The Jeep Grand Cherokee has been a favorite among SUV enthusiasts since it first hit the market in 1993. Its ruggedness, combined with a touch of luxury, makes it stand out. One common question we get asked often is about the battery’s location. For models from 2011 to 2021, the battery is located under the passenger seat, while the first-generation Jeep Grand Cherokee’s battery is found under the hood.
So, you’re probably wondering, why would a car manufacturer put the battery in such an odd place? We asked ourselves the same question when we first discovered it. Placing the battery under the passenger seat does help with weight distribution, making your ride smoother and more balanced. Not to mention, it also protects the battery from the extreme temperatures under the hood.
If you’re considering replacing the battery yourself, knowing its location is a game-changer. Imagine trying to jump-start your Jeep in the middle of nowhere and not knowing where to look! 🛠️ We’ve been there, hands greasy and a bit frustrated, but once you know this little secret, it’s smooth sailing. Stay tuned, we’ll dive into more details and tips for a seamless battery replacement experience. 🚗

Location Of The Battery On A Jeep Grand Cherokee
Finding the battery on a Jeep Grand Cherokee can be a bit tricky, especially if you’re used to cars where the battery is right under the hood.
For the 2011-2021 Jeep Grand Cherokee:
- The primary 12-volt battery is located under the passenger seat.
- Dual battery systems might have an auxiliary battery hidden away.
Don’t worry—there are still terminal access ports under the hood to make jumpstarting easier. No more fussing around under the seat if you just need a jump.
Here’s a tip if you’re removing or replacing the battery: move the passenger seat all the way back. This will give you easier access.
For older models (before 2011):
- The batteries are right where you’d expect—under the hood, just like in most cars. You’ll find it on the passenger side.
If you’ve got one of the newer WL models, it’s still the same setup. Jeep kept it consistent, so under the passenger seat it is!
In some models equipped with the ESS system (Engine Stop/Start), there’s a dual battery setup with a smaller auxiliary battery working alongside the primary one. This can add a bit of complexity to the task but it’s nothing we can’t handle. 😉🔋
In summary:
- Primary battery (2011-2021): Under passenger seat
- Older models: Under the hood, passenger side
- ESS-equipped models: Dual battery system
Keeping this in mind, dealing with battery issues on your Jeep Grand Cherokee should be easier and less of a mystery. Happy driving! 🚗🔧
Steps To Access The Battery
When it comes to accessing the battery in a Jeep Grand Cherokee, it can be a bit tricky due to its unique location. We will break down this process into two main steps, focusing on how to open the hood and identify the battery compartment.
Opening The Hood
To start, we need to open the hood. First, locate the hood release latch, which is usually found under the dashboard on the driver’s side. Pull the latch to release the hood.
Next, go to the front of the vehicle and find the secondary latch under the hood’s center edge. Use your fingers or a flathead screwdriver to lift this latch and fully open the hood. Secure the hood with the prop rod to keep it safe and steady as we continue.
Now, with the hood open, we get a clear view of the engine bay. Look for the engine cover, which is often in the middle of the bay. This step is crucial as it sets the stage for locating the battery compartment.
Identifying The Battery Compartment
The battery’s location in the Jeep Grand Cherokee varies. For models with the battery under the hood, we will find it on the left side of the engine bay, usually near the fender. But for newer models, it’s under the passenger seat.
For under-the-hood batteries, we may need a socket wrench to remove the plastic engine cover or air filter housing. If the battery is under the passenger seat, slide the seat back, lift the carpet, and remove any covers using pliers or a socket wrench.
Next, locate the battery case and identify the positive (usually red) and negative (usually black) terminals. We can use a multimeter to check the voltage. Before disconnecting, make sure to remove any connectors and the battery vent tube.
Detach the negative terminal first using a socket wrench, followed by the positive terminal. We might also need a wire brush to clean the connectors to ensure a good connection. Now, we are ready to remove, test, or replace the battery.
Common Issues And Solutions
In our journey with the Jeep Grand Cherokee, we’ve seen specific battery problems frequently pop up. Key areas to watch out for include draining issues and corrosion at the battery terminals.
Battery Drain
A dead battery 🛠️ often comes from battery drain due to several factors like driving habits and weather conditions. If a battery’s state of charge (SOC) drops below 13V, trouble might not be far behind.
Frequent short trips 🛑 can prevent a full charge, while extreme temperatures 🌡️ are hard on the battery. Regular maintenance and using an AGM battery, which withstands jostling and temperature changes better, can help.
If the battery still dies, a jump-start can revive it but might not solve the root issue. Checking the engine cranking performance and replacing the battery if it consistently underperforms is crucial.
Corroded Battery Terminals
Battery terminals can corrode, causing a weak connection or even a failure to start. White or greenish crud 🍏 on terminals is a clear sign. It blocks electricity flow and hinders the battery’s performance.
Regularly inspect the terminals and clean them when corrosion is seen. Use a mixture of baking soda and water 🧽, scrub with an old toothbrush 🪥, and rinse it off. Wearing gloves and eye protection ✅ while doing this is important for safety.
Ensuring terminals are tight and applying a protective layer of petroleum jelly can help avoid future buildup. Consistent checks as part of regular maintenance 🔧 can keep problems at bay.
Safety Precautions
Handling your Jeep Grand Cherokee’s battery with care is crucial to avoid injuries and damage. We’ll cover wearing protective gear and disconnecting the battery safely, making sure you stay safe every step of the way.
Wearing Protective Gear
When dealing with a car battery, protective gear is vital. Safety goggles shield your eyes from harmful splashes. Even tiny battery acid droplets can cause severe eye injuries. We should also wear hand gloves or protective gloves. These non-conductive gloves provide a barrier against electric shocks.
Wearing long sleeves and closed-toe shoes adds an extra layer of protection. It’s surprising how easy it is to get battery acid on your skin while working on your vehicle. Remember, safety first! ⚠️ Don’t forget to inspect your gloves for tears or holes before starting. 🔧
Disconnecting The Battery Safely
Before you start, make sure all electrical devices inside the Jeep are off. This prevents any unexpected sparks. Begin by disconnecting the negative terminal first. Using a wrench, carefully loosen the bolt and remove the black cable. Next, move on to the positive terminal, repeating the process.
Avoid touching both terminals simultaneously, as this can cause a shock. ⚡ Once disconnected, place the cables away from the battery to prevent accidental reconnections. Here’s a tip: wrap the cable ends with electrical tape for extra safety. 🚨 Also, consider using a battery terminal puller to avoid damaging the posts.
By following these steps, you’ll ensure a safe and smooth battery disconnect procedure.
