    I just calibrated my battery...

    I'm at 72% health and 284 cycles. Just wondering if that will get me a replacement.

    Just extrapolating, I expect to hit about 70% by 300 cycles. Isn't the thing rated to hold 80% by 300 cycles, at a minimum?

    Plus I've taken really good care of my battery. So if thats right, I'm calling. Just want to double check first.

    Thanks.

    I think it is 80% within 300...which means you should ask.

    Yeah return it. Apple should learn how to make batteries that actually last a while.
    I know so many people with MBPs and battery problems. My own also is broken now, not sure they'll replace it because it was already over 300 cycles. Next time I won't bother and just get one from FastMac they are guaranteed to last.
