On a 2015 Jeep Grand Cherokee, the battery is located beneath the passenger side front seat, not under the hood. This unusual placement is a common source of confusion for owners who first look under the hood and find only a fuse box. Knowing exactly where is the battery on a 2015 Jeep Grand Cherokee saves you time and frustration, especially if you need a jump start or replacement.
The battery sits in a plastic tray directly under the front passenger seat. It is secured with a metal bracket and covered by a plastic access panel. This design helps protect the battery from engine heat and frees up space under the hood for other components.
Where Is The Battery On A 2015 Jeep Grand Cherokee
Let’s get straight to the point. The battery is located under the passenger side front seat. You need to move the seat all the way forward to access the battery compartment. This location applies to all trim levels of the 2015 Grand Cherokee, including Laredo, Limited, Overland, and Summit.
Do not waste time looking under the hood. There is no battery there. Instead, you will find a remote jump start terminal under the hood, but the actual battery is inside the cabin.
Why Is The Battery Under The Seat
Jeep engineers placed the battery under the passenger seat for several practical reasons. First, it keeps the battery away from extreme engine heat, which can shorten battery life. Second, it improves weight distribution for better handling. Third, it frees up space under the hood for the engine and other components.
This location also protects the battery from water and mud when off-roading. However, it does make accessing the battery a bit more involved than a traditional under-hood location.
Tools You Will Need
Before you start, gather these tools:
- 10mm socket wrench or ratchet
- Extension for the socket wrench (optional but helpful)
- Flathead screwdriver
- Gloves (battery acid can be dangerous)
- Safety glasses
You may also need a memory saver device if you are replacing the battery. This prevents your radio presets and other settings from being lost.
Step-By-Step Guide To Access The Battery
Follow these steps carefully. The process is straightforward but requires patience.
- Park the vehicle on a level surface and turn off the engine. Remove the key from the ignition.
- Open the front passenger door fully. You need clear access to the seat area.
- Move the passenger seat all the way forward using the power or manual adjustment controls.
- Look under the front of the seat. You will see a plastic cover with a tab or latch.
- Use a flathead screwdriver to gently pry open the plastic cover. It may have two clips holding it in place.
- Once the cover is removed, you will see the battery sitting in a black plastic tray. There is a metal hold-down bracket across the top.
- Use the 10mm socket wrench to remove the bolt securing the hold-down bracket. Set the bracket aside.
- Now you can see the battery terminals. The positive terminal is usually red, and the negative is black.
- Disconnect the negative terminal first using the 10mm socket. Then disconnect the positive terminal.
- Carefully lift the battery out of the tray. It may be heavy, so use both hands.
If you are only jump-starting the vehicle, you do not need to remove the battery. You can connect jumper cables directly to the terminals under the seat.
Jump Starting From Under The Hood
If you cannot access the battery under the seat, there is a remote jump start terminal under the hood. This is located in the fuse box on the passenger side of the engine bay.
Open the hood and look for a red plastic cover with a plus sign. Lift the cover to expose the positive terminal. The negative terminal is a metal bolt on the strut tower or engine block. Do not connect the negative cable to the battery directly under the hood because there is no battery there.
Connect the positive cable to the red terminal under the hood. Connect the negative cable to the metal ground point. Then start the vehicle. This method is safer and easier than crawling under the seat.
Common Issues With This Battery Location
There are a few problems you might encounter. The plastic cover under the seat can break if you pry too hard. Be gentle. Also, the battery terminals can corrode because the location is not well ventilated.
Another issue is that the battery tray can collect debris like dirt or spilled drinks. Clean the tray before installing a new battery. If the hold-down bracket is rusted, you may need to replace it.
Some owners report that the battery drains faster in this location because the cabin temperature can be higher than under the hood. However, this is rare.
Battery Specifications For The 2015 Jeep Grand Cherokee
When replacing the battery, you need the correct size and type. The 2015 Grand Cherokee uses a Group 94R battery. This is a standard size with top posts.
- Voltage: 12 volts
- Cold Cranking Amps (CCA): 700 to 800
- Reserve Capacity: 120 minutes or higher
- Terminal Location: Left positive, right negative
You can use an AGM (Absorbent Glass Mat) battery for better performance. AGM batteries are more resistant to vibration and last longer. However, they cost more than standard lead-acid batteries.
Check your owner’s manual for the exact specifications. Some trim levels may require a different battery group size.
How To Replace The Battery Yourself
Replacing the battery is a DIY job if you are comfortable with basic tools. Follow the steps above to remove the old battery. Then install the new battery in reverse order.
- Place the new battery in the tray. Make sure the terminals are oriented correctly.
- Reinstall the hold-down bracket and tighten the bolt.
- Connect the positive terminal first, then the negative terminal. Tighten both securely.
- Replace the plastic cover under the seat.
- Move the seat back to its normal position.
- Start the vehicle to confirm the battery is working.
After installation, you may need to reset the clock, radio presets, and power window settings. Some vehicles also require a battery registration procedure if you have a start-stop system. Check your owner’s manual for details.
Safety Precautions
Working with batteries involves some risk. Always wear gloves and safety glasses. Battery acid can burn your skin and eyes. Do not smoke or create sparks near the battery.
Disconnect the negative terminal first to prevent short circuits. When reconnecting, connect the positive first. This reduces the risk of accidental grounding.
If you spill battery acid, neutralize it with baking soda and water. Rinse the area thoroughly. Dispose of the old battery at a recycling center. Do not throw it in the trash.
When To Call A Professional
If you are not comfortable working under the seat, call a mechanic. The battery location can be tricky if you have limited mobility or if the seat is stuck. Also, if the battery terminals are heavily corroded, a professional can clean them safely.
Some dealerships and auto shops charge around $50 to $100 for battery replacement. This includes disposal of the old battery. It may be worth the cost if you value your time.
