When removing a car battery, should the positive or negative terminal be disconnected first?

[VanAriana]

Disconnect the negative terminal first when removing the battery. Here are the relevant steps for battery removal: 1. Before replacing the battery, check if it is completely depleted. If the battery is cracked, replace it immediately. If not, first inspect both terminals of the battery. Sometimes, sulfate formation can corrode the battery terminals. Try scrubbing them with a brush dipped in a mixture of baking soda and water. The battery might still be usable. 2. Turn off the engine before replacement. Carefully loosen the battery screw connected to the negative terminal with a wrench and remove the cable clamp from the terminal. Then, remove the positive terminal in the same manner. Firmly grasp the battery and remove it from the car. After removal, take a moment to clean the clamps and battery tray with soda water. 3. Installation: Carefully place the new battery in the battery tray. Ensure the positive and negative terminals are correctly positioned, then secure the battery by tightening the bracket. Connect the positive terminal first, followed by the negative terminal. Finally, close the hood.
