Hey yall just wondering if anyone else has had the same problems as me.. Well lets start with last week my girlfriend took my car out to the store and when she parked it she left the lights on for a total of 10 min. and the batery went dead so she had someone push her and then catch the car in gear. Now she drove home and told me about and I really didint believe her becase the car started right up for me and had allways been fine.. Now yesterday I took the car out and left the lights on for a total of 15 min max and the battery went dead again ( i had to jump it in gear) Now I am guessing either the battery is bad or the alternator. I leaning more towards the battery because after I got the car running once I got home the car starts up just fine and has since yesterday.. Sorry I wrote so much but has anyone else ever had any problems with their batery I am not sure if it is but it might be the original batery in the car....
