This review is from: ThinkPad 08K8190 Ultrabay Slim Li-Polymer Battery


Slim, fits where the DVD normally stays without added bulk although a bit heavier then the DVD drive. Adds about an hour on an optimized T60P, the hour that you always need.


This is only a 3 cell battery providing very little extra time (about an hour WHEN NEW, ONLY WHEN NEW). Comparing to the 9 cell extended battery that I already have on the T60P, this provides a third of that. Problem is that this battery quickly looses its maximum capacity and within less than a year and about 100 cycle charges you get less than 60% the capacity. The battery now is labeled as in "fair condition". By comparison the main extended 9-cell battery with more charge cycles lost only about 10% of capacity in about 18 months. I'd like to add here that the main extended battery has cells made by Panasonic while this 3-cell battery has cells made by SONY.

Other Thoughts:

If you are the kind of person who does everything on the "last drop of juice" this might save your behind, otherwise this battery quickly turns into a paper weight.
