📋 Before You Begin

• Park on level ground, shift to Park, and shut the engine off.
• Open the hood and keep the key fob at least 10 feet away from the vehicle so modules can go to sleep.
• Wait about 5 minutes before disconnecting the battery.
• If you want to keep radio presets, use a memory saver through the OBD port (optional). A memory saver is a small device that maintains power while the battery is disconnected.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery in the engine bay.
• Remove the battery cover (if equipped) using a trim clip tool for any push clips, then lift the cover off by hand.

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket with a 1/4" ratchet to loosen the negative terminal clamp nut.
• Twist the clamp gently and lift it off the battery post.
• Tuck the cable end to the side so it cannot spring back onto the terminal.

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket with a 1/4" ratchet to loosen the positive terminal clamp nut.
• Lift the clamp off the battery post and move it safely aside.
• Tip: Cover the + clamp with a rag.

Step 4: Remove any battery vent tube (if equipped)

• If your battery has a small vent hose attached to the side, pull it off gently by hand.

Step 5: Remove the battery hold-down

• At the base of the battery, remove the hold-down bolt using a 13mm socket, 3/8" ratchet, and 6" socket extension.
• Remove the hold-down bracket and set it aside.

Step 6: Remove the old battery

• Lift the battery straight up and out using the built-in handle (it’s heavy).
• Set it on the ground upright.

Step 7: Clean and prep the terminals

• Use a battery terminal brush to clean the inside of both cable clamps until the metal looks bright.
• Wipe with shop rags.
• Install battery terminal anti-corrosion pads on the battery posts (one per post).

Step 8: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket and bolt using a 13mm socket and 3/8" ratchet.
• Tighten securely with a torque wrench: Torque to 10 Nm (89 in-lbs).
• Reconnect the vent tube by pushing it on by hand (if equipped).

Step 9: Reconnect the cables (positive first)

• Install the positive (+) cable clamp onto the battery post.
• Tighten the clamp using a 10mm socket and 1/4" ratchet: Torque to 6 Nm (53 in-lbs).
• Install the negative (-) cable clamp last.
• Tighten using a 10mm socket and 1/4" ratchet: Torque to 6 Nm (53 in-lbs).
• Spray a light coat of battery terminal protectant spray on both connections.

Step 10: Reset the Battery Monitoring System (BMS)

• The BMS reset tells the Escape it has a new battery so charging works correctly.
• Manual reset (no scan tool):
  • Turn ignition to ON (engine OFF).
  • Within 10 seconds: flash the high beams 5 times.
  • Then press and release the brake pedal 3 times.
  • Watch the battery warning light; it should flash to confirm the reset.
• Scan tool method (if available): Use a capable scan tool and run the BMS/battery replacement reset function.

Step 11: Reinstall the battery cover

• Reinstall the battery cover and any clips using your hands and the trim clip tool.
