The Batteries and Cells Electricity wall chart is a clear and engaging educational poster that explains the fundamental difference between a cell and a battery. It introduces learners to basic electrical concepts using familiar examples such as AA and car batteries, making abstract ideas easier to understand.

The chart begins by defining a cell as a source of DC electricity and visually demonstrates how multiple cells connected together form a battery. A large, detailed illustration shows how cells are connected in series, helping learners understand voltage buildup in a simple and practical way. The section on how a battery works explains positive and negative terminals, electron flow, and why a load such as a globe is required in a circuit.

A key educational feature of this poster is the internal structure diagram of a dry cell. Components such as the zinc case, carbon rod, manganese dioxide, ammonium chloride, and positive and negative poles are clearly labelled. This helps learners understand how chemical reactions inside a cell produce electrical energy.

The wall chart is ideal for science and technology classrooms, supporting lessons on electricity, energy transfer, and circuits. This poster works well as a visual aid, revision tool, and discussion starter for practical investigations involving batteries and cells.
