AGM vs flooded — which does this vehicle need?

The 2017 Ford F-250 Super Duty requires an Absorbent Glass Mat (AGM) battery. This is due to the advanced electronics and start-stop technology featured in this generation of trucks. AGM batteries offer superior performance and are better equipped to handle the high electrical demands of modern vehicles. They are also more resistant to vibration and are non-spillable, making them a safer and more durable option.

Post-installation relearn / reset procedure

After replacing the battery in your 2017 F-250, a battery relearn procedure is necessary. This allows the vehicle's computer to recognize the new battery and adjust the charging system accordingly. The process typically involves a series of steps that can be performed without special tools, although a diagnostic scan tool can also be used. A common method involves turning the headlights on and off, pressing the brake pedal multiple times, and allowing the vehicle to idle for a specific period. Consult your owner's manual for the exact procedure for your truck.

Signs of a failing battery

• Slow engine crank: The engine takes longer than usual to start.
• Dimming lights: Headlights and interior lights may dim, especially during startup.
• Warning lights: The battery or check engine light may illuminate on the dashboard.
• 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

While the 2017 F-250 is a robust truck, some owners have reported premature battery failure. This can be attributed to the high electrical demands of the vehicle, especially in models equipped with numerous accessories. To maximize battery life, ensure all connections are clean and tight, and consider using a battery tender if the truck is not driven regularly.
