming full power.
