Coconutbattery shows my air is 25 weeks old...

I just got it yesterday!!

Also, my battery capacity is almost 400 less mAh than I have seen in my friends same model MBA.

What should I do?

Coconut battery is also notoriously buggy and often inaccurate. You should just use your computer as you would normally. The difference in capacity may be correct, but not every battery will be exactly the same.

Even if it was, it isn't like it has been used for the last 25 weeks. It might have been an early production. If so, it's been sitting in a box waiting for you since then.

Remove coconut battery and enjoy your macbook air. Follow some simple best practices with your battery, and be done.

fyi. I believe coconut battery has not been updated with the latest serial numbers of the airs, which is why your date is all messed up.

There is/was/has been a problem with Coconutbattery showing the Age of MacBooks.

According to the app my MacBook Air was built in early February. Which would be damn near impossible since the Intel Sandy Bridge 2677M wasn't even shipping then.

I wouldn't worry about it. Every laptop I have used over the last 3 years has been strangely old according to Coconutbattery.

When you are next to your magsafe, plug it in. If you are always near the magsafe, then just unplug it every so often (once a week is fine). Every month or so, run it down for a full charge.

The two main things to consider is you want to exercise the battery every so often, and you need to calibrate OS X every so often (there are instructions on how to do this on the apple site).

I personally use my macbook air closer to how I use my iPad. Unplugged a lot. By the time the battery is used up, either I'll be happy to give apple a couple hundred bucks for a new one or it'll be time to upgrade. =) 1000 cycles is a lot (3 years of once a day). I don't want to have the toyota prius symptom with this thing (where people are always watching the batteries instead of just driving normally).

CoconutBattery reports data gathered from your very own computer, it doesn't make anything up. The time shown in the app simply shows how old the BATTERY is, not the actual computer.
