Macbook battery dying

My laptop battery has been steadily losing capacity since I bought the machine. Right now, I have about 60% of the original capacity remaining, according to coconutBattery, which translates into about 2 - 3 hrs of battery life. Apple had a replacement program for Macbook batteries, but my battery had about 450 charging cycles on it, and the replacement program requires less than 300 cycles. I still have almost 2 years left with AppleCare, so I am planning to go by my local Apple store and ask them if I can still get a replacement, otherwise I will have to shell out $129 for a new battery. I suppose I could keep the old battery as an emergency spare, so it is not a total loss.
