Step 1: Gather the Necessary Tools

Before starting the battery replacement process, it’s important to gather all the necessary tools. You will need a socket wrench, a set of sockets, a battery terminal cleaner, a wire brush, and a new battery that is compatible with your 2018 Ram 3500.

Step 2: Ensure Safety

Prior to replacing the battery, it’s crucial to ensure your safety. Park your Ram 3500 in a well-ventilated area, away from any open flames or sparks. Additionally, remember to wear safety glasses and gloves to protect yourself from any potential hazards.

Step 3: Disconnect the Negative Terminal

The first step in replacing the battery is to disconnect the negative terminal. Locate the negative terminal, which is usually marked with a minus (-) sign. Loosen the nut on the negative terminal using a socket wrench and then disconnect the terminal from the battery.

Step 4: Disconnect the Positive Terminal

After disconnecting the negative terminal, proceed to disconnect the positive terminal. The positive terminal is usually marked with a plus (+) sign. Again, use a socket wrench to loosen the nut and disconnect the terminal from the battery.

Step 5: Remove the Old Battery

Once both terminals are disconnected, carefully remove the old battery from your Ram 3500. Be cautious not to spill any battery acid or damage the battery in the process. Use a battery carrier or a pair of gloves to ensure a secure grip while removing the battery.

Step 6: Clean the Battery Terminals

With the old battery removed, it’s crucial to clean the battery terminals before installing the new battery. Use a battery terminal cleaner or a wire brush to remove any corrosion or build-up from the terminals. Clean both the positive and negative terminals thoroughly.

Step 7: Install the New Battery

Now it’s time to install the new battery. Carefully place the new battery in the battery tray, ensuring that it is securely seated. Connect the positive terminal first, tightening the nut with a socket wrench. Repeat the process for the negative terminal, ensuring a tight connection.

Step 8: Double-Check Connections

After installing the new battery, it’s essential to double-check all the connections. Ensure that both the positive and negative terminals are securely attached to the battery. Tighten any loose connections with a socket wrench if necessary.

Step 9: Test the New Battery

With the new battery installed and all connections secure, it’s time to test the battery. Start your Ram 3500 and check if it starts without any issues. If everything is functioning correctly, you have successfully replaced the battery in your 2018 Ram 3500.
