A battery terminal is a conductive point on a battery where electrical connections are made. It typically consists of a positive terminal, marked with a "+" sign, and a negative terminal, marked with a "-" sign. These terminals allow for the transfer of electrical energy to and from the battery, enabling devices like cars and electronic gadgets to function. Battery terminals are usually made of metal, such as lead or copper, to ensure good conductivity. Proper maintenance of battery terminals is essential, as corrosion or loose connections can lead to poor performance or failure of the battery. Regular cleaning and secure connections help maintain optimal functionality.
