If you own a 2017 Jeep Grand Cherokee, you may wonder where the battery is located. This question comes up often because finding the battery is not as simple as with many other vehicles. The Grand Cherokee is a popular SUV, known for its mix of comfort, power, and off-road ability. However, when it comes to maintenance, especially something basic like replacing the battery, things can get confusing. In this article, you will learn exactly where the battery is, how to access it, and important details you should know as a Jeep owner.
Understanding The Battery Location
Unlike most cars where the battery sits under the hood, the 2017 Jeep Grand Cherokee does things differently. The main battery is not found in the engine bay. Instead, it is placed in a more hidden area, which surprises many first-time owners. This design is meant to protect the battery from engine heat and weather, but it also means you need to know exactly where to look.
Where Is The Battery On A 2017 Jeep Grand Cherokee?
The primary battery is located under the passenger seat. To access it, you need to slide the seat forward and look underneath. This location helps keep the battery cooler and safer, but getting to it takes a few extra steps. Here’s how you find it:
- Open the passenger side door.
- Move the front passenger seat as far forward as possible.
- Look underneath the seat for a black plastic cover. The battery sits beneath this cover.
- Remove the cover by pulling the tabs or unscrewing bolts, depending on your model.
After removing the cover, you will see the battery and its terminals. You can now disconnect and replace the battery as needed.
Why Did Jeep Place The Battery Under The Seat?
Jeep made this choice for several reasons:
- Heat protection: Batteries last longer when they are kept away from engine heat.
- Space: The engine bay is crowded in modern SUVs. Placing the battery under the seat frees up space for other parts.
- Weather safety: The battery is shielded from rain, snow, and road salt.
This design helps with durability, but it also makes battery changes a bit more complex.
Is There A Second Battery?
Some models of the 2017 Grand Cherokee have a second, smaller battery called the auxiliary battery. This is used for the stop/start system, which saves fuel by turning off the engine when you stop at lights. The auxiliary battery is also found under the passenger seat, next to the main battery. If your Jeep has this feature, both batteries may need replacement at the same time.
Steps To Replace The Battery
Changing the battery is not as quick as in older cars, but it is still possible for most people. Here’s a simple process:
- Turn off the engine and all electronics.
- Move the passenger seat forward.
- Remove the floor mat (if present).
- Find and remove the battery cover.
- Disconnect the negative terminal first, then the positive.
- Carefully lift out the old battery.
- Place the new battery in the same position.
- Connect the terminals: Positive first, then negative.
- Replace the cover and seat.
Remember to check if your Jeep has an auxiliary battery. If it does, follow the same steps for both.
Comparison: Battery Location Vs Other Suvs
Here is a quick comparison between the Jeep Grand Cherokee and other popular SUVs:
| Vehicle Model | Battery Location | Ease of Access |
|---|---|---|
| Jeep Grand Cherokee (2017) | Under passenger seat | Moderate |
| Toyota Highlander | Under the hood | Easy |
| Ford Explorer | Under the hood | Easy |
| Chevrolet Tahoe | Under the hood | Easy |
The Grand Cherokee’s battery is less accessible than most competitors. This is important to know before starting the replacement.
Battery Specifications For The 2017 Jeep Grand Cherokee
You should use a battery that matches the original specifications. Here’s what you need:
| Battery Type | Group Size | Cold Cranking Amps (CCA) | Reserve Capacity (min) |
|---|---|---|---|
| Main Battery | Group 94R | 850 | 140 |
| Auxiliary Battery | Group 400 | 200 | 23 |
Always double-check your owner’s manual or consult your dealer to confirm the exact battery specs.
Common Mistakes When Changing The Battery
Many owners make mistakes when replacing the battery. Here are two that are often missed:
- Not disconnecting the negative terminal first: This can cause short circuits and damage electronics.
- Forgetting to reset electronic systems: After replacing the battery, some systems may need to be reset or reprogrammed. This includes the radio, power windows, and sometimes the ECU.
Another less obvious mistake is failing to check for the auxiliary battery. If your Jeep has the stop/start system, always check for two batteries.
Useful Tips For Battery Maintenance
Keeping your battery healthy is important. Here are some tips:
- Clean terminals regularly to prevent corrosion.
- Drive regularly to keep the battery charged.
- If your Jeep is parked for a long time, use a battery maintainer.
- Check battery voltage with a multimeter every few months.
A well-maintained battery can last up to five years in the Grand Cherokee. Extreme weather and infrequent driving reduce battery life.
What To Do If You Can’t Find The Battery
If you still have trouble locating the battery, check your owner’s manual. You can also visit the official Jeep website or contact your dealer for help. There are many online guides and videos that show the process step by step. For more detailed information, you can visit Jeep Official Site.
