Car battery dies when trying to turn on

One of the most frustrating experiences a driver can have is turning the key in the ignition, only to have the car battery die. It can be even more frustrating when the car battery dies repeatedly when trying to turn on the vehicle. This can happen for a variety of reasons, ranging from simple to complex issues.

One of the most common causes of a car battery dying when trying to turn on is a dead or weak battery. If the battery is old and has not been replaced in a while, it may not hold a charge well, causing it to die when a large amount of power is needed to start the car. Alternatively, if the battery has been drained several times, it may have sustained damage that prevents it from holding a charge.

Another potential cause of a car battery dying when trying to turn on is a faulty alternator. The alternator plays a crucial role in charging the battery, and if it is not functioning properly, the battery will not be able to hold a charge or maintain enough power to start the car. Additionally, corroded or loose battery cables can cause similar issues, as they can hinder the flow of power from the battery to the starter.

In this article, we will explore the common causes of a car battery dying when trying to turn on and provide solutions on how to fix the issues. By understanding the underlying causes of the problem, drivers can take proactive steps to ensure their cars start correctly and reliably every time.

Car Battery Dies: Common Causes and Solutions

1. Old Batteries

One of the most common causes of car battery death is an old battery. Batteries usually last between three and five years, but this can vary depending on usage and climate. If your battery is older than five years, it’s time to consider replacing it.

Corroded battery terminals can also cause your car battery to die. Check your battery terminals for white or green buildup and clean them with a wire brush and baking soda solution. It’s important to also check the cables connecting the battery to the car’s engine. If they’re corroded, they may also need to be replaced.

3. Parasitic Drain

If your car’s battery dies frequently, even when the car is not being used, it may be experiencing a parasitic drain. This occurs when there is an electrical component in the car that is drawing power from the battery even when the car is turned off. This can be caused by a faulty alternator, a malfunctioning electrical component, or a battery that’s not charging properly.

4. Extreme Temperatures

Extreme temperatures can also cause car batteries to die. This is because high temperatures can cause the battery fluid to evaporate, while low temperatures can make it harder for the battery to produce enough power to start the engine. Park your car in a shaded area or garage during extreme temperatures to prolong your battery’s life.

5. Overuse

Overuse of the battery can also cause it to die prematurely. This includes leaving the lights on or listening to the radio while the engine is off. Avoid doing this and give your battery time to recharge by taking longer drives or using a battery charger.


Keeping your car battery in good condition is essential for ensuring that your car starts every time you need it. Regular maintenance, such as cleaning the terminals and checking the charging system, can help prolong the life of your battery and prevent unexpected breakdowns.

  • Replace old batteries
  • Clean corroded terminals
  • Check for parasitic drain
  • Protect from extreme temperatures
  • Avoid overuse
