Summary: Description of a electric battery for use by signal troops.
Description: The battery is shown in close-up. Diagrams show how it is prepared for use by filling with water and connecting to the circuit, and how the resulting chemical reaction causes the electrodes to corrode. This is illustrated by film of an exhausted battery being sawn open. Finally the film shows how the voltage produced gives an indication of the state of the battery; this is shown being tested.
