Many electronic devices run off batteries as their energy source.  The ideal battery is a source of voltage, when connections are made to it current will flow, the amount depending on the connections.  For the ideal battery the voltage will not fall when current is drawn, or time goes by.  For real batteries none of this is true, but may be useful approximations.  An improved model of a battery is that it is an ideal voltage source in series with an ideal resistor ( known as the internal resistance of the battery ).  A battery is a collection of cells so a single cell battery is really just a cell, not a battery.
