Summer’s here, and with it comes scorching temperatures that can wreak havoc on your vehicle’s battery. But fear not! AAA is here to provide the inside scoop on how to keep your battery health and avoid a roadside meltdown.
How Does Heat Hurt Your Battery?
Chemical Reactions on Fast Forward: Car batteries rely on chemical reactions to function. Hot weather accelerates these reactions, leading to excessive evaporation of the electrolyte (the liquid inside) and damaging the battery’s internal components.
Shorter Battery Life: Think of your battery like a superhero. Extreme heat weakens its superpowers, reducing its ability to hold a charge and cranking power for starting your car.

Combating the Heatwave?
Park Smart: Whenever possible, park your car in a shaded area or garage. This shields the battery from direct sunlight and keeps it cooler
Pop the Hood (After Driving): Letting the engine compartment cool down after a drive helps dissipate heat trapped around the battery. Safety Tip: Only do this once the engine is off.
Keep it Clean: A dirty battery case can trap heat. Regularly clean the battery case with a damp cloth and baking soda solution (always disconnect the battery terminals first)
Test and Consider Replacement: Schedule your complimentary battery test by visiting AAA.com/Battery. If your battery is over 3-4 years old, consider replacing it before 4th of July road trips or before the summer heat intensifies.
Bonus Tip!
During heat waves, avoid overloading your electrical system by limiting non-essential accessory use like air conditioning (when possible) for shorter trips.
By following these simple tips, you can ensure your car battery stays cool, healthy, and ready to keep you on the road all summer long.
Happy Road Tripping!
