2019 Ford F-250 Super Duty Battery Size & Group

Quick answer

• BCI Group Size: Group 65 (gasoline engines), Dual Group 65 or Group 31 (diesel engines)
• CCA Rating (minimum): 800 CCA (gasoline), 750 CCA per battery (diesel)
• Reserve Capacity (minimum): 140 minutes
• AGM vs. Flooded: Most F-250s come with flooded batteries from the factory. AGM is an excellent upgrade for extended life and better performance, especially with modern electronics.
• Terminal Layout: Top post, standard (SAE) terminals.
• Physical Dimensions (Group 65): Approximately 12" L x 7.5" W x 7.5" H
• Dual Battery Setup: Diesel models utilize two batteries wired in parallel for increased cranking power.

Replacement battery options

Here are some popular replacement battery options for your 2019 Ford F-250 Super Duty. Always verify the group size and specifications to ensure compatibility.

• Interstate: MTZ-65 (AGM), MTP-65 (Flooded)
• Optima: YellowTop H6/Group 48 (Note: This is a common Optima offering, but verify fitment for Group 65 applications)
• DieHard: Platinum AGM Group 65, Gold Group 65 (Flooded)
• Odyssey: Extreme Series Group 65 (ODP-AGM65)
• ACDelco: Professional AGM Group 65, Professional Flooded Group 65

AGM vs. flooded — which does this vehicle need?

Your 2019 Ford F-250 Super Duty likely came equipped with a traditional flooded lead-acid battery from the factory. While a standard flooded battery will work as a direct replacement, an Absorbent Glass Mat (AGM) battery offers several advantages that make it a compelling upgrade for your F-250.

AGM batteries are sealed and maintenance-free, offering superior vibration resistance, a slower self-discharge rate, and better performance in extreme temperatures. They are also designed to handle the increased electrical demands of modern vehicles, which often feature more onboard electronics, infotainment systems, and start-stop technology (though rare on this generation F-250, it's good to be prepared). For trucks used for heavy towing, plowing, or with aftermarket accessories drawing significant power, an AGM battery provides enhanced reliability and longevity.

Ultimately, either type will function, but an AGM battery will generally provide better long-term value and performance for the demanding nature of a Super Duty truck.

Post-installation relearn / reset procedure

After disconnecting and replacing the battery in your 2019 Ford F-250 Super Duty, it's important to follow a few steps to ensure all systems reset correctly. While the F-250's Battery Monitoring System (BMS) is designed to re-learn, a manual reset can sometimes be beneficial, especially if a new battery with different specifications is installed.

1. After Battery Installation: Ensure the battery terminals are clean and securely tightened.
2. Idle Relearn: Start the truck and let it idle for at least 5-10 minutes. This allows the engine control unit (ECU) to re-learn idle parameters.
3. Drive Cycle: Drive the vehicle for a short period (10-15 minutes) with varying speeds and stops. This helps other modules re-learn their operational parameters.
4. Window Express Up/Down (if equipped): If your power windows have an "express up/down" feature that no longer works, cycle the window fully down and hold the switch for a few seconds, then fully up and hold for a few seconds. Repeat for all affected windows.
5. Radio Presets: You will likely need to re-enter your radio station presets.
6. Optional BMS Reset (Dealer/Scan Tool Recommended): For a complete reset of the Battery Monitoring System, a specific procedure involving illuminating the high beams, pressing the brake pedal, and other steps can be performed if a scan tool isn't available. However, for most DIY replacements, the system will eventually re-learn on its own. If you experience persistent electrical issues, consulting a dealership or using an advanced scan tool for a full BMS reset is recommended.

Signs of a failing battery

• Slow Cranking: The engine turns over sluggishly when you try to start it.
• Dim Lights: Headlights and interior lights appear dim, especially when starting the truck.
• Warning Lights: A battery or charging system warning light illuminates on your dashboard.
• Corrosion: Excessive corrosion around the battery terminals can indicate a poor connection or an expiring battery.
• Swollen Battery Case: The battery case appears bloated or swollen, often a sign of internal damage or overcharging.
• Age: Most automotive batteries last 3-5 years. If your battery is older than this, it's on borrowed time.
• Electrical Gremlins: Unexplained electrical issues like flickering lights, malfunctioning accessories, or erratic gauge readings.

Common battery issues for this generation

For the 2019 Ford F-250 Super Duty, several factors can contribute to battery premature failure or issues:

• High Electrical Demand: Modern trucks, especially Super Duty models, have a significant number of electronic modules, sensors, and accessories. Even when the truck is off, these systems draw a small amount of power (parasitic draw), which can eventually drain a weaker battery.
• Diesel Engine Demands: Diesel engines require much more cranking power than gasoline engines, especially in cold weather. The dual-battery setup is crucial here, and if one battery starts to fail, it puts extra strain on the other, leading to accelerated wear.
• Frequent Short Trips: If your F-250 is primarily used for short trips, the alternator may not have enough time to fully recharge the battery, leading to a state of partial charge and reduced lifespan.
• Aftermarket Accessories: Lift kits, elaborate lighting setups, winches, and powerful audio systems can significantly increase electrical demand, sometimes exceeding the capacity of the factory charging system and battery if not properly accounted for.
• Temperature Extremes: Both extreme heat and extreme cold can shorten battery life. Heat accelerates the internal chemical reactions, while cold reduces a battery's available power.
