When you get the lug replaced, be sure to clean the terminals thoroughly with a small brass or stainless steel wire brush. Use Marine grade terminals made of tinned copper, and use adhesive-lined heat shrink on the cable and lug to seal out moisture.
When you put it all back together (ending with the negative lead), spray the connections with the red battery terminal sealant to keep moisture and acid vapor away from the terminals.
