FAQs

Is it worth repairing an alternator?

Yes, repairing an alternator is often worth it if the issue is minor, such as worn bearings, brushes, or wiring problems. However, if the alternator has extensive internal damage or is older, replacing it may be the more reliable and cost-effective choice.

What is the lifespan of a car alternator?

Most alternators last between 7 and 10 years or approximately 80,000 to 150,000 miles, depending on driving conditions and electrical load. Regular maintenance and timely belt replacement can help extend the life of your alternator.

How long will a car run if the alternator is bad?

A vehicle can only run for a short time when the alternator fails—usually anywhere from a few minutes to an hour—before the battery dies. Once the battery’s stored power is depleted, the engine will shut off, and you will not be able to restart the vehicle.
