That sounds like a bad battery.

To be certain, use a battery utility, such as [http://www.coconut-flavour.com/coconutbattery/|coconutBattery] (for Mac) or [http://www.3u.com/|3uTools] (for Windows). It will tell you what the health of the battery is. Anything less than 75% of design capacity will require replacement.
