    Is this normal? This is the original battery that came with my MBP. I'm kind of hoping that I don't have to buy a new battery.

    I did notice yesterday that I got the low battery warning (~10%), then it went down to about 5% and then immediately shot up to ~30%. Might these two be related somehow? Does this mean that I should calibrate my battery?

    Calibrate your battery.

    If this has no effect, you may qualify for a warranty battery replacement if your computer is less than 1 year old.
