Batteries

Batteries come in all different sizes, voltages and chemical composition. From button batteries to AA and 9V batteries. When swallowed, the left-over electrical current in a button battery reacts with moisture to produce a strong alkali chemical. The chemical can cause serious internal burns and bleeding. The batteries can also leak chemicals which can cause serious burns. Button batteries are easily caught in the oesophagus, and when stuck can start to cause damage very quickly.
