by Phil Borges // in Car

The 2017 Jeep Grand Cherokee is a midsize Sport Utility Vehicle (SUV) ideal for families. It features three rows of seating, vast cargo space, a touchscreen interface, a rearview camera, and a powerful engine, making it a more pleasurable experience.

Nevertheless, even a high-quality SUV needs periodic maintenance, including replacing the auxiliary battery. This article will guide you through finding your Jeep’s auxiliary battery.

Does a 2017 Jeep Grand Cherokee have 2 batteries?

The 2017 Jeep Grand Cherokee has two batteries to power up all its beautiful features. The first battery is the primary battery, which is responsible for cranking the engine and starting the car. Meanwhile, the auxiliary battery is the second battery that provides power to all of the SUV’s extra features, like the heated seats, touchscreen interface, and rearview camera. 

These two batteries are carefully designed to meet the following benefits:

First, the extra battery can power the vehicle’s electrical system when the engine is turned off, which can come in handy if you’re trying to start the engine or run some accessories.

Second, if one of them fails, the other battery can still provide power to the car. This means you won’t get stranded on the side of the road, and you can continue your journey with ease.

Third, having two batteries help your engine run more efficiently. When you have two batteries, it allows your alternator to work less, which means that your engine can run cooler and last longer. Having two batteries also helps to improve your fuel economy.

Lastly, these two batteries give you more storage capacity and can help you stay powered up even when driving in extreme conditions.

Where is the auxiliary battery in Jeep Grand Cherokee?

The auxiliary battery’s location varies depending on the model of Grand Cherokee. However, for the 2017 Jeep Grand Cherokee, both primary and auxiliary batteries are located under the passenger seat, which is different from the specific location of batteries in most cars in the engine compartment.

Here are simple guidelines to access these batteries in your Jeep Grand Cherokee:

  • Ensure that the Grand Cherokee is turned off before you start working.
  • Lift or push forward the seat. The storage compartment on the floor of the vehicle houses both batteries.
  • A plastic battery cover covers the compartment. Remove the cover to access both batteries.
  • Both batteries are secured in place by two Phillips head screws. Remove these screws to access the batteries.
  • When working with batteries, ensure to handle each battery with caution as they contain acid that can cause injury.

The 2017 jeep grand Cherokee battery location is not hard to find. It is a good idea to check the battery regularly to make sure it is in good condition and has enough water.

Do Jeep Grand Cherokee use AGM batteries?

The AGM battery is one of the different types of batteries used in the Jeep Grand Cherokee. It is often used due to its advantages, namely:

  • It doesn’t suffer from the “memory effect” that can plague other types of batteries. It means you won’t have to discharge and recharge it to maintain peak performance.
  • It is less likely to explode or leak than other batteries.
  • AGM batteries are sealed and don’t require maintenance, making them an excellent option for those who don’t want to worry about topping off their battery or checking the water level.
  • It is resistant to vibration and shock, making them a good choice for vehicles that are often driven on rough terrain.

How can I tell if my Jeep Grand Cherokee battery is bad?

The best way to test if your Jeep Grand Cherokee battery is bad is to take it for a drive. If the car does not seem to be accelerating or braking as smoothly, this could be an indication that the battery needs to be replaced.

Another sign of a weak battery is when the engine turns over slowly. You can also try testing the battery voltage with a multimeter. A healthy battery should read at least 12 volts. The battery may need to be replaced If it reads lower than this.

You can check the Jeep Grand Cherokee’s charging system by observing the indicator light on the dashboard. If this light is illuminated, there is a problem with the charging system, and the battery should be tested.

Sometimes you could hear some strange noises coming from the engine bay. This could also be a sign of an issue with the battery.

Issues with specific components in the electrical system, such as the alternator or starter, can also lead to a bad battery.

If you are experiencing any of these problems, it’s best to have the battery checked by a professional. They will be able to test the battery and determine if it needs to be replaced.


In conclusion, the best way to avoid complications down the road is to perform routine service checks to maintain your engine working smoothly. This will help you avoid any potential issues in the future. In addition, knowing where the batteries are located in your vehicle will save you both time and money and prevent any surprises along the way when problems occur.
