        I disagree, sorry – asked someone on the Apple genius bar the same question and he said to charge and discharge it, or else the battery cells weaken, which decreases battery life. he said, though, that if you use it a lot, 3 times a week is enough to drain and refill the battery.

          What you are talking about is calibrating your battery for longer life. While I agree that doing this every once in a while is a good thing, doing it 3 times per week for no reason is NOT. That would run it through needless “cycles” and it won’t last as long. Apple recommends doing it once every one or two months (http://docs.info.apple.com/article.html?path=Mac/10.6/en/9036.html). Of course for most MacBook users they do it once a month through natural use, so it isn’t necessary to do anything special.
          I maintain that “calibrating” the battery once a month vs. natural use, where it might get drained once a month or more anyway, is about the same, give or take a few percent. But people stress about getting every bit of life out of a battery way too much.

      Besides the info in this video, I’m not sure there is much to say. I’m not a big believer in many of the techniques people use to extend battery life. I see people wasting tons of time and effort trying to get 1 or 2 percent more. I think people should let the hardware and software in their MacBooks handle it, and they should use their Macs to optimize their time and energy, not the battery’s time and energy.
