...Extreme heat weather can actually kill more vehicle batteries than cold winter weather? Most drivers know that the cold is rough on car batteries, but heat is actually the number one cause of battery failure and reduced battery life. Extreme heat accelerates the rate of fluid loss and the resulting oxidation of battery components, which can leave you stranded without warning.

Here are a few quick tips on how to avoid that moment when you turn the key in the ignition and nothing happens.


  1. Your car doesn't start immediately or makes a clicking noise when you turn the key.
  2. Your headlights or interior lights are dimmer than normal, or the power windows are working slower than usual.
  3. You see stains or signs of corrosion on the battery itself.
  4. Your battery is more than three years old.
  5. You take a lot of short trips where the car is turned on and off often, or you have long stretches of time (weeks or months) where the car is not used at all.


  1. Turn off your lights, wipers, and A/C before you turn off your engine at the end of a drive to prevent an unnecessary drain on the battery the next time you start your car.
  2. Unplug phone chargers and USB cables for devices as soon as you turn off your engine (for the same reason as #1).
  3. Avoid using your car's A/C longer than you have to, as the A/C system puts high demands on your battery.
  4. If you see corrosion on your battery, clean it or have it cleaned by a trained technician.
  5. If you consistently go two weeks or longer without using your car, invest in a battery tender to keep the battery charged.
