You get your new Macbook Air out of the box, it has a 80% battery charge.

What do you do?

No conditioning is necessary. Just plug it in and fully charge it. Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug at any time, regardless of the charged percentage. Just make sure you don't run on AC power all the time, as your battery needs to be used regularly to stay healthy. This should answer most, if not all, of your battery/charging questions:

AppleCare support recommends that if you leave your Mac plugged in most of the time, unplug it every 2 or 3 days and run on battery down to somewhere around 50%, then plug it back in. That keeps the electrons moving.

Isn't this considered a form of calibration?

No, it's simply exercising the battery, and only suggested if you don't regularly run on battery power. The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration (http://support.apple.com/kb/HT1490) like the removable batteries in older Apple notebooks.

For the steps to calibration for older Mac notebooks, read the CALIBRATION section of the Battery FAQ.

Ok then. So what kind of "exercises" other than the one I quoted, need to be done?

I'm coming from a Powerbook battery that only has 655 cycles but can't last longer than 20 seconds without the AC cord. The experience has made me very paranoid about batteries and making sure I'm doing it right.

None. As long as you run on battery power regularly and don't run exclusively on AC power, there's nothing else you need to do. Just relax and enjoy your Mac.

Mac batteries have changed; three years ago they were rated for 300 charges, but today they are rated for 1000 charges, so with a new MBA the 655 charges wouldn't be a problem.

The rule: Don't use the batteries unnecessarily (but don't go panicky about it, because you have 1000 charges). You can leave the MBA plugged in all the time, but then you should run it on batteries about once a month.

That's good news. 1001 cycles until 80% is really hard for me to believe. Is yours actually like that?

I think my Powerbook was at 50% by like 200 cycles.

Then again, I don't exactly keep my toys long enough to see how the Battery is. LOL My 32GB BlackBerry PlayBook currently holds that record and counting.

I will probably do something like this.

Having any portability whatsoever will be soooo refreshing. I've forgotten what it feels like. I've had to carry my cord around for a long, long time. I've just gotta find better things to do on the internet than Macrumors to make it worth it. :p

That is not necessary and not recommended by Apple. You're putting unnecessary cycles on your battery and it won't have any effect on its health or performance.

If you do, you're putting unnecessary cycles on your battery. There is no conditioning or calibration necessary or recommended by Apple for current Mac notebook batteries. Old habits seem hard to change for some people.

Sadly, it is posts like this that too many people who desperately think they have to do something, read and follow, even though no explanation is included for why the poster does this, where this information came from or if it applies (it doesn't) to an MBA. Posts with links to Apple are ignored while people follow undocumented instructions from posts by strangers. The clean install threads are similar. No documentation yet people blindly follow the advice, spending hours rebuilding their Macs, occasionally messing them up, all because the OP said it resulted in a 'snapper' system.

In my defence I didn't say it's necessary nor it's the way to properly condition the battery. I just got used to it and as I said, I don't keep my toys long enough.

I thought I posted where I got this tip from, I got it here long time ago probably when I first bought my iPod.

No one should be disparaged for asking a question. Offering advice without having facts is another matter, as doing so can mislead others.

It sounded less like any "advice" was given and more like someone describing how they use their devices. Pointing out inaccuracies is good, but it was unnecessary to try and make an example out of the post that was clearly not suggesting to "do as I do".

You're right, I don't care. It's just one person's point of view. I don't just want the correct answer - I want to hear them all. Good, bad, wrong, right, crazy, mainstream, and even yours. If you only allow the "correct" answer, you may miss something that is really good. It would also make this place very boring.

The problem with wrong answers is that some are naive or uninformed enough to believe them. Missing a wrong answer is something that anyone can benefit from. While you may not appreciate this, there are countless others who come here looking for help and would rather not be confused by people posting false information.

Unfortunately this question is fundamentally pointless. You should use your computer how you want to and stop worrying about your battery. Batteries are easily and cheaply replaceable. They are covered by the manufacturer to a standard that every non-defective battery will meet (1000 cycles, 80% capacity, 3 years) regardless of how regularly you "care" for it. And finally, you will never be able to correlate your battery "preservation" measures to any quantifiable increase or decrease in battery life.

Stop worrying about your battery. It's pointless.

Maybe I'm just naive, but I'm really impressed that you had a Powerbook battery that went 655 cycles...Dude, that's a lot for that battery's generation, and I might add, much more cycles than you would see on any comparable PC at the time and even with many now (for example, this $3000 Alienware computer I'm typing with now cannot last more than 45 min w/o power and it's basically brand new).

NiMH do not have a memory effect either. Batteries that used to have a memory and needed to be fully discharged often were nickel cadmium.

And therefore also means that correcting everything in here is absolutely not necessary and not contributing. The only thing that does is create an image of the poster not liking that others don't do as he says. Which in turn will work against him and his information (people won't take him seriously nor read his posts). Not a very wise thing to do!

I personally have never done any battery maintenance ever and the batteries still last for a loooong time. The battery in my 2006 MacBook is insane, it is still able to run for like 3hrs. We're talking about a 6 year old machine here! However, my early 2008 MBP has the most crappiest battery of them all, it doesn't seem to last longer than 1.5 years (and I'm not the only one). I learned a long time ago that the li-ion and lipo batteries which are used in notebooks will do whatever they want. Calibration or any form of battery health improvement won't work. Just use the machine as you see fit.
