††††There are two main types of battery: primary and secondary cells. Primary cells continue to produce electricity until they are exhausted, whereas secondary cells (such as car batteries) may be recharged with electricity.
Most small everyday batteries are 'dry' batteries, which were first devised in 1868 by Frenchman Georges Leclanche. Although the principle he devised can also be used to make a wet battery, this has fewer uses. Single cell batteries can be laid end to end to provide extra power for larger devices such as tape recorders.
