AGM vs flooded — which does this vehicle need?
The 2017 GMC Sierra 1500 requires an Absorbent Glass Mat (AGM) battery. This is because the Sierra 1500 is equipped with a start-stop system, which puts a greater demand on the battery. AGM batteries are better suited to handle the frequent starting and stopping of the engine, as they have a higher reserve capacity and can be discharged and recharged more times than a traditional flooded battery.
Post-installation relearn / reset procedure
After replacing the battery in your 2017 GMC Sierra 1500, you may need to perform a relearn/reset procedure. This is to ensure that the vehicle's computer system recognizes the new battery and adjusts its charging strategy accordingly. The relearn procedure can be performed with a scan tool, or by following these steps:
- Turn the ignition to the "ON" position, but do not start the engine.
- Press and hold the "Home" and "Back" buttons on the steering wheel for 5 seconds.
- The "Battery" icon will appear on the driver information center (DIC).
- Press the "Up" or "Down" arrow button to scroll to the "Battery Voltage" screen.
- Press and hold the "Enter" button for 5 seconds.
- The DIC will display a message confirming that the battery relearn procedure has been completed.
