Unhappy Macbook pro shutting down while still at 80% battery charge

Hi, my macbook pro has been shutting down quicker and quicker and now only lasts for 10 or so minutes on battery power before shutting down without warning. The battery lights still indicate it has over half power but if I try to start it up it just shuts straight back down again.

When I start it up when connected to the power cord is usually indicates that i still have 75-85% battery power so I'm not sure what's going on, or if it's a problem with the battery or machine itself. Any advice would be greatly appreciated.

If its in warranty talk to Apple.
If they have to tell you every day they are fair you can bet they arent, if they tell you they are balanced then you should know they are not - Don't Hurt me

Sounds like the classic behavior of a dead battery. Have you tried this?:
