    Unhappy MACBOOK Battery

    Hey guys, i am getting conflicting advice from the internet and Mac Staff.

    The Battery on a mac, should it always be on charge?? i know on a WIndows Laptop that leaving it on charge ruins the battery, will this happen with a macbook.

    I use a prog called CoconutBattery which states that in 5 months my battery orginal capacity was 5020 mAh it is now only 4692 mAh

    How long did you have it? Lithium-ion battery's charge dimishes over time... You might want to look up how lithium-ion batterys work.

    (And no, charge cycles does not, or should not affect battery charge.)

    well your's is a bit off,... mine is still at 4810Mah after nearly 1.5 years...

    anyways apple's battery replacement policy really sux:
    Your one-year warranty includes replacement coverage for a defective battery. You can extend your replacement coverage for a defective battery to three years from the date of your notebook purchase with the AppleCare Protection Plan. However, the AppleCare Protection Plan for notebook computers does not cover batteries that have failed or are exhibiting diminished capacity except when the failure or diminished capacity is the result of a manufacturing defect. Apple offers a battery replacement service for MacBook Air and 17-inch Aluminum MacBook Pro. You can purchase replacement batteries for late models of Apple notebooks directly from the Apple Store.

    I tend to just keep it plugged in. However, according to what I learned in chemistry and what Apple's website and what Wikipedia says is that it should be cycle-independent
