AGM vs flooded — which does this vehicle need?

The 2020 Ford F-250 Super Duty comes from the factory with an AGM battery. It's crucial to replace it with another AGM for several reasons. Modern vehicles, especially those with high electrical demands like the F-250, rely on the stable power and vibration resistance that AGM batteries provide. Features like auto start-stop, extensive infotainment systems, and numerous onboard computers require a battery that can handle deep cycling and frequent recharging. A traditional flooded battery will not be able to keep up and will likely fail prematurely.

Post-installation relearn / reset procedure

After replacing the battery in your 2020 F-250, you'll need to perform a Battery Monitoring System (BMS) reset. This procedure tells the vehicle's computer that a new battery has been installed, allowing it to adjust the charging strategy for optimal performance and battery life.

To reset the BMS:

1. Turn the ignition on (without starting the engine).
2. Pull and release the high beam lever five times.
3. Press and release the brake pedal three times.
4. The battery light on the dashboard should flash, indicating the reset was successful.

Signs of a failing battery

• Slow Engine Crank: The engine struggles to turn over, especially in cold weather.
• Warning Lights: A battery or check engine light may illuminate on the dashboard.
• Dimming Lights: Headlights and interior lights may dim, particularly at idle.
• Electrical Issues: Malfunctions with the radio, power windows, or other electronics.
• Visible Corrosion: A white, powdery substance around the battery terminals.

Common battery issues for this generation

The 2017-2022 generation of Ford Super Duty trucks has a sophisticated electrical system that can be sensitive to battery health. The most common issue is a parasitic drain, where a component continues to draw power after the truck is turned off. This can be caused by aftermarket accessories or a faulty module. If your battery repeatedly dies, a parasitic drain test should be performed by a qualified technician.
