How Long Will a Car Run With a Bad Alternator?
My car sputtered to a stop in the middle of a busy intersection. I had no idea what was wrong, but I knew I needed to get out of the way of traffic. I managed to push my car to the side of the road, and then I called for help.
When the mechanic arrived, he took a look at my car and told me that the alternator was bad. He said that the alternator is responsible for charging the battery, and without a working alternator, the battery would eventually die and the car would stop running.
How Long Will a Car Run With a Bad Alternator?
The answer to this question depends on a number of factors, including the age and condition of the battery, the type of driving you do, and the weather conditions.
In general, a car with a bad alternator will run for a few minutes to a few hours. If the battery is new and in good condition, it may be able to power the car for longer. However, if the battery is old or weak, the car may only be able to run for a few minutes.
If you are driving at night or in bad weather, the car may run for even less time. This is because the headlights and other electrical components draw more power from the battery.
Symptoms of a Bad Alternator
There are a number of symptoms that may indicate that your alternator is bad. These symptoms include:
- Dimming headlights
- Flickering or malfunctioning electrical components
- A growling or whining noise from the engine

What to Do If Your Alternator Goes Bad
If you think your alternator may be bad, it is important to have it checked by a mechanic as soon as possible. Driving with a bad alternator can damage the battery and other electrical components in your car.
The mechanic will be able to test the alternator and determine if it needs to be replaced. If the alternator is bad, the mechanic will replace it with a new one.
