1/4 Turn Counterclockwise

This automotive maintenance tutorial was specifically written to assist owners of the first generation (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 & 2016) Jeep Patriot SUV in changing a dead 12 volt car battery in the engine bay.

Owners of other Jeep, Dodge, Chrysler, Fiat and RAM vehicles such as the Compass, Renegade, Wrangler, Grand Cherokee, Cherokee, 500, Town & Country, 200, 300, Pacifica, Challenger, Charger, Dart, Durango, Journey, Grand Caravan, RAM 1500, C/V Tradesman and ProMaster Van may also find these DIY instructions to be helpful.

The OEM battery is a Chrysler Group LLC 56041380AE.

A few other compatible "Group Size 86" batteries with their part numbers are as follows: Optima 8025-160 25, EverStart MAXX-86, Mopar BB086525AA, Bosch 86-630B, ProStart 86-525PS, NAPA Legend BAT 7586 or BAT 8486, Bosch S4567B and AutoCraft 86-1 or 86-2.

The tools needed to access and replace the battery include a 10mm socket, a 13mm socket, an extension bar and a ratcheting wrench.

Old 12 Volt Battery
The first two steps are to open the hood and then move to the right side of the engine bay.

The 12V car battery is located under the air intake housing and in front of the engine air filter housing.

Release the two fasteners that secure the air intake assembly in place by turning them 1/4 turn counterclockwise.

Gently lift the air intake out of the engine bay and set it aside in a safe place.

Once the air intake is out of the way, you'll see the OEM 12 volt battery.

Remove Old 12V Battery
Loosen the bolt at the front bottom edge of the battery with a 13mm socket and ratcheting wrench.

Set the 13mm bolt aside in a safe place.

Remove the black plastic battery clamp block.

Lift the old battery out of the engine bay.

Try to avoid dropping or tipping over the old battery to prevent from having battery acid leak out.

Be sure to take the old battery with you to Walmart or the auto parts store to avoid having to pay a "core" charge. The retailer will also have the old battery properly recycled.

I recommend buying the Optima RedTop 8025-160 25 battery since it has excellent reviews on Amazon.

Clean off any debris from the plastic battery tray so that the new battery will rest evenly on it.
