Let’s get your tools ready and dive into the engine bay.
Understanding Your 2020 Ford Explorer’s Power Needs
The 2020 model year marked a significant redesign for the Ford Explorer, moving back to a rear-wheel-drive biased platform. This change also influenced the electrical architecture. Most 2020 Explorers come equipped with an AGM battery from the factory, which is designed to handle the heavy cycling of the Auto Start-Stop system.
Unlike traditional flooded lead-acid batteries, AGM variants are spill-proof and have a much higher resistance to vibration. This is particularly important if you take your Explorer off-road or live in a climate with extreme temperature swings. When selecting a replacement, never “downgrade” to a standard battery, as it will likely fail within months under the high-demand charging profile of this vehicle.
You will typically need a Group Size 48 (H6) or Group Size 94R (H7) battery, depending on your specific engine and trim level. Always check the label on your existing battery or consult your owner’s manual to verify the Cold Cranking Amps (CCA) rating. A higher CCA rating is generally better if you live in a northern climate where sub-zero mornings are common.
Signs You Need a 2020 ford explorer battery replacement
Batteries rarely fail without giving off a few warning signals first. One of the most common signs is a “lazy” or slow engine crank. If the engine takes longer than usual to fire up, the lead plates inside the battery are likely sulfated, meaning they can no longer hold a full charge.
Another telltale sign is the behavior of your interior electronics. You might notice the SYNC 3 infotainment screen flickering, or your power liftgate moving slower than usual. Modern Fords are designed to shut down non-essential systems to save power for the starter, so if your heated seats or Auto Start-Stop stop working, the car is trying to tell you something.
Finally, look for physical clues under the hood. If you see white, powdery terminal corrosion or a bloated battery case, the unit is end-of-life. Ignoring these signs can lead to a stranded vehicle or, worse, damage to your alternator as it overworks itself to compensate for a dying cell. A proactive 2020 ford explorer battery replacement is much cheaper than a midnight tow truck.
Essential Tools and Safety Gear
Before you pop the hood, gather the necessary tools to ensure the job goes smoothly. You do not need a massive rolling chest for this. A basic mechanic’s tool set will cover 90% of what is required for this specific vehicle layout.
- 10mm Socket or Wrench: This is the most important tool, used for the terminal clamps and the battery hold-down bracket.
- Socket Extension: A 6-inch extension helps you reach the hold-down bolt at the base of the battery tray.
- Battery Terminal Brush: Use this to clean the cable ends to ensure a perfect electrical connection.
- Safety Glasses and Gloves: Even sealed AGM batteries contain acid; protect your eyes and skin from accidental contact or sparks.
- Memory Saver (Optional): This plugs into your OBD-II port to keep your radio presets and clock settings active while the battery is disconnected.
Safety is paramount when working around automotive electricity. Always remove any metal jewelry, such as rings or watches, which could cause a short circuit if they touch the positive terminal and the vehicle chassis simultaneously. Ensure you are working in a well-ventilated area, away from open flames or smoking materials.
Step-by-Step Guide to 2020 ford explorer battery replacement
In the 2020 Explorer, the battery is located in the engine compartment on the passenger side, near the firewall. It is often tucked under a plastic cowl or cover that helps protect it from engine heat. Follow these steps carefully to ensure a successful 2020 ford explorer battery replacement without damaging any sensitive sensors.
Step 1: Accessing the Battery
Open the hood and locate the battery cover on the passenger side. There are usually a few plastic clips or “push pins” holding the weatherstripping or the cover itself in place. Gently pry these up using a flathead screwdriver or a trim removal tool. Set the cover aside where it won’t get stepped on.
Step 2: Disconnecting the Negative Terminal
Always disconnect the negative (black) terminal first. Use your 10mm wrench to loosen the nut on the clamp. You don’t need to remove the nut entirely; just loosen it enough to wiggle the clamp off the post. Tuck the cable to the side so it cannot accidentally spring back and touch the terminal.
Step 3: Disconnecting the Positive Terminal
Now, lift the red plastic protective cap and loosen the positive (red) terminal. Be very careful not to let your wrench touch any metal part of the car while you are in contact with the positive post. This would create a “dead short” and could blow expensive fuses or damage the Body Control Module.
Step 4: Removing the Hold-Down Bracket
At the base of the battery, you will see a small metal or plastic wedge held down by a long bolt. Use your 10mm socket and extension to remove this bolt. Once the bracket is out, the battery is free to be lifted. Be prepared; these batteries weigh between 40 and 50 pounds, so use proper lifting form to avoid back strain.
Step 5: Cleaning and Preparation
Before dropping the new battery in, take a moment to inspect the battery tray. If there is debris or leaves, vacuum them out. Use your terminal brush to scrub the inside of the cable clamps until the metal is shiny. A clean connection prevents voltage drops and ensures the alternator can charge the new battery efficiently.
Step 6: Installing the New Battery
Lower the new battery into the tray, ensuring the positive and negative posts are oriented exactly like the old one. Reinstall the hold-down bracket and tighten the bolt until the battery is snug and cannot be moved by hand. Connect the positive terminal first, followed by the negative terminal. Tighten the nuts until the clamps are firm, but do not over-tighten and strip the threads.
The Battery Management System (BMS) Reset
One of the most critical aspects of a 2020 ford explorer battery replacement is the BMS reset. Your Explorer has an intelligent sensor on the negative terminal that tracks the age and health of the battery. Over time, the computer changes the alternator’s charging strategy to account for a weakening battery.
If you install a brand-new battery but don’t reset the BMS, the car will continue to charge the new battery as if it were an old, dying one. This can lead to undercharging, shortened battery life, and issues with the Auto Start-Stop system. While a professional scan tool is the best way to do this, there is a manual “handshake” method that often works for Fords.
To perform a manual reset: Turn the ignition to the “On” position (engine off). Flash your high beams five times, then press and release the brake pedal three times. If done correctly, the battery icon on the dashboard should flash after a few seconds, indicating the system has recognized the new power source. If this doesn’t work, any local mechanic with a basic OBD-II scanner can perform the reset in about two minutes.
Maintenance Tips for Longevity
Once you have completed your 2020 ford explorer battery replacement, you want that investment to last as long as possible. The average lifespan of an AGM battery is 4 to 6 years, but poor habits can cut that in half. One of the best things you can do is avoid short trips where the alternator doesn’t have enough time to replenish the energy used during the start-up.
If you use your Explorer for overlanding or camping and have accessories like a fridge or extra lights, consider a portable jump starter or a solar maintainer. These tools ensure that even if you drain the battery while parked, you aren’t left stranded in the wilderness. Additionally, checking the terminal tightness during every oil change is a pro-level habit that prevents intermittent electrical gremlins.
Keep the top of the battery clean and dry. Dirt and moisture can actually create a very slight electrical path between the terminals, leading to a “parasitic drain.” A quick wipe with a microfiber cloth every few months is all it takes to keep the electrostatic discharge at bay and your electrical system healthy.
Frequently Asked Questions About 2020 ford explorer battery replacement
How much does a 2020 ford explorer battery replacement cost?
Expect to pay between $200 and $300 for a high-quality AGM battery. If you have the work done at a dealership, the total bill including labor and the BMS reset can range from $400 to $550. Doing it yourself saves you the labor fee and the markup on the part.
Can I use a regular lead-acid battery instead of an AGM?
It is strongly discouraged. The 2020 Explorer is designed for the faster charging rates and deeper discharge cycles of an AGM battery. Using a standard flooded battery will likely cause the Auto Start-Stop system to fail and will lead to a much shorter battery lifespan.
What happens if I don’t reset the BMS?
If the BMS isn’t reset, the alternator will continue to use an “aged” charging profile. This typically results in the new battery not receiving a full charge, which can cause it to fail prematurely. You may also notice that your fuel-saving Auto Start-Stop feature remains disabled indefinitely.
Where is the battery located on the 2020 Explorer Hybrid?
While the standard 2020 Explorer has the 12V battery in the engine bay, some hybrid configurations may have different access points or auxiliary batteries. Always consult your specific VIN-based manual if you have the Hybrid or Platinum trims to confirm the primary 12V battery location.
Final Thoughts on Your DIY Success
Completing a 2020 ford explorer battery replacement is a badge of honor for any DIY owner. It proves that you can maintain your own vehicle and understand the complex systems that keep it running. By choosing the right AGM battery and ensuring the BMS is reset, you have done a better job than many “express” service centers would.
Remember to dispose of your old battery responsibly. Almost every auto parts store will take your old unit and even give you a “core charge” refund, which usually puts $15 to $22 back in your pocket. This recycling process is essential for keeping lead and acid out of our landfills.
Stay safe, keep your terminals clean, and enjoy the peace of mind that comes with a strong, reliable start every time you turn the key. Whether you are heading to the grocery store or a remote trailhead, your Explorer is now ready for the journey ahead. Happy wrenching!
