I would not worry about it. It will vary on it's health status. The battery is supposed to be good for 1,000 cycles. If it drops below 80% before 800 cycles then you may have something.
Also Apple can replace your battery with a new one for just over $100. But I doubt you will need to worry about that for another 800+ cycles.
Yea, I guess your correct, right when the new Air was launched Apple left the old battery info on their website, it has now been updated and changed, sorry for any confusion.
if you're battery carks it within the warranty period, I'd say that Apple will either replace it free of charge or at least pro rata the cost of replacement.
as someone's already mentioned, we're only talking a hundred bucks.
"AppleCare WILL, however, extend the defective battery replacement period from 1 to 3 years"
and if you don't get a reasonable number of cycles before its capacity drops below 80% then there's a good chance it could be seen as 'defective'

96% Health
I think there are a lot of issues with the new MBA. It has the worse battery life out of all my previous Macs, even when I'm using it lightly. There is something either wrong with Lion or the way they built the 2011 MBAs. I waited for 10.7.2 to make it better, but it really hasn't. The rapid usage of battery is why your battery health has deteriorated so quickly, I go through 1 cycle in about 4.5 hrs. NOT the 7 hours they advertise. This is all just browsing with some background apps. There is very long thread on the apple support boards about the MBPs and Lion and horrible battery life.
So here are my specs:
i7 core 13" MBA 2011 4GB RAM 256 SSD - after 10.7.2 upgrade
Some battery stats (typical browsing, word running in background, mail up)
13:00 59%
13:46 42%
14:07 34%
This would just net me 4.5 hours total.

It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.
This should answer most, if not all, of your battery/charging questions:
I'm at 90% with 168 cycles. Was at 94% for quite a while, but has dropped down to the 89% to 91% range lately. I'm not worried - more concerned about getting 7+ hours of daily use out of it, especially while traveling. Fluctuations in percentage of health don't mean much until you get to 80%, when you'll start to see real time use negatively effected.
I'm a heavy battery user. After a little over a year my battery capacity floats between 88 and 92%.
It will be interesting to see in the next year or so as I get closer to 700 cycles how it holds up. My older laptops tended to get new batteries in year 2, but if Apple is correct and I can get 1000 cycles out of this battery then I may never need a new battery.

You can use apps to do this or you can use the Apple OS. How? Click the Apple symbol on the top right --> About This Mac ---> More Info... ---> System Report --> Power on the left and look under: Health Information.

$100 for a new battery isn't bad at all... I've used mine for 7 months and I'm at 96.9% health and 26 cycles, so I may never need a new battery either (I tend to buy new computers every 3-5 years). Interesting.
Have you let the battery get through a full cycle yet? if not, I would suggest letting your battery run a full cycle at least once every month to help retain the health of it.
If they run on battery for a few hours every few days as recommended in the Battery FAQ, they'll average more than one cycle per month.
I keep having the little devil on my shoulder telling me that I'll get 100% battery health if I drain my Air's battery down to 0 and back up. lol. Hard to get out of the old Ni-CD/Ni-MH days...
What counts as a "Cycle" anyway? What is a "Cycle" and how do you know you'll get one?
