Can a dead battery cause a car to die while driving?

The car battery is one of the most crucial components of the car. It plays several important roles, including providing initial power to start the engine, and also powers all electrical components of the car, including the wipers, air conditioning, airbag system, and headlights when the engine is switched off.

The last thing that any motorist would want is to have a dead battery while in the middle of the road. So can a dead battery cause a car to die while driving? keep reading to find out.

So, can a dead battery cause a car to die while driving?

YES, a dead battery can cause your engine to stop running while you are driving. When your car battery suddenly dies off while driving, the alternator, which supplies the vehicle’s electrical needs and also charges the battery will be overloaded and that will make the car stall.

This aspect is true, especially for modern vehicles that cannot run at all when the battery is dead. This is because most modern car electrical components are interconnected and if the battery is dead, then that is an indication that there is a problem with the vehicle’s electrical system and that will make the engine stop running.

So when you notice that there is a battery warning on the dashboard, you should move your vehicle off the road immediately and check the issue because it will at some point stall.

Most motorists think that the only problem with having a bad battery is that the car will not start. Yes, it is true that your car will not start when the battery is dead.

However, if your car battery goes bad when the engine is not running, the car will continue to run but it will be at high risk of stalling out.

This is because when the battery is dead, then it means that it is not providing much-needed power to the car. As a result, the alternator, which also powers the car’s electrical components will have to work harder to keep the engine running. And when the alternator overworks, it stresses the engine and if the problem is not fixed quickly, the car will stall out.

What could cause a car to die while driving?

There are multiple reasons that could cause your car to die while driving. They include:

Bad battery

One of the most common reasons that may cause your car to stall is a bad battery. As explained, a bad battery will force the alternator to work harder to keep the engine running. This will, in turn, stress the engine causing it to stall.

Too much moisture in the gas

Your car can also stall while driving if the gas has too much moisture. Moisture in the gas will cause fuel not to burn properly thus disrupting engine performance and eventually causing your car to die.

Issues with the distributor cap

The distributor cap is the cover that protects the internal parts and also holds contact between the spark plug wire and the internal rotor.

This component plays a vital role in ensuring that the engine runs smoothly. If the rotor becomes clogged or if the wiring is not well connected, it may cause the spark plug to misfire thus causing the car to stall.

An issue with fuel pressure

If your car only stalls when going uphill or downhill, then it could be a result of the fuel pressure problem. If your car is not able to pump fuel to the engine on time, then it will stall.

What happens if a battery dies while driving?

If your car battery dies while driving, your car’s electrical system will be disrupted and that will cause the car to stall. It is important to note that the car will not stall immediately when the battery dies but if you ignore the problem, then it will eventually stall.

Besides disrupting the car’s electrical system, the alternator will also be overloaded when the batteries die and it will in turn stress the engine causing it to shut off when the pressure is too much. So, if your car battery dies while driving, your car will be at high risk of stalling.

Can remote start mess up your battery?

A short answer is YES, but only if it is faulty. A bad remote starter can drain your car battery quickly without your knowledge. If your car did not come with this device and you are thinking of installing an aftermarket model, you should think twice because it will drain the battery as well as disrupt your car’s electrical systems, especially if it is installed properly.

Will a car still run with a dead battery?

YES, the car will run but not for long. If the problem is not fixed quickly, your car will at some point stall. This is because a dead battery will force the alternator to overwork, and pile more pressure on the engine, forcing it to stall.

Final thoughts

If you have noticed that your car battery effectiveness has reduced drastically and you are worried that it will soon die, you should change it immediately.

This is because if the battery dies, then your car will be at risk of stalling while driving, which is something that you don’t want.
