How the batteries work
Basic
batteries have two terminals, positif (+) and negatif (-), but
in a AA, C or D battery, the terminals are the sides. Batteries
work by the electrons which are formed on the negative side of
the battery; it works by a chemical reaction in the battery, which
produces the electrons. The electrons go to a cord which goes
from the negative terminals to the positive terminals. So if the
chemical reaction is not active, the battery does not lose its
energy. That's why batteries can work for a very long time.
