Owners of other Chrysler, Dodge and RAM vehicles such as the Town & Country, 300, 200, Avenger, Charger, Journey, Dart, Durango, Grand Caravan, and Ram C/V Tradesman minivan may also find these DIY instructions to be helpful.

A few compatible replacement "Group Size" H7 or 94R batteries with part numbers are as follows: ACDelco 94RAGM,  Exide FP-AGML4/94R, EverStart Platinum AGM H7, EverStart MAXX-H7, Bosch 94R730B or 94R800BAGM, NAPA Legend 9894R or 7594R and AutoCraft 94RH7 or H7-AGM.

The tools needed to complete this procedure include a 10mm socket, an extension bar and a 1/4" drive ratchet.

Open the trunk lid and lift the carpeted trunk mat to access the battery.

Press the metal release tab on the vinyl strap that holds the battery in place and loosen it a few inches.

Then loosen the negative "-" battery terminal by turning the nut counterclockwise with the 10mm socket and ratcheting wrench.

Cover the terminal with a small towel and tuck it away on the side of the trunk to help prevent accidental contact.

Pull the red plastic cover off the positive "+" terminal and set it aside in a safe place.

Pull the positive terminal straight off the "+" battery post.

Don't forget to pull out the rubber exhaust vent hose from the rear of the battery.

Loosen the 10mm battery hold down bar bolt by turning it counterclockwise.

Remove the bolt and set it aside in a safe place.

Carefully lift the old battery out of the trunk and gently set it down on the ground.

Try to avoid tipping or dropping the old battery to prevent from cracking it and/or having battery acid leak out.

If you can wait a day or two, I recommend buying the ACDelco 94RAGM battery from Amazon since it has great reviews.

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

Carefully lower the new 12 volt battery down in to the trunk and on to the plastic tray.

Make sure the new battery is orientated with the positive "+" battery post closer to the front of the car and the negative "-" battery post near the rear bumper to match the orientation of the old battery.

If you've had a problem with corrosion (white or blue powder) building up on the terminals or the battery posts, I recommend installing some felt anti-corrosion washers over the battery posts.

Push the positive battery terminal on to the "+" battery post near the rear of the trunk.

Tighten the 10mm terminal nut by turning it clockwise with the socket and ratcheting wrench.

Replace the silver metal battery clamp bar at the rear edge of the battery (close to the back bumper).

Line up the bolt hole in the clamp bar with the bolt hole on the battery tray.

Check that the battery can not be moved, slid or wiggled on the plastic tray. If it can be moved, tighten the clamp bolt an extra turn or two.

Try to avoid over tightening the battery hold down bar to prevent from cracking the plastic battery housing which may cause an acid leak.

Push the negative terminal straight on to the "-" battery post.

Tighten the 10mm battery terminal in the clockwise direction until it is snug.

Do not over tighten the terminal nut to prevent from damaging the battery post.

Lower the carpeted trunk mat down in to place to cover the spare tire and battery.

Be sure to record the battery change in your car's service records.
