Get up to 7 hours of battery life with an Extended Run Lenovo ThinkPad 64++ battery. This battery is compatible with the ThinkPad X60 and X61 tablet PC models.
This 8 cell long run battery will run at least 50% longer than the standard 4 cell battery. Because of the additional cells, this longer running battery will extend to the rear of your tablet about 1 inch. You'll normally get 3-4 hours of extra battery life over the standard battery. If you're looking for the standard 4 cell version, go to our Lenovo 25 battery for ThinkPads.
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 higher capacity battery cells inside this 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 2200 & 2600 mAh.
