Othello: I know your 18650s are not A123. There are many different brands and types of cells that use this size, roughly 18mm x 650mm. It's a common lLi-on size.

I'm just pointing out that there IS a new 18650 size LiFe-po4 cell from A123.

So, there is the 2300mah A123 as found in Dewalt 36v packs, and a new smaller 1100mah A123 that are used in the new B&D 7v VPX line of tools.

There is also a chinese knock-off cells that some have mistaken for the new A123, but it's not the same.
