AGM vs flooded — which does this vehicle need?

For the 2016 Chevrolet Malibu, an AGM (Absorbent Glass Mat) battery is required. The ninth-generation Malibu (2016–present) is equipped with a start-stop system to improve fuel efficiency. This technology places a much higher demand on the battery, as it is responsible for restarting the engine dozens of times during a single drive. Standard flooded batteries are not designed for this type of deep-cycling and will fail prematurely. AGM batteries are engineered to handle the frequent, high-current demands of start-stop systems, making them the only suitable choice.

Post-installation relearn / reset procedure

After replacing the battery in a 2016 Malibu, a relearn procedure is necessary to ensure the Battery Sensor Module (BSM) and Body Control Module (BCM) have accurate data about the new battery's state of charge and health. This helps the vehicle's charging system work efficiently and prolongs the life of the new battery.

While some systems may relearn on their own over several hours of driving, the official procedure is as follows:

1. Let the vehicle sit for at least 3 hours with the ignition off.
2. Start the engine.
3. Allow the engine to idle for at least 3 minutes.
4. The BCM will learn the new battery's characteristics. During this time, you might notice the voltmeter on the dash fluctuating more than usual—this is normal.

It is also recommended to reset the vehicle's various electronic modules. The simplest way to do this is to touch the positive and negative battery cables together for about 60 seconds before connecting them to the new battery. This will drain any residual power from the vehicle's capacitors and reset all modules to their default settings. You may need to reset your radio presets and clock after this procedure.

Signs of a failing battery

• Slow engine crank: The engine turns over sluggishly, especially on cold mornings.
• Start-stop system malfunction: The start-stop system may become disabled, and a message may appear on the dash.
• Dimming lights: Headlights and interior lights may dim, especially at idle or when using accessories like the power windows.
• Warning lights: A battery or charging system warning light may illuminate on the dashboard.
• Electrical gremlins: Unexplained issues with the radio, infotainment system, or other electronics can be a sign of an unstable power supply from a failing battery.

Common battery issues for this generation

The 2016 Malibu's reliance on a sophisticated electrical system and start-stop technology means it is more sensitive to battery health than older vehicles. The most common issue is premature battery failure caused by either using an incorrect (flooded) battery or a faulty BSM. If the BSM is not accurately monitoring the battery's state of charge, it can lead to under- or over-charging, both of which will significantly shorten the battery's lifespan.
