Query: Works great, but batteries die too fast!

I got this battery exactly a year ago - in December 2009. Now it is dead. It can't hold a charge for two days when you even do not use a cell phone. It goes from full bar right to red just from opening the cell phone and dial a number. One "Hello" and you have the signal that the battery is low. It maybe worth its $5 dollars that I paid for it. But not more than that.
