The energy of this electron flow, or electricity, can be tapped by connecting a load, be it a light bulb or a motor, to the path of flowing electrons. The supply of electrons in the battery comes from the chemical process of ionization described in basic chemistry texts. Once this process is set in motion and if a wire connects the two terminals the flow of electrons starts. Without a connection, no flow occurs because no chemical reaction has been set off. This helps explain why batteries have a surprisingly long shelf life. On the other hand, very concentrated or rapid flow of electrons between terminals (measured in terms of internal resistance) can have the effect of wearing out the battery. Inventors of the earliest batteries devised the voltaic pile as a means of controlling internal resistance.
