The 2017 Jeep Grand Cherokee is a midsize Sport Utility Vehicle (SUV) that is perfect for families. With three rows of seats, ample cargo space, a touchscreen interface, a rearview camera, and a powerful engine, it provides a more pleasurable driving experience.

However, even a high-quality SUV like the Grand Cherokee requires periodic maintenance, such as replacing the auxiliary battery. This article provides a guide to help you locate the auxiliary battery in your Jeep.

Does a 2017 Jeep Grand Cherokee have 2 batteries?

The 2017 Jeep Grand Cherokee has two batteries to power all of its features. The primary battery is responsible for starting the car, while the auxiliary battery powers the SUV’s extra features, such as heated seats, the touchscreen interface, and the rearview camera.

These two batteries are designed to provide the following benefits:

  • The auxiliary battery can power the vehicle’s electrical system when the engine is off, making it useful for starting the engine or running accessories.
  • If one battery fails, the other battery can provide power to the car, ensuring that you are not stranded on the side of the road and can continue your journey.
  • Having two batteries helps the engine run more efficiently, allowing the alternator to work less, which in turn means that the engine can run cooler, last longer, and improve fuel economy.
  • The two batteries give you more storage capacity and 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, to maintain a smoothly working engine and avoid complications in the future, it’s important to perform routine service checks on your vehicle. This practice can help prevent potential issues before they occur.

Another important aspect to consider is knowing the battery location of your vehicle. By knowing where the batteries are located, you can save time, money and prevent any surprises when problems arise.
