Signs Your 2016 Ford Explorer Needs a New Battery
Before you start the 2016 ford explorer battery replacement, you should confirm that the battery is actually the culprit. Modern electronics in the Explorer can be sensitive to voltage drops, leading to strange dashboard behavior. If your interior lights flicker or your power liftgate moves slowly, your battery might be nearing the end of its life.
Cold weather is the ultimate test for any automotive power cell. If your engine cranks slowly on chilly mornings, the chemical reaction inside the battery is likely failing. You might also notice a “Battery Saver Active” message on your infotainment screen, which is a clear sign the system is shedding loads to preserve power.
Physical inspection can also reveal hidden issues. Look for a bloated battery case, which suggests overcharging or extreme heat exposure. If you see white, crusty powder around the terminals, that is acid corrosion, which increases electrical resistance and prevents proper charging.
Essential Tools and Materials for the Job
You do not need a professional shop to handle this task, but having the right tools makes the job safer and faster. The 2016 Explorer typically uses a 10mm nut for the terminal clamps, which is standard for most Ford vehicles. A socket set with an extension is often better than a flat wrench for reaching the hold-down bracket.
- 10mm deep-well socket and ratchet.
- 8mm socket (for some hold-down bolts).
- Battery terminal cleaning brush.
- Safety glasses and work gloves.
- Baking soda and water solution (to neutralize acid).
- Dielectric grease or terminal protector spray.
- A memory saver (optional but recommended).
Using a memory saver is a pro tip that prevents your radio presets and engine trim values from being wiped. This tool plugs into your OBD-II port and provides a tiny amount of power while the main battery is disconnected. It is not strictly necessary, but it saves you the hassle of resetting your clock and seat positions.
Safety First: Working with Automotive Electricity
Batteries contain sulfuric acid and can produce explosive hydrogen gas during the charging process. Always work in a well-ventilated area and keep sparks or open flames away from the engine bay. Wearing eye protection is mandatory, as even a small drop of acid can cause permanent damage.
The golden rule of battery work is the order of disconnection. Always disconnect the negative (black) cable first. This prevents an accidental short circuit if your wrench touches the metal frame of the car while loosening the positive terminal. If you touch the frame while working on the positive side first, you will create a massive spark.
Once the old battery is out, handle it with care. It is heavy, often weighing between 40 and 50 pounds. Use the built-in handle if available, and keep the battery upright to prevent leaks. Remember that lead-acid batteries are highly recyclable, so plan to drop your old one off at a local auto parts store.
Step-by-Step 2016 ford explorer battery replacement
Now that you have your tools and safety gear, it is time to begin the actual 2016 ford explorer battery replacement. Start by parking the vehicle on a level surface and engaging the parking brake. Pop the hood and locate the battery on the driver’s side of the engine compartment, usually tucked near the firewall.
Step 1: Removing the Old Battery
Loosen the nut on the negative terminal clamp using your 10mm socket. Wiggle the cable free and tuck it to the side so it cannot accidentally touch the post. Repeat this process for the positive (red) terminal, ensuring you do not let your tools bridge the gap between the two posts.
Next, locate the battery hold-down bracket. This is usually a strap or a block at the base of the battery held by a long bolt. Remove the bolt entirely and set the bracket aside. Carefully lift the battery out of the tray, being mindful of its weight and any surrounding plastic shrouds.
Step 2: Cleaning the Battery Tray and Terminals
Before installing the new unit, take a moment to clean the area. If there is corrosion on the cable ends, dip them in a mixture of baking soda and water. Use a wire brush to scrub the inside of the clamps until the metal is shiny, which ensures a perfect electrical connection.
Check the battery tray for debris or rocks that could puncture the new battery casing. If the tray is metal and shows signs of rust, you can spray it with a bit of rust-inhibitor paint. A clean environment helps the new battery sit level and stay secure during off-road adventures or bumpy commutes.
Step 3: Installing the New Battery
Lower the new battery into the tray, making sure the positive and negative posts are oriented correctly. Reinstall the hold-down bracket and tighten the bolt until the battery does not move when shaken. A loose battery can suffer internal damage from engine vibrations.
Connect the positive cable first this time. Tighten the nut until the clamp is snug and cannot be rotated by hand. Finally, connect the negative cable. You may see a small spark when the negative terminal touches the post; this is normal as the vehicle’s computers wake up.
The Battery Management System (BMS) Reset
One of the most overlooked parts of a 2016 ford explorer battery replacement is the BMS reset. Your Explorer uses a sensor to track the age and health of the battery. As a battery gets older, the alternator changes the charging profile to compensate for internal wear.
If you do not reset this system, the computer will treat the brand-new battery like an old, failing one. This can lead to overcharging, which significantly shortens the life of your new investment. While a dealership can do this with a scan tool, there is a manual “secret” method for DIYers.
- Get in the vehicle and close all doors.
- Turn the ignition to the “On” position (engine off).
- Flash the high beams 5 times.
- Step on the brake pedal 3 times.
- Wait for the battery light on the dash to flash 3 times.
This sequence signals the computer that a new battery is present. If the light flashes, the reset was successful. This simple step ensures your alternator provides the optimal voltage for a fresh battery, protecting your electronics and your wallet.
Choosing the Right Battery for Your Explorer
When shopping for a 2016 ford explorer battery replacement, you will encounter different “Group Sizes.” Most 2016 Explorers require a Group 65 battery, but always check your owner’s manual or the label on your existing battery. Choosing the wrong size can mean the terminals won’t reach or the hold-down bracket won’t fit.
You also need to decide between a standard flooded lead-acid battery and an Absorbent Glass Mat (AGM) battery. AGM batteries are more expensive but offer better vibration resistance and faster charging. If you do a lot of off-roading or have installed heavy-duty winches and lights, the AGM is well worth the extra cost.
Pay attention to the Cold Cranking Amps (CCA) rating. This number indicates how much power the battery can deliver at zero degrees Fahrenheit. For a 2016 Explorer, you generally want a battery with at least 650 to 750 CCA, especially if you live in a northern climate where winters are harsh.
Troubleshooting Common Issues After Replacement
Sometimes, even after a successful 2016 ford explorer battery replacement, you might notice minor issues. The most common is a rough idle. This happens because the Engine Control Unit (ECU) lost its “learned” idle trim values. The car will eventually relearn these as you drive, usually within 10 to 20 miles.
If your power windows do not auto-up or auto-down correctly, they may need a simple re-homing procedure. Hold the window switch in the “up” position for a few seconds after the window closes, then repeat in the “down” position. This recalibrates the safety sensors for the glass.
If the vehicle refuses to start at all, double-check your terminal connections. Even a slightly loose clamp can prevent the high current needed for the starter motor. Ensure no plastic caps from the new battery were left on the posts before you attached the cables.
Frequently Asked Questions About 2016 Ford Explorer Battery Replacement
How long does a 2016 Ford Explorer battery typically last?
On average, an OEM battery lasts between 3 and 5 years. Factors like extreme heat, frequent short trips, and high electrical loads (like heated seats and infotainment) can reduce this lifespan. If you live in a very hot climate, expect to replace it closer to the 3-year mark.
Can I replace the battery without a scan tool?
Yes, you can physically replace the battery with basic hand tools. However, you must perform the manual BMS reset described earlier to ensure the charging system functions correctly. Without the reset, you risk damaging the new battery over time.
What happens if I don’t reset the BMS?
If the BMS is not reset, the alternator may continue to charge the new battery at a higher voltage intended for an aging unit. This can cause the battery to overheat, outgas, and fail prematurely. It may also disable features like “Auto Start-Stop” if your vehicle is equipped with it.
Is it safe to jump-start a 2016 Ford Explorer?
Yes, it is safe, but you should connect the negative jumper cable to a grounding point on the engine block rather than the negative terminal of the dead battery. This protects the BMS sensor located on the negative cable from power surges.
