Several possibilities I know of:

  1. Old battery. This is the most likely IMO. When the battery gets old, it no holds its charge. See this post for more details on battery testing.

  2. Corrosion on Battery leads. Unlikely, but corrosion could actually be causing a energy leak, meaning that the battery can't deliver current like it should. Check to make sure you have a solid connection on your battery

  3. Parasitic drain. There could be a parasitic drain on your car's system. Check out this post for more info on parasitic draws.

Hope you can nail your problem and get it fixed!

I suggest you check for any device / circuit using energy while the motor is off. Possible culprits include the diodes in the alternator, glove box or interior lights not turning off or even the radio...
