Published in Business Articles

We’ve all had that dreaded moment when you try to start your car, and it just won’t go.

Your car battery is something you might not think about much, but you’ll notice a huge drop-off in performance when it starts to die. So, how long does a car battery last on average? How do you make sure it doesn’t die prematurely?

With so many types of batteries out there, you need one that’s going to stand the test of time. In this post, we’re going to look at the lifespan of your car battery and what you can do to ensure that it runs efficiently during that lifespan.

If you’ve had one too many car batteries die on you, keep reading and figure out how to prevent that from happening again.

How Long Does a Car Battery Last on Average?

The average car battery lifespan is between 3 and 5 years. How long your battery lasts will depend heavily on what you do with your car. Some batteries will tell you when they’re about to die, while others will die without warning.

If you’ve had a battery for longer than 5 years, it could die without notice. This is something you have to take into consideration when you’re buying a used vehicle. Should your battery die suddenly, you could end up stranded somewhere inconvenient.

There are alternative car battery options out there. The good people at RB Battery, for instance, are at the forefront of automotive battery technology, offering the best car batteries that last for years longer than traditional lead-acid batteries.

Whatever type of battery you end up with, make sure to start testing it around 3 years.

How They Die

The purpose of a car battery is to deliver enough charge for your starter to start the car. Once it’s running, the car’s alternator will maintain the 12.6 volts needed to power the car’s starter again.

When your battery’s charge starts to diminish, it’s usually due to some of these common occurrences:

  • You’ve left your dome and/or headlights on while the car isn’t running
  • Corroded connections in the battery prevent it from charging while the car is running
  • Extreme heat or extreme cold
  • Other small lights (glove box, trunk, etc.) that slowly drain the battery

Detecting Failing Automotive Batteries

Sometimes your car will give you a sign that your car battery is about to fail. One of the most common is slow starting. If you get clicking or buzzing when you turn on the ignition, this usually indicates an issue with your battery.

Sulfuric acid or egg smells emanating from your battery mean that your battery has some sort of structural problem and should be replaced immediately. You can check the top of the battery for acid leaks or corrosion if this happens.

Replacing a Car Battery Is Part of Car Ownership

If you take care of it, it can last a full lifespan of 5 years. When you invest in a state-of-the-art car battery, it might be far longer. As a car owner, replacing your battery is part of the deal, so make sure to test it when you know it’s old and be ready to buy a new one when it shows signs of wear.
