How Often to Replace a Car Battery

Some experts suggest that drivers replace their batteries about every 4-5 years; however, these numbers will vary depending on several factors. If you want a better idea of when your battery needs to be replaced, read this guide by the service experts at Hudson Nissan. We’ll go over how to know if your car battery needs to be replaced, how to test a car battery, and more! 

How to Know If Your Car Battery Needs to Be Replaced

How do you know if your car battery needs to be replaced? There are some warning signs that you can look out for that will let you know if your battery is nearing its end:

• You notice that your headlights are dimming
• The vehicle needs engine revving or jump starts more frequently 
• The engine takes longer to start when you turn the key/push the button
• There are fluctuations in power 

What Factors Impact a Battery’s Lifespan?

As you’re driving throughout Newark and Bayonne, your battery is naturally going to deteriorate over time. Here are some of the factors that cause your battery to deteriorate:

• Hot weather: Heat evaporates liquids inside of a car battery. As a result, if you live in a hot climate, your battery life will be shorter. 
• Vibrations: If you frequently drive over rough roads or your battery’s hold-down clamps are loose, the vibrations will gradually break down the battery’s internal components. 
• Jump Starts: Have you ever let your lights on overnight or let your engine idle for too long so that it required a jump start? If so, this can significantly drain your battery. 
• Time: A car battery can only go through a certain number of charge cycles until it inevitably dies. However, proper care can help prevent your battery from dying early.

If you’d like a better idea of how long your car battery should last when well-maintained, read your owner’s manual or schedule a service appointment at Hudson Nissan to speak with a technician.

How to Test a Car Battery

It’s recommended that you have your battery tested during your vehicle’s regular maintenance appointment at your Hillside area service center about twice a year. Although, if you want to test your battery between service appointments, many retailers will conduct a test for free — or, you can test the battery at home using one of the following 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, it means that 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 about 75% charged.11.8 volts or lower means you have 25% or less charge. 

How Much is a Replacement Car Battery? 

The typical car battery cost can range between $75 and $120, and if you have a premium battery, as much as $200. If you drive a hybrid vehicle, because they have much larger batteries, replacements are more expensive and can cost anywhere from $1000 and $6000.
