Dodge Durango Battery

Supporting the V8 engine, three-row seats and impressive towing capacity in this powerful people mover is a powerful battery (or two, in some models.)

Starting in 2011, the Dodge Durango made the switch from a BCI group size 65 to DIN battery sizes 94R/H7 or 48/H6 if it’s a start-stop model between 2016-2021. Also, since 2011, the Dodge Durango battery is located under the front passenger seat. That means, among other things, you should make sure you attach a vent hose whenever replacing a battery on a Dodge Durango.

Which Dodge Durango requires two batteries? Durangos with start-stop engines from model years 2017-2021 require an auxiliary battery, the MTX-AUX14. Why two? The Dodge Durango requires a lot of onboard power, and the auxiliary battery supports the main battery between engine starts.

The Dodge Durango may require 650 to 800 cold cranking amps (CCA), depending on the engine size and whether it comes with a special service package. If your Dodge Durango has a special service package, it will need a 49/H8 battery.

Dodge Durango models from 1998 to 2007 require a group 65 or a 27, depending on options and engine size.

Check your vehicle’s VIN and owner manual to verify that you have the correct fit for your vehicle.

Before purchasing a replacement battery, verify specifications by checking under the hood or consulting your owner's manual. This step ensures you select the proper battery for your vehicle’s needs.

Choosing the right battery guarantees optimal performance and avoids issues like a dead battery or warning battery light.

Consider consulting battery experts or visiting an Interstate All Battery Center for assistance.

Dodge Durango Batteries Usually Last 3-5 Years

The typical car battery lasts 3-5 years, depending on a few factors:

• battery type
• climate
• driving patterns
• vehicle maintenance

Some models of the 2017-2021 Dodge Durango require an auxiliary battery, a second car battery to support the start-stop engine inside. Make sure you replace both batteries at the same time. A weak auxiliary battery can drag down the other battery, even if it’s new.

If you notice any of these signs or are uncertain about the condition of your Dodge Durango battery, it's recommended to have it tested by the battery pros at Interstate All Battery Center or your nearest repair shop.

A battery test can assess its actual state and provide guidance on whether to consider a Dodge battery replacement.

Get the Most out of Your Dodge Durango Battery

Keeping your Durango battery in top shape can save time and money. Here's how to prolong its life:

1. Get a Battery Test with Every Oil Change: Battery tests can identify a weak battery well before you can notice any warning signs of a battery about to die.
2. Manage Corrosion: Inspect your battery for corrosion build-up on the battery and battery cables, or fluid in the battery tray. If present, it may be time for a replacement, or cleaning at the very least. Use a wire brush and a proper battery cleaning solution to remove corrosion regularly.
3. Watch for Warning Signs: Sluggish starts on cold warnings, flickering headlights when idle or parked and even glitches in your electronics may all be signs of a battery about to die. If you notice one of these warning signs, run over to a trusted repair shop for a battery test.
4. Insist on AGM Batteries: Trust AGM batteries for start-stop models as well as any high-powered vehicles, like the Dodge Durango. This SUV is particularly sensitive to dips in voltage. To protect your people mover, get regular battery tests and make sure you choose only AGM batteries.
