📋 Before You Begin

• 🅿️ Park your 1500 on level ground, shift to Park, and set the parking brake.
• 🔑 Turn the ignition OFF and remove the key fob from the cab area.
• ⏱️ Wait at least 2 minutes before disconnecting the battery so modules can go to sleep.
• 📸 Take a quick photo of the battery cable routing before removal.
• 🧠 A battery terminal puller is a small tool that lifts a stuck battery cable end without prying on the battery post.
• 🧠 A torque wrench tightens fasteners to a measured amount so they are not too loose or too tight.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood and Locate the Battery

• Use your hands to release the hood latch and raise the hood fully.
• The battery is on the passenger-side front area of the engine compartment.
• Use safety glasses and nitrile gloves before touching the battery.

Step 2: Remove the Negative Battery Cable

• Find the negative terminal marked with a minus sign (-).
• Use a 10mm socket, 3/8-inch drive ratchet, and 6-inch extension to loosen the negative terminal clamp nut.
• Lift the negative cable off the battery post by hand.
• If it is stuck, use the battery terminal puller (specialty).
• Move the cable aside so it cannot spring back and touch the battery post.
• Never pry on the battery case.

Step 3: Remove the Positive Battery Cable

• Find the positive terminal marked with a plus sign (+).
• Open the red protective cover by hand if equipped.
• Use a 10mm socket, 3/8-inch drive ratchet, and 6-inch extension to loosen the positive terminal clamp nut.
• Lift the positive cable off the battery post by hand.
• If it is stuck, use the battery terminal puller (specialty).
• Move the positive cable away from the battery.

Step 4: Remove the Battery Hold-Down

• The hold-down is the bracket that keeps the battery from sliding around.
• Use a 13mm socket, 3/8-inch drive ratchet, and 6-inch extension to remove the battery hold-down bolt.
• Lift the hold-down bracket out by hand and set it aside.

Step 5: Remove the Old Battery

• Attach the battery carrier strap (specialty) to the old battery if needed.
• Lift the battery straight up and out of the tray.
• Keep the battery level while carrying it.
• Set it on the ground carefully.
• Batteries are heavier than they look.

Step 6: Clean the Battery Tray and Cable Ends

• Use the battery terminal cleaning brush to clean the inside of both cable clamps.
• Use the battery terminal cleaning brush to clean light corrosion from the battery tray area.
• If you see heavy white or blue-green corrosion, avoid breathing dust and clean gently while wearing safety glasses and nitrile gloves.

Step 7: Install the New Battery

• Use the battery carrier strap (specialty) to lower the new 12-volt AGM starting battery into the tray.
• Make sure the positive and negative posts are in the same positions as the old battery.
• Install the battery anti-corrosion washers over the battery posts by hand.
• Make sure the battery sits flat in the tray.

Step 8: Reinstall the Battery Hold-Down

• Install the hold-down bracket by hand.
• Use a 13mm socket, 3/8-inch drive ratchet, and torque wrench inch-pound to tighten the hold-down bolt.
• Torque to 5 Nm (44 in-lbs).
• Do not overtighten. The battery case can crack.

Step 9: Connect the Positive Battery Cable

• Push the positive cable clamp fully onto the positive battery post by hand.
• Use a 10mm socket, 3/8-inch drive ratchet, and torque wrench inch-pound to tighten the positive terminal clamp nut.
• Torque to 6 Nm (53 in-lbs).
• Close the red protective cover by hand if equipped.

Step 10: Connect the Negative Battery Cable

• Push the negative cable clamp fully onto the negative battery post by hand.
• Use a 10mm socket, 3/8-inch drive ratchet, and torque wrench inch-pound to tighten the negative terminal clamp nut.
• Torque to 6 Nm (53 in-lbs).
• A small spark can happen when connecting the final cable. That is normal.

Step 11: Protect the Terminals

• Use battery terminal protectant spray lightly on both connected battery terminals.
• Do not soak the terminals. A light coating is enough.

Step 12: Verify Startup

• Use your key fob to unlock the truck if needed.
• Start the engine and make sure it cranks strongly.
• Use your eyes to confirm the battery does not move and both cable clamps stay tight.
