AGM vs Flooded — Which Does This Vehicle Need?

The 2020 Chevrolet Equinox, especially models equipped with the automatic engine Start/Stop system, is best served by an Absorbent Glass Mat (AGM) battery. The frequent engine stops and starts place a higher demand on the battery, requiring it to cycle more deeply and recover faster than a traditional flooded lead-acid battery. AGM batteries are designed to handle these cycling demands much more effectively, offering longer lifespan and better performance in Start/Stop applications.

While a high-quality flooded battery may work in an Equinox without Start/Stop technology or if the Start/Stop feature is always disabled, it's generally recommended to stick with an AGM battery if that's what came from the factory. Using a flooded battery in a vehicle designed for AGM could lead to premature battery failure and potential issues with the vehicle's electrical system.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2020 Chevrolet Equinox, it's important to perform a battery relearn procedure. This helps the vehicle's computer (BCM - Body Control Module) optimize charging based on the new battery's characteristics, ensuring proper charging and preventing premature battery failure. While the exact procedure can vary slightly, a common method involves:

1. Ensuring all accessories are off: Before connecting the new battery, make sure the ignition is off, and all interior and exterior lights, radio, and other accessories are off.
2. Connecting the new battery: Connect the positive terminal first, then the negative terminal. Ensure connections are clean and tight.
3. Allowing the vehicle to 'sleep': After connecting, leave the vehicle completely off and undisturbed for several minutes (e.g., 10-15 minutes). This allows some modules to power down and reset.
4. Idle Relearn (Optional but recommended): Some vehicles benefit from an idle relearn. Start the engine and let it idle in Park for at least 5-10 minutes without touching the accelerator or any vehicle controls. This allows the engine control module to re-learn idle parameters.
5. Window Express Up/Down Reset: You may need to reset the power window's express up/down feature. To do this, roll the window all the way down, then hold the button up until the window is fully closed and continue to hold for an additional 2-3 seconds.
6. Radio/Clock Settings: You'll likely need to re-enter your radio presets and reset the clock.

For the most accurate and specific procedure, consult your 2020 Chevrolet Equinox owner's manual or a certified Chevrolet technician. Some professional scan tools can also perform a dedicated battery registration/relearn.
