I think my Unibody Macbook's battery is bad

[ndassassin]

Hi guys, I've had my Unibody Macbook 13" since February 2009 and the health says 97%. However, my battery sure doesn't last as long as it did when I first got it. If I am just watching about 40 minutes of a tv show in divx format the battery goes down to around 55% from 100%. To me it seems it should last much longer than that. If I stream my slingbox through Slingplayer for about an hour over wifi it goes down to below 15%. Does it sound like my battery is bad? If so, what is the best route to go to get a new one? I am not close to an Apple store so I really can't walk in to one. I would prefer to not have to send in my entire Macbook since it is my main computer.

Download and install Coconutbattery and post the results.

I will try that as soon as I get home from work. Thanks!

Have you calibrated your battery recently? It could be that you're not getting an accurate reading on the percent remaining.
