Why does my battery keep dying?

I would like to learn if I need a new battery or could there be another problem?
I took the battery out of my car and took it to a auto parts store. They placed it on a machine and said it was still good but still needed to be charged.
So I went back and got the battery and placed in back in my car. It ran for a day or so and when I went to get in my car and crank it up it would not start again.
Why would this happen? Thanks.

The problem is that the alternator is not charging the battery.
It may be that there is a problem in the alternator prohibiting generation of enough electricity or not allowing enough electricity to pass through to the battery to charge it while the engine operates.
Or, it can be that the voltage regulating circuitry that controls when and how much electricity is sent to the battery while the engine is running.
