AGM vs. flooded — which does this vehicle need?

Your 2022 Ford F-350 Super Duty comes from the factory with a standard flooded lead-acid battery for gasoline models and two flooded lead-acid batteries for diesel models. While these are perfectly adequate for normal operation, an Absorbed Glass Mat (AGM) battery is a significant upgrade that offers several advantages:

• Durability: AGM batteries are more resistant to vibration and impacts, which is beneficial for a heavy-duty truck that might see rough roads or towing.
• Deeper Discharge Cycles: They can withstand deeper discharge cycles without damage, making them ideal if you regularly use accessories with the engine off (like a fridge, inverter, or extensive stereo system).
• Slower Self-Discharge: AGM batteries hold their charge longer when the vehicle is not in use.
• Maintenance-Free: They are sealed and do not require water top-offs.
• Improved Performance: Often offer higher CCA and better cold-weather performance.

For the F-350, especially diesel models with their high electrical demands, upgrading to AGM is highly recommended for improved reliability and longevity.

Post-installation relearn / reset procedure

After disconnecting and replacing the battery in your 2022 Ford F-350 Super Duty, it's crucial to perform a Battery Monitoring System (BMS) reset. This procedure allows the vehicle's computer to properly recalibrate and monitor the new battery's state of charge and health. Failing to do so can lead to improper charging, premature battery failure, and issues with vehicle accessories.

BMS Reset Procedure:

1. Ensure all accessories are off: Turn off the radio, lights, climate control, and any other electrical accessories.
2. Close all doors and hood: Make sure the vehicle is completely shut down.
3. Connect the new battery: Securely install the new battery (or batteries for diesel models).
4. Wait: Allow the vehicle to sit undisturbed for at least 8 hours (some suggest 12 hours) to allow all modules to power down and reset.
5. Start the vehicle: After the waiting period, start the F-350.
6. Perform the headlight flash method (optional but recommended): With the engine running, turn on the headlights to high beam for 20-30 seconds. Then turn them off. Repeat this process 3-5 times. This helps signal the BMS to re-evaluate the battery.
7. Drive cycle: Drive the vehicle for at least 15-20 minutes, allowing the charging system to fully engage and the BMS to learn the new battery parameters.

Some advanced scan tools can also perform a direct BMS reset. If you have access to one, it's the most precise method.

Signs of a failing battery

Don't wait until your F-350 leaves you stranded. Watch out for these common signs of a weakening battery:

• Slow cranking: The engine cranks slower than usual when starting, especially in cold weather.
• Dim headlights/interior lights: When the engine is off but accessories are on, lights appear dim.
• Check Engine Light / Battery Light: These dashboard warnings can indicate charging system or battery issues.
• Corrosion on terminals: Excessive white or green powdery corrosion around the battery terminals.
• Swollen or bulging battery case: A sign of internal damage or overcharging.
• Foul smell: A rotten egg smell indicates a leaking battery or overcharging.
• Electrical glitches: Issues with power windows, radio, or other electronic components.
• Age: Most batteries last 3-5 years. If yours is older, it's nearing the end of its life.

Common battery issues for this generation

While the 2022 F-350 is a robust truck, certain battery-related issues can arise:

• High electrical demand: Modern heavy-duty trucks have numerous electronic systems, leading to high parasitic draws that can strain a battery, especially if the vehicle sits for extended periods.
• Cold weather performance: Like all batteries, extreme cold can significantly reduce capacity and CCA, making starting difficult, particularly for diesel engines with their higher compression.
• Accessory drain: Using accessories like a large inverter, aftermarket lights, or leaving the ignition on for extended periods without the engine running can quickly drain the battery.
• Alternator issues: A failing alternator can undercharge or overcharge the battery, leading to premature failure.
• Corrosion: Ford trucks often experience corrosion around battery terminals if not properly maintained, impacting connections and charging.
