2017 Ram 1500 Battery Size & Group

Quick Answer

• BCI Group Size: H7/94R (gasoline engines)
• CCA Rating: 700-800 CCA (minimum, depending on engine and original equipment)
• Reserve Capacity: 130-150 minutes (minimum)
• AGM vs. Flooded: Most 2017 Ram 1500s came with flooded lead-acid batteries. However, AGM batteries are a popular and often superior upgrade.
• Terminal Layout: Top post, typically positive on the right.
• Physical Dimensions: Approximately 12.4" L x 6.9" W x 7.5" H.
• Dual-Battery Setup: Not applicable for typical gasoline 2017 Ram 1500 models.

Replacement Battery Options

When it's time to replace the battery in your 2017 Ram 1500, you have several excellent choices. Below are some popular replacement brands and their common offerings for the H7/94R group size. Always double-check fitment with your specific vehicle before purchasing.

• Interstate Batteries: Often available in various CCA ratings for the H7/94R group, such as the MT7-94R (flooded) or MTZ-HP7/94R (AGM).
• Optima Batteries: While Optima is known for its YellowTop and RedTop batteries, a direct H7/94R equivalent is not always readily available in their standard lineup. Some owners may opt for a different group size with adapter kits, but this is not a direct fit.
• DieHard Batteries: DieHard Platinum AGM (Group H7) and DieHard Gold (Group H7) are popular choices, offering strong CCA and reserve capacity.
• Odyssey Batteries: Odyssey Extreme Series (e.g., ODP-AGM94R H7) provides excellent performance and durability in an AGM form factor.
• ACDelco Batteries: ACDelco Professional (e.g., 94RAGM for AGM) or Advantage (flooded) series are common OEM-style replacements.

AGM vs. Flooded — Which Does This Vehicle Need?

The 2017 Ram 1500 typically came from the factory with a conventional flooded lead-acid battery. However, upgrading to an Absorbed Glass Mat (AGM) battery is a popular choice and often recommended. AGM batteries offer several advantages:

• Durability: Better resistance to vibration and impacts.
• Maintenance-Free: Sealed design means no water checks or acid leaks.
• Deep Cycle Capabilities: Better suited for vehicles with more electronics or frequent short trips.
• Faster Recharging: Generally recharge quicker than flooded batteries.
• Consistent Power: Provide more consistent power output throughout their lifespan.

While an AGM battery is not strictly required for your 2017 Ram 1500, its benefits in terms of lifespan, performance, and resistance to environmental factors make it a worthwhile investment for many owners. If your Ram 1500 has start/stop technology (which some higher trims or specific engine configurations might have), an AGM battery is indeed required for proper operation.

Post-Installation Relearn / Reset Procedure

After replacing your battery, it's a good idea to perform a "relearn" or "reset" procedure to ensure all vehicle systems (especially the battery monitoring system) recalibrate correctly. For the 2017 Ram 1500, a simple reset often involves:

1. Connecting the new battery: Ensure terminals are clean and connections are secure.
2. Starting the vehicle: Drive the vehicle for at least 10-15 minutes, allowing the engine computer (PCM) to relearn idle parameters and the battery monitoring sensor to calibrate.
3. Window Express Up/Down Reset: If your power windows lose their "express" function, you may need to reset them. To do this, fully lower the window, then hold the switch up until the window is fully closed, and continue holding it for an additional 2-3 seconds.

Some more advanced procedures might involve disconnecting the negative terminal for a prolonged period (e.g., 30 minutes) to clear adaptive memory, but for most battery replacements, the above steps suffice. If you experience any persistent issues or warning lights, consult your owner's manual or a qualified technician.

Signs of a Failing Battery

Don't wait until your Ram 1500 leaves you stranded. Watch for these common signs of a dying battery:

• Slow Engine Crank: The most common sign. The engine turns over sluggishly when you try to start it.
• Dim Headlights/Interior Lights: Especially noticeable when the engine is off or cranking.
• Warning Lights: A battery warning light on your dashboard.
• Corrosion on Terminals: Excessive white or blue corrosion around the battery terminals.
• Swelling Battery Case: The battery case looks warped or swollen, indicating internal damage.
• Electrical Gremlins: Intermittent issues with infotainment, power windows, or other electronics.
• Old Age: Car batteries typically last 3-5 years, depending on climate and usage.

Common Battery Issues for This Generation

The 2017 Ram 1500, like many modern trucks, relies heavily on its electrical system. Common battery-related issues for this generation can include:

• Parasitic Draws: Aftermarket accessories or even faulty OEM components can slowly drain the battery when the vehicle is off.
• Short Trips: Frequent short drives don't always allow the alternator to fully recharge the battery, leading to premature wear.
• Extreme Temperatures: Both very hot and very cold temperatures significantly impact battery life and performance.
• Intensive Electrical Load: Features like Uconnect, heated seats, and advanced safety systems place a considerable demand on the battery.

Regular battery testing, especially as your battery ages, can help you preemptively replace it and avoid unexpected breakdowns.
