the volt meter shows 14 volts. Why? The battery dies next time i turn off the car (even after driving for 20 min).

Default Battery = BAD, Alternator = Good.
Once the car gets started, the alternator now provides the juice.

Bad reading, your car is running so shanelu97 is right.

Default It takes ~20 mins of driving just to replace the charge lost from starting on a good battery.
That is partly why short trip cars go thru batteries quicker than long trip cars.

Default If you do a search - this answer has been posted many times
To charge a battery you have to have the voltage higher in order for there to be electron flow. Thus the alternator will put out 14 volts or higher to charge the battery.
