2024 Ford F-350 Super Duty Battery Size & Group

Quick Answer

• BCI Group Size: Dependent on engine type (e.g., Group 65 for gas, Group 31 for diesel where applicable, consult owner's manual)
• CCA Rating: 850-1000 CCA per battery (diesel models often have two batteries)
• Reserve Capacity: 150-190 minutes
• AGM vs. Flooded: Gas models typically use flooded lead-acid. Diesel models may benefit from AGM, but flooded is standard. Always consult owner's manual.
• Terminal Layout: Top Post
• Physical Dimensions: Varies by group size. Group 65: Approximately 12.06" L x 7.44" W x 7.56" H. Group 31: Approximately 13.00" L x 6.81" W x 9.44" H.
• Dual-Battery Setup: Standard on diesel engine models.

Replacement Battery Options

AGM vs. Flooded — Which Does This Vehicle Need?

For the 2024 Ford F-350 Super Duty, the choice between AGM (Absorbent Glass Mat) and flooded lead-acid batteries largely depends on your engine type and usage. Gas-powered F-350 models typically come equipped with and are well-served by conventional flooded lead-acid batteries. These are a cost-effective and reliable option for standard use.

Diesel-powered F-350s, which rely on two batteries for the substantial starting power required by their high-compression engines, can benefit significantly from AGM batteries. While many diesel F-350s come standard with flooded batteries, an upgrade to AGM can offer several advantages:

• Improved Durability: AGM batteries are more resistant to vibration and impacts, which is beneficial for heavy-duty trucks that often operate in demanding conditions.
• Longer Lifespan: AGMs generally have a longer service life than flooded batteries, potentially saving you money in the long run.
• Better Cold Weather Performance: They tend to perform more consistently in extreme cold, which is crucial for diesel engines, especially during winter months.
• Maintenance-Free: AGM batteries are sealed and do not require watering, making them truly maintenance-free.
• Deep Cycle Capability: If your F-350 has significant accessory loads or frequently sits with the engine off, AGM batteries handle deep discharges better.

Ultimately, while flooded batteries are perfectly adequate for most gas F-350 owners and many diesel owners, those seeking enhanced performance, durability, and a longer lifespan, especially in harsh conditions or with heavy electrical demands, should consider AGM replacements for their diesel F-350.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2024 Ford F-350 Super Duty, it's often necessary to perform a battery monitoring system (BMS) reset to ensure proper charging and prevent potential issues. The F-350 utilizes a smart charging system that learns the battery's state of charge and age. Without a reset, the vehicle's charging system might continue to charge the new battery based on the parameters of the old, degraded one.

Here's a common procedure for resetting the Battery Monitoring System (BMS) in many late-model Ford trucks. Please note that exact steps can vary slightly, so always consult your owner's manual for the most accurate information:

1. Ensure all accessories are off. Close all doors and turn off the ignition.
2. Disconnect the negative battery terminal for at least 15 minutes. This allows the vehicle's modules to power down and clear their volatile memory.
3. Reconnect the negative battery terminal. Make sure it's secure.
4. Turn the ignition to the "ON" position (without starting the engine) for at least 15-30 seconds. This allows the vehicle to recognize the new battery's presence.
5. Start the engine. Let the engine idle for a few minutes.
6. Drive the vehicle for at least 10 minutes at speeds above 40 mph. This helps the BMS system learn the new battery's characteristics.

Some F-350 models might also allow a BMS reset through the instrument cluster
