In this article, we’ll take a closer look at why the battery light is so important, the possible causes of the problem, and what you should do when your car’s battery light comes on and your car stops running.
Understanding the warning signs
Battery light comes on
When the battery light comes on, it’s a clear indication that something is wrong with your car’s charging system. This light can be solid or flashing, and can vary in color. The most common color is red, which indicates a serious problem and that the charging system is not functioning properly.
A few things that can cause the battery light to come on are a faulty alternator, corroded or loose battery cables, a bad battery, or a blown alternator fuse. It’s important to have your car inspected by a mechanic if this warning sign appears.
If your car dies, it’s likely that the battery is not being charged properly. This can be caused by a variety of issues, including a dead battery, faulty alternator, or bad starter. If your car dies while driving, it can be a dangerous situation and could result in an accident. If this warning sign appears, it’s important to pull over safely and seek assistance immediately.
Regular maintenance can help prevent these warning signs from occurring. It’s important to have your car’s charging system inspected regularly, and to replace the battery and alternator as necessary. Don’t ignore these warning signs, as they can leave you stranded on the side of the road or result in costly repairs.
Common causes of battery failure
A common reason for battery failure is simply that the battery has reached the end of its life. Typically, a car battery lasts between three and five years, but this can vary depending on usage, climate, and other factors. Over time, the battery’s capacity to hold a charge will decrease until it is no longer capable of powering the car’s electrical system.
Excessive Heat or Cold
Extreme temperatures can also cause battery failure. High temperatures can cause battery fluid to evaporate, which can damage the internal components of the battery. Cold temperatures can reduce a battery’s ability to produce the electrical energy needed to start the car. This is why many car batteries fail during the winter months in colder climates.
If the car’s electrical system is left on when the engine is not running, such as leaving the headlights, radio, or other accessories on overnight, it can drain the battery. While most cars have systems in place to prevent this, such as automatic shut-off, these systems are not foolproof and can be overridden by user error. It’s important to be mindful of your car’s electrical usage and to turn off any accessories when the engine is not running.
Faulty Charging System
The charging system in a car is responsible for keeping the battery charged while the car is running. If the charging system is faulty, the battery may not receive the charge it needs to operate. This can happen if the alternator, voltage regulator, or other components of the charging system fail or malfunction. If the battery light on your car’s dashboard comes on, it may indicate a problem with your charging system.
Corrosion on the battery terminals and cables can cause poor electrical connections, which can affect the battery’s ability to charge and discharge properly. It’s important to keep the battery terminals and cables clean and free of corrosion to ensure proper operation.
While there are many potential causes for battery failure, proper maintenance and attention can help prevent most issues. Regularly inspect your battery and charging system for signs of wear or damage, and take steps to keep your car’s electrical system in good working order.
Steps to take when the battery light comes on
1. Check your dashboard and electrical system
When your battery light comes on, it’s important to quickly assess the situation. Check your dashboard for any other warning lights or indicators that may provide some insight into the problem. Additionally, try turning off any non-essential electrical systems, such as the radio or AC, to lighten the load on your battery.
2. Pull over and turn off your engine
If you’re driving when the battery light comes on, pull over to a safe location as soon as possible. Turning off your engine will help lessen the load on your battery and prevent any possible damage to the electrical system.
3. Inspect your battery and connections
If possible, open the hood and visually inspect your battery and its connections. Look for any signs of corrosion, loose wires or cables, or visual damage to the battery itself. Clean any corrosion with a wire brush and tighten any loose connections.
4. Call for assistance if needed
If you’re unable to determine the problem or fix it yourself, it’s best to call for assistance from a roadside service or a mechanic. They can provide more insight into the problem and help get your car up and running again safely.
5. Avoid using non-essential electrical systems
Once you’ve resumed driving, try to avoid using any non-essential electrical systems until you’re sure the problem has been resolved. This will help lessen the load on your battery and prevent any further issues.
How to Prevent Battery Failure
1. Regular Maintenance
Regular maintenance is one of the most important aspects of preventing battery failure. Be sure to check your car’s battery and electrical system regularly, especially before long trips or during extreme weather conditions. Ensure the battery and cables are clean and free of corrosion. Also, check the electrolyte level in the battery regularly and top up with distilled water as needed.
2. Keep Your Car in a Garage
If possible, park your car in a garage or under a carport to protect the battery from extreme temperatures. Batteries can fail in extreme heat or cold, so a garage will help to keep the battery within the ideal temperature range.
3. Turn Off All Electronics When Not in Use
When you are not driving your car, make sure to turn off all electronics, such as the radio and air conditioning, to avoid draining the battery unnecessarily. Also, turn off the headlights and interior lights when you get out of the car, as these can also drain the battery quickly.
4. Drive Your Car Regularly
If you don’t drive your car frequently, the battery can become discharged and eventually fail. Make sure to drive your car regularly, at least once a week, to keep the battery charged and prevent it from failing.
5. Invest in Quality Parts
To prevent battery failure, invest in quality parts when replacing your car’s battery or any other electrical component. Cheap, low-quality parts may cause electrical issues and eventually lead to battery failure.
6. Check Your Alternator
Your car’s alternator is responsible for recharging the battery while you drive. Make sure to have it checked regularly to ensure it is functioning properly. A malfunctioning alternator can cause the battery to drain and eventually fail.
7. Keep Your Battery Charged
If you have an older car or a car that you don’t drive frequently, consider investing in a battery maintainer or trickle charger. These devices will keep your battery charged and prevent it from becoming discharged and failing.
8. Replace Your Battery When Needed
If your battery is old or showing signs of wear, it may be time to replace it. Don’t wait until it fails completely to replace it, as a dead battery can leave you stranded.
9. Follow Your Car Manufacturer’s Recommendations
Follow the maintenance schedule recommended by your car manufacturer to ensure your car’s battery and electrical system are in good condition. This will keep your battery functioning correctly and help prevent battery failure.

What to do if the car still dies after replacing the battery
Check the Alternator
Replacing the battery is only a temporary solution. If your car dies again after replacing the battery, then you should check the alternator. The alternator is responsible for charging the battery while the car is running, and if it’s not functioning properly, then the battery will eventually die again.
You can test the alternator by using a multimeter. Connect the multimeter to the battery while the car is running. If the alternator is working correctly, you should see a voltage reading between 13.5 and 14.5 volts. If the reading is lower than that, then the alternator needs to be replaced.
Check the Starter Motor
If the alternator is working correctly, then you should check the starter motor next. The starter motor is responsible for starting the engine, and if it’s malfunctioning, then the car won’t start no matter how much power is left in the battery.
You can test the starter motor by turning on the headlights and trying to start the car at the same time. If the headlights dim when you turn the key, then the starter motor is drawing power from the battery, but it’s not working properly. In that case, the starter motor needs to be replaced.
Check for Corroded Cables
If both the alternator and the starter motor are working correctly, then you should check the cables connecting the battery to the rest of the car. Corroded or damaged cables can prevent the battery from charging or delivering power to the car.
Inspect the cables for any signs of damage or corrosion. If you find any damage, replace the cables immediately. You can also clean corroded cables with a wire brush and a mixture of baking soda and water.
If your car is still dying after replacing the battery, don’t panic. Check the alternator, starter motor, and cables to determine the root cause of the problem. If you’re not comfortable working on your car, take it to a mechanic to get it diagnosed and repaired.
