    Looking at the information in this link, I get the impression that the internal battery of the macbook air requires no calibration at all. Am I right?

    (All) Batteries require calibration from time to time so the percentage remaining is accurate.

    The vast majority of Mac owners don't pay any attention and don't bother. Some people do extensive calibration and pay attention to every % tick. Where you fall on that spectrum depends on you. I'm in the former group.

    Calibration doesn't improve your battery life/health, it just gives you a more accurate reading. For good readings, all batteries need to be calibrated.

    You don't HAVE to do it, if you are only using your laptop a few hours a day then there really isn't much point. Personally I don't calibrate mine, because I don't use it for anywhere near enough everyday for it to every run out of battery.

    Apple's position is a new battery does not need to be calibrated.

    OCD seems to rule most here with regard to 100% displaying vs 99 or 98%.

    There a lot of worrying around here ... don't see that changing!

    If you don't care about the exact accuracy of your battery gauge, you don't need to run a calibration cycle. Many people don't care, as long as their MBA runs for a reasonable amount of time between charges.

    I don't run LiIon battery calibration cycles once a month, as some suggest, because the maybe 1% change in battery capacity over that time is far too small for me to care about.

    The built-in batteries of the new Apple notebooks come pre-calibrated and do not require regular calibration. This should answer most, if not all, of your battery questions:
