Previously, when you bought a Lenovo ThinkPad you got a 1 year battery warranty. If you had a 3 year system warranty, your battery only had a 1 year warranty. We all know that batteries are not good for a lifetime and will likely need replacement several times within the lifespan of the laptop itself.

Beginning May 19th, Lenovo launched an extended battery warranty program for ThinkPads. You do have to purchase the battery warranty within 90 days of system purchase, which I believe applies for a regular extended warranty as well, and the term of the battery warranty must match the system warranty. 

For those looking to add this on to your ThinkPad, you can find the part numbers below. I don’t have an accurate price list, but it looks like pricing will start at $139, which is about the cost of a new battery.
