Late 2011 Macbook Pro Battery Life SUCKSS

Just got my refurbished Macbook Pro (Late 2011) model and the battery life is ridiculous!

With screen brightness belowed halfway, bluetooth off, just browsing online over Wifi and I get 2:20 minutes of use.

I just opened Aperture for 30 minutes and it went below 50 percent! I'm about to go to Apple and let them know. Not near the promised 7 hours AT ALL.

Is this considered normal on Mountain Lion right now? I got a battery health app and my capacity is fine. It says I should have over 5 hours using the web but I don't even have half that. What do you guys experiencing?
