This automotive maintenance tutorial was specifically written to assist owners of the updated (2011, 2012, 2013 and 2014) Dodge Avenger sedan in changing the 12 volt automotive battery located in the front driver side wheel well.

Owners of other Chrysler Group vehicles such as the Dart, Challenger, Durango, Charger, Grand Caravan, 200, 300, RAM C/V Tradesman, Jeep Patriot, Compass and Cherokee may also find these DIY instructions to be helpful.

The Chrysler Group LLC brand OEM battery in this 2012 Avenger is part number 56041380AE.

A few other compatible Group Size 86 replacement batteries include the EverStart MAXX-86 from Wal-Mart, AutoCraft 86-1, Napa BAT 7586 or BAT 8486, and Duracell SLI86 or SLI86M.

The tools needed to replace the 12V battery include a lug nut wrench, a floor jack, two jack stands, a 7mm socket with a 1/4" drive ratcheting wrench, a flathead screwdriver, a 13mm socket with a 3/8" drive ratcheting wrench and a 10mm socket.

Replace Front Wheel
Push On Plastic Hub Cap
Spin On 5 Lug Nuts

Lower Car From Stands
Torque To 100 ft-lbs
Slightly tighten the lug nuts in a "criss cross" or "star" pattern with the tire iron.

Lower the car from the jack stands and the floor jack.

Continue progressively tightening the lug nuts in the clockwise direction in a star pattern to about 1/4 turn past hand tight or 100 ft-lbs of torque. It would be best to use a torque wrench or an impact wrench with a torque stick to properly tighten the lug nuts.

Test the new 12V automotive battery by starting the engine and turning on the headlights.

It would be a good idea to check that the lug nuts are still tight after your next trip.
