Hi ,

I have a 1999 Ford Mustang. It was lying idle for a few weeks and it was unable to start on its own. So I got it jump started today. It started fine and I drove it around for 30 minutes. I thought that was enough for battery to come back to life. After 30 minutes I came back home and shut it off. Now when I try to start it , it does not start.
What can be wrong? Should I get it jump started again and drive for a longer duration? Or do I need a new battery?

What you need to do is check to see if the
alternator is working. Jump the car to get it
started. Remove the jumper cables. Put a
voltmeter across the bat terminals. If the
alternator is charging it should read around 14
volts. if it does and your battery is still
not starting the car then the battery is
bad. If you are reading less than or around 12
volts then the alternator is bad.

I would also fully charge the battery with a charger. The alternator is only there to maintain the charge. Not to charge the battery from a dead state. IMHO
