When attaching a wire to anything such as a crimp connector or a ring terminal to a battery terminal there is a term called "gas tight connection". This means the connection between the wire and what it is connected to is compressed enough that oxygen molecules can't penetrate the connection. If oxygen can penetrate the connection you will get oxidation. Most people don't understand how to or have the tools to properly crimp a terminal onto a wire. Battery terminals that are not clean and gas tight can get oxidation, a bad connection and that causes heat that can melt the terminal.
