The 2020 Ford Explorer uses a 12-volt auxiliary battery. In most models equipped with Start-Stop, Ford specifies an AGM (Absorbent Glass Mat) 12-volt battery; the Explorer Hybrid adds a separate high-voltage battery pack for propulsion in addition to the 12-volt system.
Understanding exactly which battery your specific Explorer uses depends on the drivetrain and trim. This article breaks down the typical 12-volt battery types for non-hybrid and hybrid Explorers, how to identify which one you have, and what to consider when replacing or maintaining them.
Battery types and configurations
Different drivetrains affect which 12-volt battery is installed and how the vehicle’s electronics are managed. The following are the most common setups you’ll encounter in the 2020 Explorer lineup.
- 12-volt AGM battery (most common on Explorers with Start-Stop)
- 12-volt flooded lead-acid battery (used on some trims or configurations without Start-Stop)
- High-voltage battery pack (Explorer Hybrid) for propulsion, separate from the 12-volt system
In short, the presence of Start-Stop usually signals an AGM 12-volt battery, while hybrids add a high-voltage pack in addition to the standard 12-volt battery.
How to tell which battery your 2020 Explorer uses
Identify the exact battery type for your vehicle by checking labeling, documentation, and vehicle features. Use these steps to confirm with confidence.
- Look under the hood for the battery label or sticker; AGM batteries are often marked as AGM or have Ford part numbers that indicate AGM construction.
- Check the owner’s manual or the battery specification in the vehicle’s documentation; it will state whether Start-Stop is equipped and the recommended 12-volt battery type.
- Inspect the vehicle for Start-Stop functionality (the system may shut off the engine at idle). If Start-Stop is present, your 12-volt battery is most likely AGM.
- If you’re unsure, use your Vehicle Identification Number (VIN) to confirm the exact battery specification with a Ford dealer or a parts retailer.
Knowing whether you have Start-Stop and whether you’re dealing with a Hybrid helps ensure you buy the correct battery. When in doubt, consult a Ford dealer or a qualified technician to verify the correct part for your VIN.
Maintenance and replacement considerations
When replacing the 12-volt battery on a 2020 Explorer, follow Ford’s recommended part type and capacity. AGM batteries require compatible charging profiles and, in some cases, a charger designed for AGM cells. If you own a hybrid, never confuse the 12-volt battery with the high-voltage propulsion battery—the latter requires certified safety procedures and specialized service.
Here are practical guidelines to keep in mind when replacing or maintaining the battery:
- Use the correct 12-volt battery type (AGM if Start-Stop is present; flooded if not specified otherwise) as per your VIN and trim.
- Verify the battery’s cold-cranking/CCA rating and reserve capacity aligns with Ford’s specifications for your model year and drivetrain.
- Have replacement or maintenance performed by a technician trained in handling 12-volt systems and, for hybrids, high-voltage systems.
Using the correct battery type and proper installation helps prevent Start-Stop misbehavior and ensures reliable operation of the Explorer’s electronics. When in doubt, refer to Ford’s replacement part suggestions for your exact vehicle.
Hybrid-specific considerations
For Explorer Hybrid models, the high-voltage battery pack powers the electric motor, while the 12-volt battery continues to support standard vehicle electronics and accessories. The high-voltage system requires special safety precautions and servicing by trained professionals.
High-voltage system safety
Do not attempt to service the high-voltage battery yourself. If you suspect issues with the hybrid battery or powertrain, contact a Ford-certified hybrid technician or authorized service center.
12-volt battery role in hybrids
The 12-volt battery in a hybrid still plays a crucial role in starting the vehicle’s electronics, diagnostics, and non-propulsion systems. Replacement should follow the hybrid’s guidelines to ensure compatibility with the hybrid control systems.
Summary
In the 2020 Ford Explorer lineup, the standard is a 12-volt auxiliary battery, with AGM construction on most models that include Start-Stop. The Hybrid variant adds a high-voltage battery pack for propulsion in addition to the 12-volt system. To replace or service the battery correctly, verify your VIN and drivetrain, consult the owner's manual or a Ford dealer, and, if you have a hybrid, rely on qualified technicians for high-voltage work. Understanding whether you have Start-Stop and whether you drive a non-hybrid or hybrid model will guide you to the right battery choice and maintenance approach.
