Genuine Lenovo 9 cell laptop battery in good condition. FRU P/N: 92P1133. Supports T500, R500, W500, SL300, SL400, SL500, Z60m, Z61m, Z61e and non 14 Wide T60, R60, T61, R61 ThinkPad models (does not support 14.4" wide models). As the Lenovo power manager shows, the battery still holds almost 85% of it's design capacity. This means that there is a lot of life left in this battery.

Always use the OEM (Lenovo) batteries as they are higher quality and last longer. The generic batteries have low prices but their quality is inferior. Don't risk damaging your expensive laptop with a cheap generic battery or run out of power when you need it most and least expect it.

These battery also come with the Panasonic brand cells which last the longest.  If you buy a battery from Lenovo, there is no guarantee on the brand of cell (mostly Sanyo) that you will get. With this battery you are guaranteed that it is Panasonic brand cells.

This battery lists for $179 on the Lenovo web site.

Please note that I can only guarantee what the Lenovo power manager shows as the full charge capacity and I can not guarantee what run time you will get with your laptop as that can vary widely with your usage.
