In the 2016 Jeep Grand Cherokee, the battery is located under the passenger seat like all models made from 2011 and on. However, in addition to the primary battery that turns the engine over, there is a second auxiliary battery which is also located underneath the passenger seat.

Why is the Battery Under the Passenger Seat?

This isn’t a new innovation, especially for Jeep. In the original Jeeps designed for WWII, the battery was located under the seat beneath the floorboards. This design pays homage to the original design but also serves a functional purpose.

One reason might be that lead-acid batteries cannot operate above 120°F. The radiator can get very hot, so it isn’t suitable for the battery to be snuggled up next to it.

Additionally, the manufacturers may have preferred to use precious engine compartment space for the engine and other parts.
