What is a battery?

• A battery is an electrical device that converts
  chemical energy to electricity. At this point,, I
  would like to state that batteries can be grouped
  into two many groups. These are
• Primary
• Secondary.
• Primary cell batteries
• These are batteries that are made in such a way
  that once you use them, they can't be recharged.
  In short primary batteries are disposable

4
Application of primary cell batteries.

• As said earlier, this type of cell can not be
  recharged. This is because the chemical
  conversion of the batteries to electricity can
  not be reversed. Examples of primary cells are
• Leclanche cell-These cells are used in Torches,
  transistor radio, and bells.
• Mercury cell-These cell is being used in Hearing
  aids, medical electronics, cameras, and guided
  missiles.

5
Secondary cell batteries

• As you can guess, these batteries are made in
  such a way that once they lose the charge, they
  can be recharged.
• These battery cells are rechargeable. This is
  possible because the conversion of chemical
  energy to electric energy is reversible and the
  cell can be used many times. Examples of
  secondary cells are
• Lead-acid cell
• Nickel-cadmium cell and Nickel-metal cell.

6
Application of secondary cell batteries.

• Car batteries
• Telephone circuits
• Forklift
• Delivery van.

ALTERNATIVE AND RENEWABLE SOURCES OF ENERGY

• Alternative energy.
• An alternative source of energy is any source of
  energy that can replace the traditional sources
  of energy. Like gas, coal and oil that can harm
  and pollute the ozone. traditional sources of
  energy tend to increase the atmospheric carbon
  when banned as fuel.
• Renewable energy.
• A renewable source of energy is a source that is
  automatically replenished or one that doesn't get
  depleted as it is being used. Renewable sources
  of energy can be said to be infinity.
