What is the Lifespan of a Car Battery?

If you’re tired of looking for the jumper cables every time you want to start your car, you may be wondering what is the lifespan of a car battery. A dead battery is a frustrating inconvenience that can be avoided if you know the signs of a dying battery. The fear of being stranded in a parking lot or on the side of the road is a constant concern for drivers.

But how do you know what is the lifespan of a car battery? There are some obvious signs that your battery is starting to fail, such as:

  • Slow engine crank
  • Illuminated check engine light
  • A swollen, misshaped battery case
  • Battery fluid leak

So what is the lifespan of a car battery? Generally, a battery will last anywhere between three to five years before starting to fail. However, you may be looking at a car battery replacement before three years depending on the climate where you live and your driving habits.

  • The Effect of Climate: Summer’s heat can lead to the evaporation of water in the battery acid, resulting in decreased performance, subpar starting power, and a shortened lifespan. When temperatures are freezing, your battery has to work harder to generate the energy to keep your car running smoothly. Cold temperatures also cause engine oil to thicken, putting an additional strain on your battery.
  • The Effect of Driving Habits: Consistently taking short trips, such as commutes to the office, school, and grocery store, your battery doesn’t have enough running time to recharge fully between stops. Also, if you let your car sit in the garage or driveway for long periods of time, even with the engine off, there is a massive draw on the battery.

A general rule of thumb is that you should replace your car battery about every three years even before you see signs of failing. A simple word of advice–be proactive and replace your car battery before it dies.
