Why Heat Drains Car Batteries

Heat is a natural byproduct of car use. Whether it's the hot engine, or the sun bearing down on your windshield, you'll probably notice that when you're driving in warm weather, your battery doesn't seem to last as long. This blog post will explain why heat drains car batteries and avoid this problem!

If you've ever wondered why heat drains car batteries, the answer is simple. When your car battery produces electricity, it gives off a chemical reaction that generates heat. This causes more strain on the battery and reduces its effectiveness over time.

When it is scorching, your car battery can get really hot. This can make the battery die. So when the weather is terrible, you need to be extra careful about your car's battery. You want to keep it cool and turn off anything that might make the car hotter (lights, air conditioning).

How Does Summer Heat Damage Your Battery?

In summer, you feel hotter. All of a sudden, you want to drink water after one block! You need water for your car battery too. The liquids evaporate when it is hot, and the battery's charge gets weaker.

When it's hot outside, the corrosion process speeds up, and this can ruin the inside of your battery. It is even worse when you have a dry battery.

Most car batteries are sealed and don't need to be taken care of. But you can tell if it needs water by looking through a window or checking the level.

When winter comes, the temperature can get cold enough to make starting a car difficult. Cold kills batteries. A heat-damaged battery will die even sooner.

The lesson? Yes, heat can deplete automobile batteries!

To Keep Your Battery in the Heat-Resistant Form, You Must:

You probably have extremely hot or cold days no matter where you live. Even if it is sunny in California or Florida, the temperature can change significantly. These tips will help your car's battery stay strong.

  • You should not make short car trips because your battery will not have time to fully recharge. This causes your battery to wear out sooner.
  • Ensure that you turn off all of the lights when you are done using the car.
  • The higher the temperature, the more frequent you will need to charge the battery. If you don't drive often, this will be a problem.
  • Batteries need to be cleaned, so they work better. Dirt can conduct electricity, which means it will drain your battery.
  • Don't use the radio, lights, or other electronics when the car is not on
  • If you park in the sun, your car will get hotter. Park in the shade or garage to keep it cool.
  • Most batteries have a shield. If the shield is not there, the battery will get too hot.

Look For Signs That Your Battery Is Dying.

You can tell if you need your battery looked at by looking for these signs. Some of them are easy to see, like the battery is dead, but others may need a test.

  • Your car doesn't start when you usually do.
  • The check engine light is on the dashboard. It could be because of a problem with your car's engine or battery.
  • When you look at your battery, you see that there is not enough water.
  • The battery case looks like it has air inside or is bloated.
  • There's corrosion present.
  • Your headlights or interior lights are not strong enough.
  • Your battery is older than 3 years.

Sometimes your car battery will go dead, and it can happen when you need to start your car. This is usually because the battery does not have any more juice. If this happens, try to find a new car battery for your vehicle as soon as possible!
