On a battery for X6*s

What do yo think about this battery?

As far as I can tell it is supposed to be a battery for ThinkPad Reserve edition. Does it fit X60s or X61s as well? And - what is most important - how do you thing whether it is really an original Lenovo battery?

The description claims it is.

And - what is most important - how do you thing whether it is really an original Lenovo battery?

You can't. At least not with certainty. It is, however, marked with the "Lenovo" logo, so at least it's not blatantly a knock-off.

In my experience, batteries on eBay that carry the official markings are usually legit -- eBay's cracked down on counterfit items quite a bit lately, and I suspect that it's just not worth the risks for most sellers.
