If You own a 2018 Chrysler Pacifica, You may need to find Your auxiliary battery. This is a battery that exists as a sort of back up, secondary to the primary battery under the hood. This battery enables the vehicle components to continue working in the event of loss of charge from the primary battery. You can find it easily. First, open the passenger door on the vehicle, and look in the footwell. Lift up the carpet. The auxiliary battery is located beneath it. If You need to replace the battery, You can expect to pay between $67 and $163 for parts alone. If You choose to have it replaced by a mechanic, You can expect to pay between $34 and $102 for labor.

Under the hood next to the main battery.^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Under the hood, to the left of the primary battery, easily identified with it's own positive and negative post.

I have a small second battery in my 2018 Pacifica directly to the left of the main battery under the hood. I haven't checked to see if there is a 3rd batter under the passenger floorboard.

Marie's posting is plagiarized (stolen) word-for word from the AutoZone web site on where to find the aux battery on a 2018 Pacifica. Not nice. You should have provided a link to AutoZone or cited them as your source of information.
