The Lenovo ThinkPad T61 we’ve got for our tests is equipped with a standard battery (5200mAh, 10.8V). It uses 2600mAh power elements, which are the best the market offers today.
The battery doesn’t fit entirely into the battery bay – about half of it protrudes from the back of the notebook. This would be normal for a sub-notebook, but not quite for a 14” model. A 14” notebook usually has enough of space inside the case to accommodate a battery. Slim batteries, which fit entirely into the case, are available for the ThinkPad T61 as well, but their capacity is smaller, and the battery life shortens with them accordingly.
The power adapter is a very nice thing. It is small, much smaller than regular 14” notebooks with discrete graphics come with. The adapter has a special brace for neatly fastening the coil of cable for transportation.

The battery life isn’t impressive in comparison with the opponents, yet it is good by itself. The notebook can last over 4 hours in minimum consumption mode. Two hours and a half when playing a DVD should be quite enough for watching a regular movie.
