Battery Terminals

The battery terminals are the points on the battery to which you connect your wires. Some cars have the "post" type that use clamps. This type is slowly being phased out by the "side-mount" type of terminals which use a bolt to screw into the side of the battery and clamp on the battery wire. Battery terminals are a problem in many cars, because vapors from battery acid causes corrosion to form on the lead surfaces and copper wiring associated with the battery wires. It is a good idea to clean these periodically, but wash your hands thoroughly after cleaning the terminals because the corrosion on the terminals is also acidic.
