AGM vs. Flooded — Which Does This Vehicle Need?

The 2022 Ford Explorer, especially models equipped with Start-Stop technology, requires an Absorbent Glass Mat (AGM) battery. While a traditional flooded lead-acid battery might fit physically, it is not designed to handle the frequent discharge and recharge cycles inherent in Start-Stop systems. Using a flooded battery in a vehicle designed for AGM can lead to significantly reduced battery life, premature failure, and potentially affect the proper operation of the Start-Stop system and other electrical components.

AGM batteries are more robust, offer higher reserve capacity, and can withstand deeper discharge cycles without damage. Their sealed design also makes them maintenance-free and resistant to vibration. Always confirm your vehicle's specific battery type recommendation, but for the 2022 Explorer, AGM is the correct choice.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2022 Ford Explorer, it's crucial to perform a battery monitoring system (BMS) reset, especially if your vehicle has Start-Stop technology. This procedure informs the vehicle's computer (PCM) that a new battery has been installed, allowing it to correctly monitor battery health, optimize charging, and ensure proper function of the Start-Stop system.

While specific steps can vary, a common manual reset procedure involves:

1. Turn the ignition ON (engine OFF).
2. Turn on the headlights for at least 20 seconds.
3. Turn the headlights OFF.
4. Turn the ignition OFF.

Alternatively, many professional scan tools can perform a BMS reset. If you don't have access to a scan tool or the manual procedure doesn't seem to work, it's best to have a qualified technician perform the reset. Failure to reset the BMS can lead to reduced battery life, inconsistent Start-Stop operation, and potentially other electrical system quirks.

Signs of a Failing Battery

Recognizing the signs of a failing battery can save you from being stranded. For your 2022 Ford Explorer, keep an eye out for these common indicators:

• Slow Cranking: The engine turns over sluggishly when you try to start the vehicle.
• Dim Headlights/Interior Lights: Lights appear dim, especially when the engine is off or starting.
• Warning Lights: A battery warning light or "Service AdvanceTrac" message on the dashboard.
• Electrical 시스템 Glitches: Erratic behavior from power windows, radio, or other electronic components.
• Corrosion on Terminals: White or blue powdery substance around the battery terminals.
• Swelling or Bulging Battery Case: A sign of internal damage or overcharging.
• Foul Odor: A smell similar to rotten eggs emanating from the battery, indicating acid leakage or sulfation.
• Start-Stop System Malfunctions: The Start-Stop system not engaging as frequently or failing to work altogether.

Common Battery Issues for This Generation

For the 2022 Ford Explorer, common battery issues often revolve around the demands of modern vehicle electronics and Start-Stop technology:

• Premature Failure with Incorrect Battery Type: As mentioned, using a flooded battery instead of an AGM in a Start-Stop equipped Explorer will significantly shorten its lifespan.
• Parasitic Draws: Modern vehicles have numerous modules that draw small amounts of power even when the vehicle is off. If one of these modules malfunctions, it can create an excessive parasitic draw, draining the battery prematurely.
• BMS Issues: A improperly reset or malfunctioning battery monitoring system can lead to incorrect charging strategies, either overcharging or undercharging the battery, both of which reduce battery life.
• Short Trip Driving: Frequent short trips (less than 20 minutes) may not allow the alternator to fully recharge the battery, especially with the added load of infotainment and Start-Stop cycles.
• Extreme Temperatures: Both very cold and very hot temperatures can stress batteries, reducing their overall lifespan.

Maintain your battery's health by ensuring it's the correct AGM type, performing the BMS reset after replacement, and addressing any electrical issues promptly.
