[QUOTE="EndlessMac, post: 1093079, member: 140470"] The misconception is that calibrating a battery makes it healthier. All it does is make the battery meter more accurate. If you don't care about the accuracy of your battery meter then you technically don't need to calibrate. You should not be calibrating more than once a month. From what I have read Lithium batteries like being drained partially rather than frequent full drains. I have a PowerBook that is about 7 years old and it's still has the original battery that works. I just don't leave it plugged in all the time. If you use your laptop as a portable then that happens naturally but there are a lot of people who use their laptops as a desktop though. I don't believe you have to do that to calibrate the battery. All I do is fully drain the battery and then plug it in right away when it goes to sleep. I then keep it plugged until it is fully charged. My battery meter is pretty accurate when doing so. As mentioned don't do this more than once a month and possibly longer if you notice your battery meter is still accurate. [/QUOTE]
