THE DRY CELL BATTERY
CHEMISTRY:
A current is produced basically by the flow of electrons. The dry cell, or Leclanche battery works by creating two electrochemically different ends (an anode and a cathode) so current passes through when a complete circuit is connected. This involves non-renewable compounds which initiate reactions at both ends of the cell. These reactions allow the flow of ions which ultimately produce the current.

…as ¡§The Green Battery¡¨ due to the materials used in it¡¦s construction and for it¡¦s ability to integrate with natural power sources such as wind and solar. Alternative battery systems contain heavy metals such as lead, nickel, zinc and cadmium all of which have potentially adverse environmental impacts during production, use and disposal. The electrolytes used in VRB have an indefinite life, there are no disposal issues as the electrolytes are completely reusable.
