ThinkPad X60 X61 ThinkPad Battery 64++ (8 Cell - X60 X61 Tablet PC)

Get up to 7 hours of battery life with an Extended Run Lenovo ThinkPad 64++ battery.

This long run battery will run at least 50% longer than the standard capacity battery that ships standard with your tablet. 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 tablet about 1 inch. Users of this battery pack experience an additional 3-4 hours of run time over the standard battery.

Estimated run time with this battery is 5-7 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness. The superior South Korean cells inside the battery cartridge will provide longer run times between charges as well as a longer service life than cheaper batteries.

Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your tablet any time without diminishing your battery capacity. This brand name tablet battery is typically superior to the original battery and is 100% compatible with your Lenovo ThinkPad tablet computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
