    I read from the apple website somewhere that the battery on a macbook pro should hold a capacity of about 80% after 300 cycles. I'm at 270 cycles... and my capacity constantly hovers around 40%.

    Is this battery defective? Should I go to the apple store in my city and see if they will give me a new battery?

    I have applecare if that changes anything.

    I would definitely go to an Apple Store. That's unacceptable.

    Have you calibrated the battery recently, If so, did the capacity get any better?

    I would calibrate the battery a few times and if it makes no difference to the capacity, then I would go to the Apple store.

    i calibrated it about 3 times now in the last few weeks... and after every time it's actually getting worse.

    I'd take it to an Apple store and explain this to them.

    Take it to them before you hit 300 cycles or else you're screwed with that battery
