Hello, 

Thank you for writing in. There are a couple of things that may be causing your issues. First, if the battery dies after you turn the car off, then there is something drawing power from the battery when it shouldn't be. Once the battery is jump started, it has enough power to crank over the starter. Secondly, the alternator may not be charging the battery like it should when the car is running. At that point, you are not able to use the battery to start the vehicle. If the battery and its charging system is fine, then you have a bad starter. Only further testing will tell. Good luck!

A new car battery can die repeatedly for several reasons.

1.  Check that the battery connections are tight and not corroded

2.  Make sure the headlights and dome lights (any and all interior lights) are not left on

3.  Have the alternator tested to make sure it's working correctly to charge the battery when you are driving

If none of these situations are causing the problem, then you may have a parasitic drain somewhere in your electrical system.  Diagnosing a parasitic drain can be challenging, time consuming and expensive, unfortunately.
