Keep Your Battery Cool in Summer Heat to Avoid Being Stuck in the Cold

(BPT) - A dead car battery is more likely to leave you stranded in a winter freeze than the summer sun. But keeping your car battery healthy in the warmest months will help you avoid getting stuck when temperatures plunge.

Contrary to popular belief, heat drains car batteries much faster than a blustery cold. Experts at Clarios, the world's largest car battery manufacturer, say that high heat speeds up the chemical reactions inside a battery, which leads to the evaporation of internal fluids and faster corrosion of essential components. Coupled with high temperatures under the hood, batteries can weaken silently during the summer months.

Man in the dessert with the hood popped on his car.

More important than ever

12-volt batteries, found in all types of vehicles from traditional gas-powered cars to full battery electric vehicles, have evolved beyond starting the vehicle to supporting safety critical and convenience features including start-stop and advanced driver assistance systems. The low-voltage battery provides reliable and dependable power, protecting against failures that could put occupants at risk.

Three simple ways to prevent cooking your battery in the sun

Nearly one in four vehicles on the road today needs a new battery - most without warning signs of upcoming failure.

While you're out chasing summertime fun, experts at Clarios, the maker of 1 out of every 3 car batteries on the road today, offer three simple ways to avoid heat-related battery issues:

  1. BE PROACTIVE: If your battery is three years old or more, have it tested before the summer heat sneaks up on you. Many service centers and auto parts retailers offer complimentary battery tests to help drivers avoid the inconvenience - and cost - of a dead battery.
  2. CHOOSE THE RIGHT BATTERY: A battery needs to be built for and tested against extreme heat. AGM (absorbent glass mat) batteries are designed to handle the summer heat. They are also designed to support the electrical demands of today's vehicles including start-stop technology and hybrid/electric vehicles.
  3. PARK IN THE SHADE AND BE PREPARED: Park in the shade when you can, keep your battery terminals clean and know the signs of a weak battery such as slow engine cranking, dim headlights and never ignore an illuminated battery warning light.

With the proper maintenance and choosing the right battery for your vehicle, you can cruise down the sunny highway with peace of mind that when winter comes, your battery will be ready for the coldest days.
