Just bought my 11" sandybridge mba and coconut battery 2.7 shows 98% maximum capacity and that the computer is 25 weeks old.
I've gone through a couple of charge cycles and calibrated the battery once.
Anyone else has this?

Mine says 25 weeks old and 97% capacity. I too was perplexed by this.

It's probably an issue with coconut battery itself.
I remember on my brand new 17" MBP last year, CB was reporting the battery was like 170 days old. Impossible. It was widely known as a bug with the app.

Don't know what you guys expect, its not like they produce these batteries they instant the assemble the machine. Most of these batteries were probably left over from the 2010 production. The % remaining doesn't matter right now, it will fluctuate a lot from 95-100% your first few hundred cycles.

So the question is, are the batteries actually half a year old or is it a bug with coconut?
According to wikipedia, lithium-ion batteries loses capacity over time:
Not that it affects anything in reality, but it bugs me if I got batteries that started declining in capacity before I even bought it (day at release).
