Can a Bad Battery Cause a Car to Stall?
Imagine you’re driving down the highway, and suddenly your car sputters and stalls. What gives? If you’re not sure, one possible culprit could be a bad battery.
Your car’s battery is responsible for providing the electrical power needed to start the engine, power the lights, and run other accessories. When the battery is weak or dead, it can’t provide enough power to the engine, which can cause it to stall.
Why a Bad Battery Can Cause Stalling
There are a few reasons why a bad battery can cause a car to stall.
- Insufficient power to start the engine: When the battery is weak, it may not be able to provide enough power to the starter motor to crank the engine.
- Electrical system malfunctions: A bad battery can also cause electrical system malfunctions, which can lead to stalling. For example, a weak battery may not be able to provide enough power to the ignition system, which can prevent the engine from starting.
- Fuel pump failure: In some cases, a bad battery can cause the fuel pump to fail. This can prevent the engine from getting the fuel it needs to run, which can lead to stalling.
If you think your car’s battery may be bad, there are a few things you can do to check.
- Check the battery terminals: The battery terminals should be clean and free of corrosion. If they’re corroded, you can clean them with a battery terminal cleaner.
- Test the battery voltage: You can use a voltmeter to test the battery voltage. A healthy battery should have a voltage of around 12.6 volts. If the voltage is below 12 volts, the battery may be weak or dead.
- Have the battery load tested: A load test can help to determine if the battery is able to provide enough power to the engine. You can have this test done at most auto parts stores.
If you find that your battery is bad, it’s important to replace it as soon as possible. A bad battery can not only cause your car to stall, but it can also damage other electrical components in your car.
Expert Advice
Here are some tips from experts on how to avoid battery problems:
- Keep your battery clean: Corrosion can build up on the battery terminals over time, which can reduce the battery’s performance. To prevent this, keep the battery terminals clean and free of corrosion.

- Don’t run your car’s accessories for extended periods of time: Running your car’s accessories for extended periods of time can also drain the battery. To avoid this, only run your accessories when you need them.
