When you aren't able to start your vehicle in the morning when you're headed off to work, it might not be the battery that is the culprit. You may be having an issue with your vehicle's alternator. There are some ways to tell if the alternator may be the problem.
Usually, you will try to jump start your car if a dead battery is suspected. If you jump start the car, and then the battery dies right away after you remove the jumper cables, the alternator is probably malfunctioning. If you've noticed that your headlights or interior lights are dimmer than normal, that is a sign of a poor alternator. If you hear a grinding noise under the hood, that might be the alternator.
