A primary cell is a battery that is made to be used one time only. It cannot be recharged. Once all the power is used up, the battery must be thrown away. It no longer makes electricity. Primary cells are often used to give power to small appliances that are used in the home.

The good things about this kind of disposable battery are:

  • it costs less money
  • it is easier to make
  • it can last longer before being used (shelf life)
  • it is easily available to buy

The bad things are:

  • it is making waste when thrown away
  • it can be made with toxic materials
