Car mechanic is using the car battery meter to measure various values and analyze it.

As the days grow shorter and the weather turns colder, it’s essential to make sure your car’s battery is in tip-top shape. Not doing so can have dire consequences.

Summer May Have Damaged Your Battery

The heat of summer can take a toll on your car battery. As the sun beats down, temperatures under the hood can reach up to 170 degrees. Scorching heat increases corrosion inside the battery and shortens its lifespan, causing it to lose its charge.

Cars have a harder time starting in colder temperatures, so it’s important to have your battery tested ASAP. Without a little preventative maintenance, you may wind up stuck with a dead battery at an inconvenient time.

Warning Signs Your Battery is Dying

Ideally, the best time to replace your car’s battery is before it dies. So how can you tell if your battery is nearing the end of its life? Common red flags that it may be reaching the end of its life include:

  • Check engine light is on
  • Engine is slow to start
  • Lights are dim
  • Onboard electrical components are not working as usual (e.g., radio, power windows, heated seats, cell phone charger, etc.)
  • Something smells foul (like rotten eggs) under the hood
  • The battery case is swollen or cracked
  • Your battery is three to five years old

Fall Car Battery Care

If you haven’t already, schedule a car battery inspection. Technicians should perform a complete diagnostic test of your charging system, and check that the battery connections are clean, tight, and free of corrosion.
