AGM vs flooded — which does this vehicle need?
An AGM battery is required. The 2022 Chevrolet Tahoe is equipped with a start-stop system, which is hard on a traditional flooded battery. An AGM (Absorbent Glass Mat) battery is designed to handle the frequent, deep discharges that are a normal part of a start-stop system's operation. Use of a flooded battery will result in a short service life and can damage the vehicle's charging system.
Post-installation relearn / reset procedure
After replacing the battery, you will need to perform a battery relearn procedure. This can be done with a professional scan tool. The procedure will reset the battery monitoring system and ensure that the new battery is charged correctly.
Signs of a failing battery
- Slow engine crank
- Dimming headlights at idle
- "Service Battery" or "Check Charging System" message on the dash
- Corrosion on the battery terminals
Common battery issues for this generation
This generation of Tahoe is known for a parasitic draw on the battery. This can be caused by a number of things, including a faulty module or a software issue. If you are experiencing a dead battery after the vehicle has been sitting for a few days, you may have a parasitic draw.
