    I don't need to calibrate...just need to know if I should charge first before using it....didn't know if I'm supposed to do a full charge to better battery life?

    But not calibrating it can. It's very important when you get a new device.

    That's what calibrating it is. Basically charge it up all the way, keep it charged for a few hours, then use it until the computer dies. Charge it back up to 100% and you are good to go.

    Actually, using it is part of what hurts it. A battery's life decreases from overuse or underuse. Calibration and then finding the medium between overuse and underuse will increase the life of a battery.

    One cycle isn't going to hurt anything and the lack of using it can deplete it as well. If you just bought it at 0% charge and plugged it in and used it, it would make little difference versus charging it to 100% and then using it.

    Right, but that one caibration cycle (charging it up, keeping it charged, letting it die, then keeping it dead for a little while, then charging it back up) sets limits for the battery so it can work to its full potential. It really does help, and its a simple thing to do that doesn't take long, so I think its just better to be safe than sorry

    Batteries on the MacBook are only covered under warranty for one year, or 300 charge cycles (whichever comes first), because that's about how long they will work under normal use. If you plan on having your computer for more than a year, you will see it start to die. It happens gradually, but in time it really will be noticeable. I still think that it's a very easy thing to do. It only takes one day and can really make a difference for your battery.

    But that wasn't what he was asking. On his first charge, anything he does to the battery is negligible.

    The calibration charge cycle should be the first cycle.
