Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Power generated by reaction of the metals is used to power a small device such as a light emitting diode (LED). The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta, who used brine (salt water) instead of lemon juice.

Electric motorcycles and scooters fuel rationing in the United States, Merle Williams of Long Beach, California invented a two-wheeled electric motorcycle that towed a single wheeled trailer. Due to the popularity of the vehicle, Williams started making more such vehicles in his garage. In 1946, it led to the formation of the Marketeer Company (current-day ParCar Corp.). In 1967, Karl Kordesch, working for Union Carbide, made a fuel cell/Nickel–cadmium battery hybrid electric motorcycle. It was later replaced with a hydrazine fuel cell, giving it a range of per gallon and a top speed of . In the same year, a prototype electric motorcycle called
