• Do not let a wrench touch both battery terminals or metal body parts at the same time.
• If your Golf has an alarm or radio memory concern, be aware power will be lost during the swap.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and secure it.
• Remove any plastic engine cover or intake ducting blocking access if equipped.
• Use your hands first, then the appropriate tool only if fasteners are present.

Step 2: Disconnect the negative terminal

• Use a 10mm wrench to loosen the negative terminal clamp.
• Lift the negative cable off the battery post and move it aside so it cannot spring back.
• Always remove negative first.

Step 3: Disconnect the positive terminal

• Use the 10mm wrench to loosen the positive terminal clamp.
• Remove the positive cable from the battery post and keep it clear of metal.

Step 4: Remove the battery hold-down

• Use a 13mm socket, ratchet, and short extension to remove the battery hold-down bolt.
• Remove the hold-down clamp and set the hardware aside.
• Lift carefully; batteries are heavy.

Step 5: Remove the old battery

• Use a battery carrying strap if needed and lift the battery straight up and out.
• Keep it level to avoid acid spill if the battery case is damaged.

Step 6: Clean the battery tray and terminals

• Use a battery terminal brush to clean corrosion from the cable ends if present.
• Wipe the battery tray clean before installing the new battery.
• Clean metal makes a better connection.

Step 7: Install the new battery

• Place the new battery in the tray in the same direction as the old one.
• Install the hold-down clamp and use the 13mm socket to tighten it.
• Torque to 20 Nm (15 ft-lbs).

Step 8: Reconnect the terminals

• Install the positive cable first and tighten it with the 10mm wrench.
• Install the negative cable last and tighten it with the 10mm wrench.
• Torque to 6-8 Nm (53-71 in-lbs) for the terminal clamps.

Step 9: Finish up
