Over the past four weeks my Macbook Pro battery's performance declined precipitously, and I think this is the cause. I tended to leave it plugged in whenever I was at my desk, which is most of the time. Got to the point where the MBP wouldn't last more than 5 minutes unplugged. Just received a new battery and all is well. Think I'll be giving this technique a shot.
