How Long Do Jeep Batteries Last?

Under the hood of your Jeep, there’s an SLI battery that stands for starting, lighting, and ignition. This battery provides electric power to start the engine and power the other systems in the vehicle, such as lights and accessories. It’s an essential part of your Jeep because the vehicle won’t run without it. But how long does it last, and when should you replace it? Read this guide for a full understanding of your Jeep’s battery and what you can do to extend its life span, then schedule a service with us today!

How Long Does a Jeep Battery Last?

On average, a Jeep battery lasts between three and five years. For many people, this means they’ll need to replace the battery at some point during their Jeep ownership. The life span of a Jeep battery can vary based on different factors, including:


Heat can cause a battery to degrade faster. If you park your Jeep outdoors during the hot summers in Angleton, Texas, you may find yourself replacing the battery sooner than your cousin who lives in Minnesota. According to AAA, it’s typical for car owners in hot Southern locations to replace their batteries around three years, whereas people in colder Northern climates may get five years out of their batteries.

Driving Habits

How you drive your Jeep can also affect the battery life. If you take your Jeep off-roading on the trails frequently, you might need to replace the battery more quickly. The vibrations from tackling uneven or rough terrain can lead to vibrations, causing the battery’s internal parts to break down over time.

Typical Use

You probably know that if you don’t drive your Jeep for an extended period, the battery will likely die. But if you mainly use your Jeep for short trips, such as running errands or going to the gym, it may also cause the battery to deteriorate more quickly. That’s because short trips don’t allow enough time for the battery to charge fully.

Signs That It’s Time for a New Jeep Battery

If you’ve ever left the lights on overnight, you may know the sinking feeling that comes when you get behind the wheel and the vehicle won’t start. Aside from a completely dead battery, there are warning signs that can tell you when it might be time for a new battery. Here are some signs of a weak battery:

  • The engine is slow to start. When you start the Jeep and it takes longer than normal, that’s a sign the battery may be nearing the end of its life.
  • Electrical systems seem weak. If your phone charges very slowly or the windows take an extra few seconds to roll down, it might signal a weak battery.
  • You notice leaks or corrosion. If you notice fluid leaks or a buildup of corrosion near the battery, it may be time to replace it. However, minor corrosion isn’t a cause for concern because it can be cleaned.
  • The check engine light appears. While the check engine light can indicate various potential problems, it can sometimes be related to a weak battery. Take your Jeep to a dealership or service center to determine what’s causing the light to appear.

How Often Should You Replace a Jeep Battery?

Typically, you should replace a Jeep battery every three to five years. Make sure you’re testing the battery every time you take it in for maintenance. Jeep dealerships will usually check the battery as part of a multi-point inspection when you bring in your vehicle for an oil change or tire rotation. After three years, make sure you test your Jeep’s battery annually so you don’t find yourself stranded on the side of the road.

Can You Drive a Jeep After the Battery Light Comes On?

If your battery light comes on while driving, it usually means the alternator isn’t charging the battery correctly. In other words, the Jeep is only running on battery power and will drain quickly. When this happens, turn off other electrical systems, like the air conditioning and radio. You may be able to drive your Jeep home or to a repair shop if it’s nearby. If you’re far from home, find a safe place to pull over and call for help.

Tips To Extend the Life of a Jeep Battery

Even though the Texas heat may not do your Jeep battery any favors, there are some ways you can extend its life span. Here are some tips to extend the life of your battery:

  • Make longer trips. If possible, make longer trips to give the battery time to charge fully. Combine your errands or take your Jeep on road trips outside the city.
  • Always check your lights. Whenever you exit your Jeep, make sure you close the doors completely and turn off the headlights if they’re not automatic. Find a way to make yourself remember to check the lights, whether it’s using a sticky note or adding a reminder in your phone.
  • Limit electronics when the vehicle’s not running. Whenever you’re parked with the engine off, limit the use of other electronics, such as the radio and air conditioner.
  • Park in the garage. Parking your Jeep in a garage, especially in the summer, can prevent the battery fluid from evaporating.
  • Start your Jeep often. If you don’t drive your Jeep every day, make sure you start it often so the battery can charge.
  • Test the battery. You can use a battery tester to check your Jeep’s battery. By testing the battery consistently, you can know when it’s time for a new one before it dies completely.
  • Schedule battery service. Routine battery service, like inspections and terminal cleanings, can keep your battery running longer. It’s especially important to take your Jeep in for battery inspections if you go off-roading regularly so you can make sure it’s fastened tightly.
