How often should I change the car battery?

When should I replace my car battery? I am experiencing power fluctuation with my vehicle, and I don’t know what to do. Is this a sign I should replace my battery or is there something else wrong with my car?

Great question! On average, it is recommended to change the car battery every four to five years. However, how often you replace your battery depends on a number of factors:
  • Weather: If you live in a hot or cold area, both temperatures can drain your battery and reduce its lifespan.
  • Need frequent jump starts: Every time you jumpstart your car, you are reducing the battery life.
  • Vibrations: Loose battery clamps can cause the internal pieces of the battery to vibrate, which can cause the battery to break down more quickly.
Clear signs that indicate it’s time for a battery replacement:
  • Requiring frequent jump starts
  • Headlights have dimmed
  • Intermittent power loss
  • There is an issue starting the engine or the engine takes a long time to turn over
Make an appointment to see a professional and let them replace your car battery. They can also assess if there are other issues with your vehicle and why the engine is not working properly.
