King Louie is a supporting character from the 1967 Disney animated feature, The Jungle Book. Louie is an orangutan, inspired by Rudyard Kipling's classic novel. Louie did not appear in the book, however, because orangutans are not native to India.
Quick Answer. Overfilling the battery, poor design of the vent cap, age and distortion of the gaskets can all cause battery terminal corrosion. Nitrogen gas is emitted by the electrolyte in the battery. Material in the battery terminals and cable ends reacts with the nitrogen gas, and corrosion begins to form. Keep Learning.
Galvanic corrosion can only occur when two electrochemically different metals are close to one another and also submerged in an electrolytic liquid (such as salt water). When this occurs, the metals and the electrolyte create a galvanic cell. The cell has the effect of corroding one metal at the expense of the other. In the case of the Alarm, the iron was corroded at the expense of the copper.
