2019 Ford F-150 Battery: Group Size, CCA & Replacement Guide

Quick Answer

• BCI Group Size: H6 (also called Group 48) is the most common size for the 2019 F-150. However, some models with higher electrical demands, like those with the 3.5L EcoBoost or 5.0L V8, may use a larger H7 (Group 94R) battery.
• Cold Cranking Amps (CCA): A minimum of 610 CCA is required, but 700-800 CCA is recommended for better performance, especially in colder climates.
• Reserve Capacity (RC): Look for a battery with at least 110 minutes of reserve capacity.
• AGM vs. Flooded: An AGM (Absorbent Glass Mat) battery is required for F-150s equipped with Auto Start-Stop technology. For models without this feature, a traditional flooded battery is acceptable, though an AGM is still a recommended upgrade for its durability and performance.
• Terminal Layout: Top post, with the positive terminal on the right (this is a standard "right-hand positive" layout).
• **Physical Dimensions (approximate):
  • H6/Group 48: 12.4" L x 6.9" W x 7.5" H
  • H7/Group 94R: 12.4" L x 6.9" W x 7.5" H
• Dual-Battery Setup: The 2019 F-150 with the 3.0L Power Stroke diesel engine features a dual-battery setup for increased starting power and to handle the demands of the diesel system.

AGM vs. Flooded — Which Does This Vehicle Need?

The 2019 Ford F-150 is equipped with a Battery Management System (BMS) that monitors the battery's state of charge and health. For models with Auto Start-Stop, an AGM battery is mandatory. The frequent engine starts and stops put a high demand on the battery, and AGM technology is designed to handle this deep cycling better than a conventional flooded battery. Using a flooded battery in an F-150 with Auto Start-Stop will lead to premature battery failure and may cause issues with the vehicle's electrical system.

For F-150s without Auto Start-Stop, a standard flooded battery will work. However, upgrading to an AGM is highly recommended. AGMs offer better vibration resistance, are spill-proof, and generally have a longer service life. Given the increasing electrical demands of modern vehicles, an AGM is a worthwhile investment for improved reliability.

Post-Installation Relearn / Reset Procedure

After replacing the battery in a 2019 F-150, the Battery Management System (BMS) must be reset. This tells the vehicle that a new battery has been installed and allows the system to adjust its charging strategy accordingly. If this reset is not performed, the BMS may continue to charge the new battery as if it were an old, degraded one, which can shorten the new battery's life.

The reset procedure typically requires a scan tool with BMS reset capabilities. While some online forums suggest a "key-on, headlight flash" sequence, the most reliable method is to use a proper diagnostic tool. Many auto parts stores and all professional repair shops will have the necessary equipment to perform this reset.

Signs of a Failing Battery

• Slow Engine Crank: The engine turns over sluggishly when you try to start it.
• Dimming Lights: Headlights and interior lights may dim, especially at idle or when starting the engine.
• Warning Lights: A battery or check engine light may appear on the dashboard.
• Clicking Sound: A rapid clicking noise when turning the key indicates the starter is not getting enough power.
• Swollen Battery Case: If the battery case looks bloated or misshapen, it's a sign of internal damage and the battery should be replaced immediately.

Common Battery Issues for This Generation

The 2013-2020 generation of F-150s has a known issue with "parasitic drain," where certain modules in the vehicle may not go to "sleep" properly after the ignition is turned off, leading to a slow drain on the battery. If you find your battery is frequently dead, even after being replaced, a parasitic draw test should be performed by a qualified technician to identify the source of the problem.
