A connection mechanism includes a metal segment in mechanical and electrical communication with the remainder of the connection mechanism on at least one side. The segment includes at least one tab protruding from the segment on a first side and a central area of the segment with a plurality of metal deformations. When the metal deformations are pressed into aluminum, they are capable of piercing through corrosion on the surface of the aluminum in order to make electrical contact with the aluminum.
