The examples below show how the method of connecting cells to form a battery will determine
the terminal voltage.
Figure 1-5 shows two 1.5 volt cells connected in series. The terminal voltage of the battery is
Figure 1-6 shows two 1.5 volts cells connected in parallel. The terminal voltage of the battery
is 1.5 volts.
The method of connecting cells to form a battery will determine the terminal voltage and
current capacity of the battery.
Series connection of cells means that the negative (-) electrode of one cell is connected to
the positive (+) electrode of the next cell. When cells are connected using this method, you
can determine the terminal voltage of the battery by adding the cell voltages together. The
current capacity of a battery of series-connected cells is the same as the current capacity of
The symbol for cell is
The short line is the negative side of the cell and
the long line is the positive side.
