Does hot weather drain your car battery?

Can hot weather drain your car battery? Our resident auto experts have the answers.

Heat warning

Think winter’s chilly temperatures are the only thing to worry about when it comes to your car’s battery health? Think again. The late summer’s sizzling heat can be just as damaging.

That’s because higher temperatures have a greater impact on the power-generating chemistry inside the battery.

Hot weather can increase heat under the hood and accelerate battery failure. When temperatures rise, the battery fluid inside can evaporate, damaging the internal structure.

Here's how it happens

A vehicle battery is much like any other household battery, otherwise known as battery acid. Together, they spark the chemical reaction that powers your ride.

But as the mercury rises, the chemical reaction inside the battery speeds up and can evaporate the battery fluid, causing corrosion. Damaged cells mean a battery produces less and less voltage and can eventually die.

It's important to be proactive about servicing and replacing a car's battery to avoid being stranded. Typically, batteries last three to five years.

While your car's battery can't last forever, here are three easy tips to prolong its lifespan.

Avoid parking in direct sunlight

Keep the sun's heat off your car. Try to park in the shade or, better yet, a covered carport or garage.

Keep your battery clean

Dirt acts as a conductor, and corrosion acts as an insulator, which can interfere with terminal connections and the vehicle's ability to start (and keep running!).

Get regular maintenance

A trained technician can spot issues before they arise. Avoid a battery meltdown with regular maintenance.
