When car batteries die, there is almost always an underlying issue. While the seriousness of these issues can vary, you should not write your dead battery off as a fluke. A jumpstart might fix the initial problem, but there’s always the chance that whatever went wrong will happen again if you neglect the problem. Check out the list below to learn more about a few of the most common causes of a dead car battery.

5 Common Causes of Dead Car Batteries

1. Lights Left On

Headlights or internal car lights will drain a battery if left on for an extended period. Always check for any interior lights when it's dark out and make a habit of clicking your headlights off every time you exit your vehicle.

2. Extreme Temperatures

While hot or cold weather won't kill a new battery that's in decent shape,  aging car batteries with less stamina could fail under extreme weather conditions. Should this occur, you should address the issue with your mechanic and consider replacing your car’s battery.

3. Old Battery

An old or weak battery won’t hold a full charge. If you notice that your vehicle consistently won't start, the battery may be worn out. An old or poorly maintained array will continue to die regularly, so you should replace your car battery every three to four years.

4. Corroded Connections​

When battery connections become corroded, they prevent the battery from charging correctly. If you notice your battery terminals have minor corrosion, remove them and clean them. You should use a wire brush and a solution of baking soda and water or a can of battery terminal spray cleaner. If the corrosion is more severe, you may need to replace the battery.

5. Faulty Charging

A faulty charging system will drain your car’s battery even while you’re driving. Since many vehicles power their lights, radio, and other systems from the alternator, this will make the battery drain even faster if there's a charging issue. If your vehicle’s alternator has loose belts or worn-out tensioners, consult a mechanic to address these issues.
