Some Dodge Durango models feature two batteries: a main battery and an auxiliary battery. The main battery powers the engine and standard electrical systems, while the auxiliary battery supports start-stop technology and additional electronics. This setup helps improve fuel efficiency and ensures reliable operation of features like climate control and infotainment, even when the engine is off. If you're replacing a battery, check your owner's manual or consult a professional to identify which battery needs attention.

Dodge Durango vehicles typically use automotive batteries from specific group sizes, such as Group 65, H6, H7, or 94R. The right battery depends on your Durango's model year and trim. Always verify compatibility by checking your owner's manual or using Walmart's online tools to match the battery group size and cold cranking amps (CCA) to your vehicle's requirements. Choosing the correct battery ensures reliable performance and proper fit.

In most cases, you won't need to reprogram your Dodge Durango after a battery replacement. However, some newer models may require resetting certain electronic systems, like the clock, radio presets, or power windows. If your vehicle has advanced features, consult your owner's manual for specific instructions or ask a certified technician. It's a good idea to keep any security codes handy before starting the battery change process.

Signs that your Dodge Durango's battery may need replacing include slow engine cranking, dim headlights, or warning lights on your dashboard. If your vehicle struggles to start or electronics behave unpredictably, it's wise to test the battery's voltage. Walmart offers battery testing services, and you can also use a multimeter at home. Regular checks help prevent unexpected breakdowns and keep your Durango running smoothly.

Yes, you can usually replace your Dodge Durango key fob battery at home. Most key fobs use coin-style batteries like CR2032 or CR2025. To change it, gently open the fob case with a small tool, remove the old battery, and insert the new one—making sure the polarity matches. After replacement, test the fob to ensure it's working. If you're unsure, Walmart's automotive department can assist or provide replacement batteries.
