Disconnect the negative terminal first when changing a car battery. Then, remove the positive terminal. When connecting a new battery, attach the positive terminal first, followed by the negative. This disconnect order ensures safety and prevents electrical shorts during battery replacement. Remember these safety tips for a smooth process.
When you begin the process, the order of disconnecting the battery terminals is vital for safety. Always remove the negative terminal first. The negative terminal is usually marked with a minus sign (-) and is connected to the car’s frame. Removing it first helps prevent accidental short-circuits. Once the negative terminal is disconnected, proceed to the positive terminal. The positive terminal is marked with a plus sign (+) and connects to the battery.
After removing both terminals, lift the old battery out with caution. Place the new battery in position and connect the positive terminal first, followed by the negative terminal. This method ensures that you reduce the risk of sparks.
Now that you know how to safely change a car battery and the proper terminal order, let’s explore the signs indicating that it’s time for a battery replacement. Recognizing these signs early can prevent unexpected breakdowns and maintain your vehicle’s performance.
