🔧 1500 - 12V Battery Replacement

This procedure replaces the under-hood 12-volt battery in your 1500. The 12V battery powers the starter controls, computers, lights, and accessories, even though your 1500 also has the mild-hybrid eTorque system.

Difficulty Level: Beginner | Estimated Time: 30-60 minutes

⚠️ Safety & Precautions

• ⚠️ Your 1500 has a 48V mild-hybrid eTorque system. Do not touch orange high-voltage cables or hybrid components.
• ⚠️ This repair is for the regular 12V battery only, located under the hood.
• ⚠️ Always remove the negative battery cable first and install it last to reduce spark risk.
• ⚠️ Wear safety glasses and gloves. Batteries contain acid and can vent explosive gas.
• ⚠️ Keep metal tools away from both battery terminals at the same time.
• ⚠️ Battery disconnect is required for this repair.

📋 Before You Begin

• Park your 1500 on level ground, shift to Park, and set the parking brake.
• Turn off all lights, HVAC, radio, and accessories.
• Remove the key fob from the truck and keep it at least 15 feet away.
• Open the hood and wait at least 5 minutes so the modules can go to sleep.
• If using a memory saver 12V OBD-II, plug it into the diagnostic port before disconnecting the battery. A memory saver is a small backup power device that helps retain clock, radio, and module memory.
• Do not open doors or press the brake pedal while the battery is disconnected.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the 12V Battery

• Open the hood and locate the 12V battery on the passenger side of the engine bay.
• Use safety glasses and nitrile gloves before touching the battery.
• Identify the negative terminal marked - and the positive terminal marked +.
• Take a photo before removal.

Step 2: Disconnect the Negative Cable

• Use a 10mm wrench or 10mm socket to loosen the negative battery terminal clamp nut.
• Twist the negative cable gently and lift it off the battery post.
• If the terminal is stuck, use a battery terminal puller. A battery terminal puller safely lifts a tight cable clamp without damaging the battery post.
• Move the negative cable aside so it cannot touch the battery post.

Step 3: Disconnect the Positive Cable

• Lift the red protective cover from the positive terminal.
• Use a 10mm wrench or 10mm socket to loosen the positive battery terminal clamp nut.
• Lift the positive cable off the battery post and move it aside.
• Do not let the positive cable touch metal body parts.

Step 4: Remove the Battery Hold-Down

• Locate the battery hold-down bracket at the base of the battery.
• Use a 10mm socket, ratchet handle, and 6-inch socket extension to remove the hold-down bolt.
• Remove the hold-down bracket and set it aside.
• Do not drop the bolt.

Step 5: Remove the Old Battery

• Attach a battery carrying strap to the battery if the battery does not have a handle.
• Lift the battery straight up and out of the tray. Batteries are heavy, so keep your back straight and use both hands.
• Place the old battery upright on the ground.
• Check the battery tray for acid residue, dirt, or loose hardware.

Step 6: Clean the Battery Cable Ends

• Use a battery terminal cleaning brush to clean the inside of both cable clamps.
• Also clean the battery tray area if dirt or corrosion is present.
• Do not use water near open electrical connectors.
• Clean metal makes better contact.

Step 7: Install the New Battery

• Use a battery carrying strap to lower the new 12V AGM battery into the tray.
• Make sure the positive post is on the same side as the positive cable.
• Reinstall the hold-down bracket using the 10mm socket, ratchet handle, and 6-inch socket extension.
• Tighten the hold-down securely. Do not over-tighten and crack the battery case.

Step 8: Connect the Positive Cable First

• Install one battery terminal anti-corrosion washer on the positive post.
• Push the positive cable fully down onto the positive battery post.
• Use a 10mm socket and torque wrench inch-pound to tighten the terminal clamp nut.
• Torque to 7 Nm (62 in-lbs).
• Close the red protective cover over the positive terminal.

Step 9: Connect the Negative Cable Last

• Install one battery terminal anti-corrosion washer on the negative post.
• Push the negative cable fully down onto the negative battery post.
• Use a 10mm socket and torque wrench inch-pound to tighten the terminal clamp nut.
• Torque to 7 Nm (62 in-lbs).
• Apply battery terminal protector spray lightly to both terminals after tightening.

Step 10: Wake Up the Truck

• If you used a memory saver 12V OBD-II, unplug it now.
• Close the hood enough to latch it, then enter the truck.
• Start your 1500 and let it idle for 2-3 minutes.
• Use the touchscreen to reset the clock if needed through Apps > Settings > Clock.
