How the summer heat can harm your car battery

SHERMAN, Texas (KXII) - The blazing heat isn’t just dangerous for people and pets, it can also destroy your car’s battery, and leave you stranded.

“We see a big increase in calls for road side service during the summer here at AAA because of the heat. Heat and vibration are a battery’s worst enemy,” said Daniel Armbruster, AAA Texas spokesperson.

And it gets worse the older your battery gets.

“The chemicals inside the car battery are impacted by the heat, makes it harder for that battery to turn over. Especially if your battery is over three years old before you take a road trip,” Armbruster said.

AAA said the average battery lasts three to five years — plenty of time to schedule a checkup before your next road trip.

“Belts and hoses can be warped over time by exposure to the summers that we have here,” said Armbruster “Make sure there’s no wear and tear on them. Also check your fluid levels, sometimes the heat can cause evaporation or other issues.”

Your car needs the same things you do in this heat. A clean air filter to breathe. Antifreeze to cool down., and a radiator — its own personal fan.

“One of the top roadside emergencies we see this time of year is overheated vehicles. That can be for several reasons,” Armbruster said.

So know the warning signs before you’re stranded.

“If your vehicle is having a hard time turning over, if your lights are flickering or faded, take those warning signs serious,” Armbruster said.

Test your battery every six months. Triple A has approved auto repair centers if something seems off — because in this heat, a breakdown means sitting in a sweltering car or walking for help in dangerous temperatures.
