Is the T61 6-cell battery the same physical size as the 7-cell battery?

Just found out. They're the same physical size. 7-cell is just slightly heavier.

How much more running time does that extra cell give?

Apparently around 30-40 minutes

Wow. That's a lot for one cell. Didn't expect more than 15-20 minutes extra.

Hoping for a 9-cell.

30-40 minutes here is only a light usage (using words, surfing internet without hard drive access).
If you use hard drive intensive process, it might reduce to 20-25 minutes.

is the 9-cell battery also of the same size. I remember seeing some thinkpad images where the battery protrudes outside. Looks awful

For T61, 6 and 7 cells stick out an inch as well.

9 cell battery for T61 has not been planned yet. Reports say only 4-cell battery does not stick out.
