    My 15" MBP is now all of 5 months old. I generally keep it plugged in, but over the last few weeks or so, I've noticed that the maximum capacity of the battery keeps going down.

    I use an application called coconutBattery to occasionally take a peek at what's going on. Anyone have any ideas?

    You only have 8 load cycles. That's bad for a 5 month old battery. You need to use it. Have you calibrated?

    Since you won't be able to use your computer for 5 hours during calibration, you may want to do this step when you're asleep ;).

    Generally using a battery helps. One cycle a month is a minimum according to Apple's site, but once a week may be safer.
