Keep your car battery cool in the heat

FEBRUARY 11, 2016

Whether you’re out on the open road or just at home, your car battery can take a beating during the summer months. Contrary to popular belief, skyrocketing temperatures pose a greater threat to your car battery than winter chills. Here’s why.

Heating up

Excessive heat can cause battery fluid to evaporate which can damage the internal battery structure. High temperatures, combined with heavy traffic on overheated tar roads, can hike up the temperature under the hood of your car and push your car battery to its limits.

Batteries are prone to faults during hot weather, that worsen gradually and are often only noticed once cooler temperatures set in. It’s therefore vital to maintain your vehicle battery throughout the year, but particularly during warm weather.

Basic maintenance tips

  • Check terminal conditions under the hood regularly
  • Check radiator fluid levels to avoid overheating
  • Ensure battery connections are clean and tight – no dirt, engine grease or corrosion (often looks blue)
  • For older batteries, refill with distilled water, if necessary
  • Wherever possible, park your car in shady spots or a garage
