Replacement Battery Options

Finding the right battery for your 2017 Ford Explorer is crucial for reliable starting and powering all your vehicle's electronics. Here are some popular replacement options:

• Interstate: MTX-48/H6 (AGM), MTP-48/H6 (Flooded)
• Optima: DH6 YellowTop (AGM)
• DieHard: Platinum AGM H6 (AGM)
• Odyssey: ODP-AGM48 H6 (AGM)
• ACDelco: 48AGMHR (AGM)

AGM vs. Flooded — Which Does This Vehicle Need?

The 2017 Ford Explorer, especially models equipped with start-stop technology, is designed to utilize an Absorbent Glass Mat (AGM) battery. While a traditional flooded lead-acid battery may work, it's generally not recommended for optimal performance and longevity, particularly if your Explorer has the start-stop system.

AGM batteries are superior for several reasons:

• Durability: They are more resistant to vibrations and impacts.
• Charge Acceptance: They recharge faster, which is beneficial for vehicles with start-stop technology that frequently cycle the battery.
• Deep Cycling: They can withstand deeper discharge cycles without significant damage.
• Maintenance-Free: They are sealed and require no water additions.

If your Explorer does not have start-stop technology, a high-quality flooded battery can still be a viable, more economical option. However, even without start-stop, an AGM battery will generally provide better performance and a longer lifespan.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2017 Ford Explorer, it's important to perform a battery monitoring system (BMS) reset. This tells the vehicle's computer that a new battery has been installed, allowing it to optimize charging and prolong battery life. Failing to do this can lead to premature battery failure or issues with electrical accessories.

Here's a common procedure for a BMS reset (always refer to your owner's manual for specific instructions):

1. With the ignition off, connect the new battery.
2. Close the hood and all doors.
3. Start the engine and let it idle for at least 30 seconds.
4. Turn off all accessories (radio, lights, A/C, etc.).
5. Turn the ignition to the "ON" position (do not start the engine) for at least 10 seconds. Then turn the ignition OFF.
6. Repeat step 5 two more times.

Some vehicles may require a more advanced reset procedure using a diagnostic scan tool. If you experience persistent electrical issues after battery replacement, consult a professional technician.

Signs of a Failing Battery

Don't wait for your battery to die completely before replacing it. Here are some common signs that your 2017 Ford Explorer's battery is on its way out:

• Slow Engine Crank: The engine turns over sluggishly when you try to start it.
• Dim Headlights: Headlights appear dimmer than usual, especially when the engine is off.
• Warning Lights: A battery or check engine light illuminates on your dash.
• Corrosion on Terminals: White or bluish powder around the battery posts can indicate a leak or poor connection.
• Swelling Battery Case: A bulging or cracked battery case is a clear sign of internal damage and a dangerous condition.
• Electrical Gremlins: Intermittent issues with power windows, radio, or other electronic accessories.
• Frequent Jumps: If you find yourself needing jump starts more often.

Common Battery Issues for This Generation

The 2017 Ford Explorer isn't known for any unique or widespread battery issues beyond what's common for vehicles of this era. However, a few factors can contribute to premature battery failure:

• Parasitic Draws: Even when off, some electrical components can slowly drain the battery. Aftermarket accessories are common culprits.
• Short Trips: Frequent short drives don't allow the alternator enough time to fully recharge the battery.
• Extreme Temperatures: Both very hot and very cold weather can stress batteries, shortening their lifespan.
• Start-Stop System: While designed for it, the start-stop system does put more demand on the battery, making an AGM battery virtually a requirement for optimal life and performance.

Regular testing of your battery, especially as it approaches 3-5 years old, can help you avoid unexpected breakdowns.
