Default Opened laptop battery to replace lithium ion cells (Lenovo X61tablet PC) -- Where do I get replacement battery cells?

Have you ever opened up your laptop battery to replace the lithium ion
cells inside (if so, I could use the help as I'm stuck).

Here are the pictures of the operation on a Lenovo X61 tablet PC 8-cell
4500 amp-hour battery kidney-transplant operation.

The outside of the IBM Lenovo X61 tablet PC battery pack has the part
numbers:
- FRU 42T4507
- ASM 42T5209

And the batteries themselves, seem to have numbers on them of:
- cylinders BCM 3A6 72653
- rectangles C 3 171353

Any idea where to obtain these lithium ion replacement batteries?

Hi. I realize that this is an old thread but I just was looking for the same answer you were and wanted to share. That type of li-ion (rectangular with a hard metal case) is a prismatic cell. http://www.powerstream.com/liprism.htm
I hope you found this out some time ago but if not here you go.
