AGM vs flooded — which does this vehicle need?
The 2019 GMC Acadia requires an Absorbent Glass Mat (AGM) battery. This is because the Acadia is equipped with an engine start/stop system, which puts a higher demand on the battery. AGM batteries are better suited to handle the frequent starts and stops of this system, and they also have a longer lifespan than traditional flooded batteries.
Post-installation relearn / reset procedure
After replacing the battery in your 2019 GMC Acadia, you will need to perform a battery relearn procedure. This procedure allows the vehicle's computer to learn the new battery's state of charge and adjust the charging system accordingly. To perform the relearn procedure, you will need a scan tool that is capable of performing this function. The procedure may vary depending on the scan tool you are using, so it is important to follow the instructions that come with your scan tool.
Signs of a failing battery
There are several signs that your 2019 GMC Acadia's battery may be failing. These include:
- The engine is slow to crank
- The headlights are dim
- The battery is leaking or has corrosion on the terminals
- The battery is more than 3-5 years old
If you are experiencing any of these symptoms, it is a good idea to have your battery tested by a qualified technician.
Common battery issues for this generation
The most common battery issue for the 2019 GMC Acadia is premature battery failure. This is due to the high demands of the engine start/stop system. To help prevent premature battery failure, it is important to use a high-quality AGM battery and to have the battery tested regularly.
Another common issue is a loose or corroded battery terminal. This can cause a variety of problems, including a no-start condition. To prevent this, it is important to check the battery terminals regularly and to clean them if necessary.
