I bought a a MacBook Pro not so long ago, I charge my battery all the time. Before when I was disconnect it from the plug it would die in 30 minutes or so. Now if it disconnects my laptop doesn't warn me that it's dying, says it has 100% battery and turns off. What do you think this could be?
So, that's it, time to throw in the towel? Read the Apple website, and the appropriate technical article. On the other hand, lazybones, read this:

Your battery is in good health, but it apparently isn't supplying power to the computer for some reason. Make a Genius Bar appointment at your nearest Apple Store and have it checked out. There is evidently a hardware problem.
I am experiencing similar problems.... my battery is apparently fully charged, but when I run it of the battery, I get less than 20 minutes. I got my MBP at the end of August 2007.... it contains the original battery, and my cycle count is only 86... I tried to reset the SMC but that did nothing!
