⚠️ Safety & Precautions

• ⚠️ Always work with the engine off, ignition off, key removed, and doors closed to avoid electrical issues.
• ⚠️ Never touch the positive and negative battery terminals at the same time with tools or jewelry.
• ⚠️ Remove the negative (–) cable first and reconnect it last to reduce the risk of short circuits.
• ⚠️ Wear safety glasses and gloves; battery acid can irritate skin and eyes.
• ⚠️ Do not smoke or create sparks near the battery; explosive gas may be present.
• ⚠️ Your Escape has a battery monitoring sensor on the negative cable; handle the sensor gently and do not pry on it.
• ⚠️ Battery disconnect will reset clock/radio presets and may reset window auto-up/down; this is normal.

📋 Before You Begin

• Park your Escape on level ground, shift to P, and set the parking brake.
• Turn off all electrical loads: lights, radio, blower fan, and unplug chargers.
• Open the hood and secure it with the prop rod.
• If you have a memory saver tool (keeps power to the car while battery is out), connect it per its instructions now. Optional but helpful for keeping presets.
• Wait at least 5 minutes after shutting the engine off so control modules go to “sleep.”

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and uncover the battery

• Open the hood and look at the left side (driver side) near the firewall; that’s where the battery sits.
• The battery has a plastic cover on top. Use the flathead screwdriver to gently release any plastic tabs or clips on the cover, then lift the cover off.
• Set the cover aside in a clean place. Keep small clips where you can see them.

Step 2: Identify positive and negative connections

• The positive (+) terminal usually has a red cover or red cable.
• The negative (–) terminal usually has a black cable and includes a small plastic sensor module on this Escape.
• Note how the cables are routed and where the battery hold-down bracket is at the base.

Step 3: Disconnect the negative (–) battery cable first

• Use the 10mm socket and ratchet to loosen the nut on the negative (–) terminal clamp. You only need to loosen, not remove the nut.
• Gently twist the clamp side-to-side and lift it off the battery post. Do not pry on the sensor.
• Move the cable away from the battery and wrap the clamp in a shop towel or rag so it cannot spring back onto the terminal.
• Negative first reduces sparks and protects electronics.

Step 4: Disconnect the positive (+) battery cable

• Flip open any red plastic cover on the positive (+) terminal.
• Use the 10mm socket and ratchet to loosen the nut on the positive clamp.
• Carefully lift the positive clamp off the battery post and move it aside so it cannot touch metal or the negative terminal.
• Reposition the cable so it rests safely; if needed, wrap it in a shop towel.

Step 5: Remove the battery hold-down bracket

• At the base of the battery there is a metal or plastic clamp that holds it in place.
• Use the 13mm socket, extension, and ratchet to remove the hold-down bolt.
• Lift out the hold-down bracket and set it aside.
• Torque spec on reinstall: 8–10 Nm (6–7 ft-lbs)

Step 6: Lift out the old battery

• Batteries are heavy; use both hands and lift straight up. If your battery has a built-in handle, use it.
• Keep the battery upright to avoid any acid leaks.
• Place the battery on the ground, away from your feet and the car. Use your legs, not your back.

Step 7: Clean the battery tray and terminals

• Check the battery tray for dirt or corrosion. Wipe it out with a shop towel.
• Inspect the cable clamps for white/green corrosion.
• If needed, use the battery terminal brush to gently clean the inside of the clamps until shiny metal is visible.
• Do not scrub the plastic sensor on the negative cable; only clean the metal clamp surface.

Step 8: Place the new battery in the tray

• Make sure the new battery has the same terminal layout (positive and negative in the same positions as the old one).
• Set any battery anti-corrosion pads on the tray where the posts will sit if you are using them.
• Lower the new battery into the tray carefully, keeping it upright. Positive and negative terminals must line up with the correct cables.

Step 9: Reinstall the battery hold-down

• Reposition the hold-down bracket at the base of the battery.
• Install the bolt using the 13mm socket, extension, and ratchet.
• Tighten until snug, but do not overtighten: Torque to 8–10 Nm (6–7 ft-lbs).
• Battery should not move if you push it.

Step 10: Connect the positive (+) cable

• Place the positive (+) clamp fully down on the positive battery post.
• Use the 10mm socket and ratchet to tighten the clamp nut until the clamp does not move when you twist it by hand.
• Torque to 7–9 Nm (5–7 ft-lbs).
• Close the red plastic cover over the terminal if equipped.

Step 11: Connect the negative (–) cable

• Place the negative (–) clamp fully down on the negative battery post, making sure the sensor is not twisted or stressed.
• Use the 10mm socket and ratchet to tighten the clamp nut until the clamp does not move when you twist it by hand.
• Torque to 7–9 Nm (5–7 ft-lbs).
• Negative is always connected last for safety.

Step 12: Apply terminal protection and reinstall cover

• Lightly spray the terminals and clamps with battery terminal protector spray if you have it. Avoid overspray on paint.
• Reinstall the plastic battery cover by lining it up and pressing any tabs or clips back into place. Use the flathead screwdriver if needed to help seat clips.

Step 13: Perform battery monitoring reset (recommended)

• Your Escape has a Battery Monitoring System (BMS) that should be told a new battery is installed so charging is correct.
• Connect your OBD2 scan tool with Ford battery reset function to the OBD2 port under the dash.
• Follow the tool menu to perform a battery replacement or BMS reset for Ford vehicles. Menu path example (varies by tool): Ford > Escape > Body > BCM > Special Functions > Battery Monitoring Reset.
• If you do not have such a tool, the car will relearn over time, but charging behavior may not be perfect at first.

Step 14: Basic system resets in the cabin

• Start the engine and let it idle for a few minutes.
• Set the clock and radio presets again if they were lost.
• If any window auto-up/down does not work, re-learn it: with ignition on, hold the window switch all the way down until the window fully opens, hold for 2 seconds, then hold all the way up until fully closed and hold for 2 seconds.

✅ After Repair

• Start the engine and make sure it cranks quickly and runs smoothly.
• Check that all lights, wipers, horn, and infotainment work normally.
• Confirm that no new warning lights stay on in the instrument cluster.
• Take a short drive (10–15 minutes) so the charging system can adjust.
• Over the next few days, glance at the battery area to ensure the hold-down is secure and there are no signs of corrosion or leaks.
