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.
Overcharging by the alternator and bad contact between the terminals can cause battery corrosion. Keeping the terminals clean and tight will prevent the corrosion from bad contacts. An old battery that is in bad shape or a faulty alternator can cause the overcharging. Below is a link for cleaning battery corrosion.
