did I claibrate correctly & monitoring the process use caffine or sleep modes?

    I just ran my battery down to calibrate, except that about 1/4 through the process at about 60% I turned on caffeine & had it run down to 3% & got the battery reserves warning. It is now just shut off.

    If one does a calibration without using the sleep mode, after the low battery warning, does one just shut their mac down when it gets to about 2-3%? & does one have to wait 5 hours before plugging it back in to charge?

    the whole process could be a little awkward as I cant be around the mac the whole time to monitor the calibration process, so I most likely will do this overnight, but the trouble with this is I may sleep through the low battery warning or miss it & it goes down lower than 2%. Should I just let it go to rock bottom or would it be harmful if it goes until the mac just shuts off?

    The calibration steps in the Battery FAQ are very clear.
    This FAQ has been posted in several other battery-related threads you started. You don't have to do anything at the battery warning... just let it die. To calibrate, it needs to drain to 0%. This should answer most, if not all, of your battery questions:
