Battery Terminal

An automotive battery terminal is a metal component that connects the battery cables to the battery. The terminal is typically made of lead, brass, or aluminum, and it serves as a point of contact between the battery and the electrical system of the vehicle. The battery terminal usually has two connections, one for the positive (+) battery cable and the other for the negative (-) cable. The positive terminal is typically larger than the negative terminal, and it is marked with a plus sign (+) or the letters "POS." The negative terminal is marked with a minus sign (-) or the letters "NEG." When the battery is installed in the vehicle, the positive terminal is connected to the starter, alternator, and other electrical components that require power, while the negative terminal is connected to the vehicle's chassis, providing a ground. The battery terminal serves as a critical point of connection, ensuring that the electrical system of the vehicle has the power it needs to function properly. Over time, corrosion can build up on the battery terminals, leading to poor connections and electrical issues. It is essential to keep the battery terminals clean and free of corrosion to maintain proper electrical function in the vehicle.
