Do Hot Temperatures Kill Car Batteries? 

fixing car battery

 

Sometimes cars refuse to start and the first thing we blame is our car’s battery. Batteries are essential to vehicles as they help start the vehicle and help operate it smoothly. We all know cold weather can drain/kill the battery, but what about heat? Heat is actually worse for car batteries than the cold is! In colder weather, car batteries are said to live around 51 months but in hot weather, they are only predicted to live 30 months. 

How Does Heat Effect Car Batteries?

Extreme heat has been found to cut the lifespan of car batteries. This is because hot temperatures cause the fluids in the battery to reduce faster which damages the battery’s internal structure, weakening its charge. Hot temperatures also lead to the car’s charging system to work differently which often overcharges the battery.

Signs your car battery is dying

The first and easiest way to tell if your car’s battery is dying is when the car has trouble starting. If the battery light turns on and you feel that the engine is a little harder to start, the battery most likely needs to be looked at.

A few other signs of your car battery dying include low fluid levels, dim headlight or interior lights,  swollen battery case, and if the battery is more than 3 years old. If you see any of these signs have the battery charged or replaced as soon as possible.

Can you prevent your battery from dying due to heat?

While it is impossible to control the hot temperatures, here are a few things you can do to make sure the heat doesn’t kill your car’s battery. 

  • Park your car in the shade or in a garage to keep it out of the sun. 
  • Longer drives give the battery more time to recharge. Avoid short drives as often as possible since they don’t give the battery much time to recharge. 
  • Make sure all the lights in and outside your car are off when you park the car. 
  • Clean the battery regularly with a cloth or paper towel. If the battery has too much dirt or grease on it can cause the battery to drain. 
  • Get the battery inspected regularly to ensure that it is working correctly.
