Jeep owners might find it perplexing that their car battery is not located underneath the hood like in most cars.

Locating the battery becomes challenging for a simple jump-start or replacement when it is not easily visible.

So, where does one find the battery in a Jeep Grand Cherokee?


Where Is The Battery In A Jeep Grand Cherokee?


Contrary to most cars, the Jeep Grand Cherokee houses its battery beneath the passenger seat, accessible by adjusting the seat to the most forward and upright position.

Terminal access points are present on the passenger side of the engine compartment under the hood.

Getting accustomed to the unique battery placement in a Jeep may take some time, but by the end of this article, you’ll be well-acquainted with the specifics of your Jeep Grand Cherokee.



Why Is The Battery Under The Passenger Seat?


Jeep manufacturers’ decision to place the battery, typically an easily serviced and accessed component, under the passenger seat instead of the engine compartment hood leaves some Jeep owners scratching their heads and cursing.

The decision to position the battery beneath the passenger seat, a practice not new to Jeep and reminiscent of the original WWII Jeeps, pays homage to the historical design and serves a functional purpose.

In the original design, the battery was situated under the seat beneath the floorboards.

One possible rationale is that lead-acid batteries cannot function effectively above 120°F, and placing the battery next to the hot radiator under the hood might be unsuitable.

Furthermore, manufacturers may have opted to allocate precious space in the engine compartment for the engine and other essential parts.


Batteries In Different Jeep Grand Cherokee Model Years


From 2011 to 2021 Jeep Grand Cherokees, the 12-volt battery is positioned beneath the passenger seat.

However, for added convenience in jumpstarting the vehicle, there are terminal access ports under the hood.

In older models, the battery is traditionally located under the hood, similar to typical cars.

The battery utilized in Jeep Grand Cherokee Models from 2011 onwards is an Absorbent Glass Mat (AGM) battery, recognized as one of the most technologically advanced in the realm of lead-acid batteries.

AGM batteries are preferred for their resilience against intense shock and vibrations, making them suitable for off-road vehicles like Jeeps.

Constructed with fibreglass material instead of gel, these batteries offer increased stability.

During the replacement of such batteries, it’s important to note the presence of special vents designed to eliminate vapours.

Additionally, caution should be exercised as typical battery chargers are not deemed safe for use with AGM batteries.

Charging AGM batteries should follow a low and slow approach due to their specific voltage ranges.

Failure to adhere to these guidelines may lead to a shortened battery life.


How Do You Remove A Battery From A Jeep Grand Cherokee?


To Remove the Battery from a Grand Jeep Cherokee, follow these steps:

  1. First, slide and lean the passenger seat all the way forward (towards the windshield).
  2. Secondly, remove the carpeted panel by pulling at the edge.
  3. Thirdly, loosen the fastener for the negative battery cable with a wrench.
  4. Fourthly, remove the negative battery cable from the negative battery terminal.
  5. Then, remove the vent tube from the side of the battery.
  6. Next, remove the two fasteners from the battery hold-down plate with a wrench.
  7. Next, loosen the fastener for the positive battery cable and remove the cable from the terminal.
  8. Lastly, remove the old battery from the vehicle. This might take some wiggling and maneuvering to get it out from under the seat.

Keep in mind that a new battery typically lasts three to five years, depending on weather conditions, driving habits, and the battery size.
