context_page_description: A battery converts chemical energy into electrical energy by a chemical reaction. Usually the chemicals are kept inside the battery. It is used in a circuit to power other components. A battery produces direct current electricity.
  Using the electricity from an outlet in a building is cheaper and more efficient, but a battery can provide electricity in areas that do not have electric power distribution. It is also useful for things that move, such as electric vehicles and mobile phones.
  Batteries may be primary or secondary. The primary is thrown away when it can no longer provide electricity. The secondary can be recharged and reused.
