This is a brand new Genuine 8 Cell Lenovo 40Y7003 ThinkPad battery. This long run battery will run at least 50% longer than the standard capacity battery that ships standard with your laptop. The added run time is achieved with an additional 3 cells inside the cartridge. This longer running battery will extend to the rear of your laptop about 1 inch. Users of this battery pack experience an additional 1-2 hours of run time over the standard battery.
Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness.
If you are using the docking station, this battery will also work with the docking station even though it protrudes to the rear of the laptop. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
Not all computer batteries have the same capacity and run times. The higher capacity battery cells inside this 40Y7003 cartridge have an energy capacity of 5200 mAh. These are the highest quality Li-ion batteries on the market today and superior to batteries rated at 4400 & 4800 mAh. This battery will deliver more run time than cheaper 4 cell versions.

This battery replaces the IBM Lenovo ThinkPad X60, X60s, X61, X61s series laptop batteries. If you have a tablet this battery will not fit. This battery is for X60 and X61 laptops only.
