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.
What causes corrosive build-up on the battery terminals, as seen in the picture, is a combination of hydrogen gas produced by the chemical reactions in the battery, and the dirt and sediment on the terminals. For this reason keeping a clean battery before corrosion occurs will help prevent the problem from starting. keeping grease or petroleum jelly on the terminals will prevent battery acid build up as well. Other car battery maintenance may include putting water in the cells when needed.
