WTB: x201 Tablet 4 cell battery (FRU 42T4657, 43R9256)

[wea]

Hi,

I'm looking for a 4 cell battery for my new x201 Tablet, since it came with an 8 cell, and I am looking for something lighter.
The FRU specified for the x201t is 42T4657, and the FRU specified for the x200t is 43R9256.

Please let me know what you have, when it was first used, and how many cycles on it.

Thanks!
