  • An illuminated Check Battery light on your dashboard
  • Battery fluid leaks
  • Low battery fluid levels
  • Slow engine turnover or sluggish starting
  • Swelling battery case

How Often to Replace a Car Battery

Several factors influence how often you should replace your car battery. Factors like frequent short drives, extreme temperatures, and your regular driving routine can impact your battery’s lifespan. Generally, service technicians recommend replacing a car battery every four to five years.

What Causes Car Battery Deterioration?

So what causes your car battery to deteriorate? Car battery deterioration can occur due to various factors, impacting its overall performance and lifespan. One primary cause is frequent short drives, as these prevent the battery from fully charging, leading to a gradual loss of capacity. Extreme temperatures, both hot and cold, also play a significant role, affecting the chemical reactions within the battery and accelerating its deterioration.

Additionally, overcharging or undercharging, often caused by faulty alternators or voltage regulators, can contribute to the breakdown of a car battery over time. Corrosion on battery terminals, inadequate maintenance, and a high number of discharge cycles further contribute to the wear and tear, emphasizing the importance of regular checks and proper care to extend the life of a car battery.

How to Get the Most Out of a Car Battery

Now that you know when and how often to replace a car battery, take steps to maximize its lifespan:

  • Check battery voltage monthly, making sure it’s about 12.7 volts or higher
  • Confirm the battery is tightly fastened in its compartment.
  • Don’t let your car sit undriven for extended periods.
  • Limit the number of short trips you make.
  • Remove any corrosion on the outside of the battery with an old toothbrush and a paste of baking soda and water.
  • Park in shaded, cool areas to prevent the battery from overheating.
  • When the engine is off, don’t use the headlights or interior lights, or keep their use to an absolute minimum.

How to Test a Car Battery

Have your car battery tested as part of routine maintenance at your service center in the Fort Wainwright area twice a year. If you wish to conduct additional tests between these scheduled appointments, many retailers provide free testing services. Alternatively, you can perform battery tests at home using a few straightforward methods.

The Headlight Test: 

  1. Turn on the engine, keep the car in park, and make sure the headlights are on.
  2. Rev the engine and see if the headlight brightness changes.
  3. If the headlights get brighter, that means the current is not strong enough to keep the lights at normal brightness while the car is idling.
  4. Take your car to a service center at this point for further assessment.

Using a Digital Multimeter:

  1. Set the voltmeter to 20 DC volts.
  2. Under the hood, touch the negative terminal (black) with the negative meter probe (also black).
  3. Touch the positive terminal (red) with the positive meter probe (also red)
  4. Have a friend turn on the headlights and check the voltmeter reading.
  5. At 80℉, 12.5 volts or higher means your battery is fully charged. 12.3 volts means it’s at about 75% charged.11.8 volts or lower means you have 25% or less charge.
