Battery Care Tips for Your Dodge Durango
- HEMI and Hellcat Durangos require high-CCA AGM batteries — never substitute.
- eTorque systems use auxiliary batteries that need periodic inspection — not just the main battery.
- Winter cranking power matters for V8 engines — load-test annually before cold weather.
- Hellcat owners: heavy electrical loads (audio systems, performance accessories) shorten battery life — check annually.
- Expected lifespan for AGM batteries is 4-6 years in this climate.
