All batteries have two places where they join, or connect to an electric circuit.  These places are called terminals.  One is labelled with a + and the other one is labelled with a -.  These labels mean plus and minus.  All devices such as remote controls, clocks, and smoke detectors clearly show the plus and minus labels.

Mobile phones, music players and laptop computers or get their electricity from batteries.  This means we can take them where we like.  Many electric power tools such as drills saws and screwdrivers get their electricity from batteries.  These tools are known as cordless tools because they have no power cord.
