Right Angle Battery Terminals are manufactured from pure copper to provide the highest electrical conductivity in a battery connection. The terminals are tin plated making them easy to solder and to protect against corrosion. Right angle copper battery terminals come in two sizes - 1/0 AWG and 2/0 AWG, and are available in both positive and negative polarity. The polarity and gauge size is marked on the terminal for easy identification. The ends of the battery terminals are flared to make it easier to insert your battery cables. Comes with a mounting bolt and nut to attach to the top posts of your automotive or marine battery.
