One Battery-Two ways of jump starting car!
Jimmy,
Hello, This is Brian Carotenuto. Just to clarify something for you. Our 300's and Magnum's have one battery, located in the trunk, under the spare tire cover, next to the spare tire on the right side of the trunk. There are auxillary posts for jump starting the car located in the engine compartment on the passenger side of the engine compartment area. The positive post up front is located under a red cover next to the Power Distribution Center, otherwise known as where some of the fuses and relays are located, that are used to power the vehicle accessories and features. The other connection is the ground wire. I hope this information helps.
Sincerely yours,
Brian T. Carotenuto
