Simple problem sounds like. You Have an Very Bad alternator and a Very Good battery. A good battery will charge itself while it sits. You are driving your car and draining your battery, not really bad but enough that you are having to jump it once a week. I would replace that alternator before you need to replace that battery too. Your battery is already getting worse, as it is no longer able to support the load of the drivetrain.

I would throw a voltmeter on that battery, have a friend start the car, leave it in park and rev the engine a little, or rav it (i know, i couldnt let that one die) if your voltage dips, bad alternator. a good alternator with spike voltage when RPMs increase, as it is essentially a generator.

its easy. do it. i bet it is your alternator. i bet if you drove your car on a long trip, it would eventually strand you like when the aliens land (space aliens, not illegal aliens) in the movies.

And if you do not have a volt meter do this:
Sit in the car, buckle up. Press the trip reset for 15 seconds. Menu 1 will appear. Let go of the trip button. Look at the numbers that are displayed. And count them up. Then press the trip button for 5 seconds until menu 1 goes away and then release it and press it again really fast. Then release it again and press it really fast. Do this until you get to menu 19. once you are at 19 wait for a few seconds and it will say CODE. press the trip button until the number you calculated earlier is displayed. Then press the button for 5 seconds again. then do the quick press and release thing until you get to menu 9. Then it will give you a read out of the volts.
