How Often to Replace a Car Battery

Auto Mechanic Replacing Car Battery

Do you know how often to replace a car battery? On average, you should replace your car battery every 4-5 years, however, a few different factors can affect this lifespan. Let’s take a closer look at how to know if your car battery needs to be replaced with Beach Ford! For more information, feel free to contact us anytime!

How to Know If Your Car Battery Needs to Be Replaced

There are some signs to be aware of that could tell you if it’s time to replace your battery:

  • Dimming headlights
  • Engine revving becomes more frequent or you need a jumpstart often
  • Takes longer for the vehicle to start up.
  • Unusual power fluctuations

What Causes Car Battery Deterioration?

  • Heat: The heat can cause the liquids inside the battery to evaporate. If you live in a climate that always has hot weather, your battery life will be much shorter. 
  • Vibrations: If the hold-down clamps on the battery become loose, or you drive on rough roads, these vibrations could cause damage to the fragile components inside the battery. 
  • Needing a Jump: If you often need to jumpstart your vehicle in cases where you’ve left your lights on, frequent jumpstarts could shorten battery life. 
  • Time: Car batteries are only able to cycle through so many charges, and the battery will eventually need to be replaced. However, caring for your battery properly could still extend the life of your battery. 

We recommend checking with your owner’s manual to decide how often your battery should be replaced, as noted by the manufacturer.

How to Test a Car Battery

Now that you know how often to replace a car battery, you may now want to know how to test a car battery. Testing a car battery around Murrells Inlet is quite easy, and can be done in these simple steps:

The Headlight Test: 

  1. Turn the car on, place the car in park, and turn on the headlights. 
  2. See if the brightness of the headlights changes as you rev the engine.
  3. If you notice that headlights getting brighter, this is a sign that the current in the electrical system is not strong enough to keep the lights steady while idling. 
  4. We recommend taking your vehicle to the Beach Ford service center to take care of this issue as soon as possible.

Using a Digital Multimeter:

  1. Set the voltmeter to 20 DC volts.
  2. Touch the negative terminal (black) with the negative meter probe (also black) under the hood..
  3. Touch the positive terminal (red) with the positive meter probe (also red)
  4. Get an assistant to help you, and ask them to turn on the headlights and check the voltmeter reading.
  5. If the multimeter reads 80℉, 12.5 volts or higher, the 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. 

How Much is a Replacement Car Battery? 

So, how much is a replacement car battery in Myrtle Beach? The average car battery can cost anywhere from $75 to $120, however, if you purchase a more expensive battery, it could cost up to $200. If you drive a hybrid, your battery could cost anywhere from $1,000 to $6,000, as it helps to propel the vehicle down the road.
