1. Not fully charged battery

Are you in a plight with not full charge in your car’s battery? Stuck up in a dilemma if you should drive any further or not?

2. Fully charged battery

The capacity of your car’s battery makes a call for the time your car can run even with a busted alternator. Have a 100% charge? Amazing!

Now you can make your run time elongated more than 30 minutes. However, the drive time could be about an hour as well. But this max time limit relies on the next considering point too.

Why not move to that!

Model of Your Car

How long can your drive with a bad alternator? An alternator can make its way up to 90,000 to 150,000 miles on average in terms of miles. But is the stated lifespan the same for the car alternators of all companies?

Well, an honest answer is hiding behind the services your car’s model claims to provide. Let’s check out three different models’ survival with a poor alternator!

1. Gasoline-run car (Old model)

When you’re driving a gasoline-run car in the daytime, there are chances to have a little less consumption of battery energy. It’s because you won’t be using the headlights.

Have a car of 1960s or so with a faulty alternator? No worries. A full charge battery drives up to 65 miles for 5-60 minutes.

2. Diesel car (Old model)

Compared to gasoline car, diesel cars don’t come with spark plugs. That’s why they are sure to save you ample charge. 

Hence with your old-time car, you’ve higher chances to run to a long destination for a couple of hours. Your only stoppage comes after running out of oil.

3. Latest Model

A brand-new car of the latest model adds a lot of complex parts and functions. Such as electronic displays, sensors, computing actions, and so on. Extra functions cost extra energy, meaning extra battery charge use.

That’s why it’s risky to run even a shorter distance with a failed car alternator. A short runtime may consume the battery faster than usual cases or older models. Be careful!
