How Hot Weather Affects Car Batteries

How Hot Weather Affects Car Batteries

If you live in a warm climate, you’re used to dealing with high temperatures and the effects they can have on your car. This heat can take its toll on your health, your psyche, and of course, your car battery. A typical car battery operates best up to 90 degrees Fahrenheit, so temperatures above that range can mean big problems for your battery.

Battery problems due to heat

Contrary to popular belief, hot weather is even more detrimental to your car than cold weather.  An average car battery can last anywhere from three to seven years, but that lifespan can be significantly less in warm-weather climates.

Here’s why:

  • Excessive heat can actually accelerate the battery’s chemical operation, causing battery fluid to evaporate.
  • Loss of battery fluid can permanently damage the internal structure of the battery.

One way to help keep your battery functioning properly year-round is by keeping it clean. The terminals should be corrosion-free, and of course, be sure to have the battery checked regularly by a professional.

Tips for getting the most out of your car battery

  • Store your car in a garage if possible
  • Avoid charging things like cell phones and GPS devices through your car
  • Keep the battery clean. Excessive dirt can drain battery power
  • Always replace a battery with one that is of equal or higher quality than the one originally specified
  • Be sure your electrical system is charging the battery at the right rate. Undercharging and overcharging can be equally damaging

No matter where you live, what you drive, or how many miles you put on your vehicle, it’s important to feel confident in your car’s battery by getting routine battery checks. If the engine crank is slow, or you hear clicking, you might need a new battery. Learn about your battery options here, or schedule an appointment for a battery check at Sears Auto Center today!
