    Hi Guys,
    I remember reading a thread posted by one of the users on MacRumors discussing increasing battery life, One of the things that was mentioned was, once a month you should drain your battery then recharge to keep the battery at it's best. I'm wondering, if someone only uses their laptop as their desktop and doesn't take it out often, would it be better for the battery, to remove it and store it (at 50% charge) and just run straight off the mains?
    I'm just speculating here:cool:

    Running the computer on just the AC adapter and no battery will make the system slow down the CPU, as this will put an enormous load on the power supply.

    This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ
    No, it's not completely wrong. It doesn't put "an enormous load" on the power supply, but it will slow down your system. It is not recommended to run your Mac on the A/C adaptor with the battery out (Of course, this only applies to removable batteries).
