This guidance is for choosing batteries for general practical circuit work, where pupils experiment with low-voltage circuits by connecting batteries , torch bulbs, buzzers, small motors and other low-power components to investigate electrical characteristics, parallel and series circuits, etc. 

The production of a one-piece component from molten metal poured into the cavity of a mould which may be of sand, steel, plaster or cuttlefish ‘bone’ and the use of low-melting point metals.
