Have you battery fully charged and comapre these two:
Charge remaining (mAh):
Full charge capacity (mAh):
Your Mac appears to have the built in Battery. These batteries are advertised as having a 1000 cycle count. You only have a cycle count of 526.
With this information you can talk again with Apple Genius
If you are under the extended warranty I would not give up hope it may be covered??

You can also try resetting the SMC http://support.apple.com/kb/ht3964 if the Battery is not charging when it should be.MacBook Pro (15-inch Mid 2010), OS X Mountain Lion (10.8.2), 2.4GHz IntelCorei5 320GB HD 8GB RAM

If your MBP is running hot and the fans are spinning, that may account for the short battery life that you are experiencing. You may be experiencing a 'runaway application'.
If you wish post images of the following::
From the Internet download iStat pro. It shows the fan speeds and internal temperatures of your MBP.
Activity Monitor. Select 'All Processes' and set '% CPU' to show values from high to low.

I checked my activity monitor and followed your steps. Are the % meant to constantly change and adjust? They seemed to change constantly and wouldn't settle on one %. Not sure if I am doing something wrong? But from what I could tell the highest number was 2.3%ish.
Thanks for your help. Much appreciated!

The display in Activity Monitor is always in constant flux reflecting the tasks that the OS is performing. However the applications that use the most resources will always be shown on top if you have set the parameters as I indicated earlier. These are the ones that are of interest which may allow us to identify the problem.
You are doing nothing wrong.

The Activity Monitor display shows nothing abnormal and the MBP fans under these conditions should have been at the minimum or default level and the MBP case temperature should not be hot.
If you MBP was experiencing hot conditions with high fan speeds, repost the Activity Monitor AND an image of the iStat pro display which I mentioned earlier. In addition, you might run an Apple Hardware test which may develop some clues to the problem:
You may have to use OPTION - D to start the test.
It may be that part of your problem with short battery life is attributable to how you have your MBP set up. This support article may be of help;
I note that your battery cycles put it well into 'middle age' and cannot be expected to perform as it did when it was new. In addition, if you are relying on the battery display in the menu bar which shows time remaining, be advised that is one of the most unreliable measures on your MBP. To get accurate battery life measurements, one must use an independent timer.

Thanks for all your help. I took it to Apple (Genius Bar) and she advised me that my battery is now middle aged and a high use of the battery can decrease its function. All tests can back as clear. She did say the heat and fan issue are normal? My memory is terrible and I cant remember if it was this hot when I bought it back in Dec 2010.
