Lemon battery Lemon battery A lemon battery is a simple battery often made for the purpose of education. 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. The lemon battery illustrates the type of chemical reaction
Battery electric multiple unit Merseyrail Wirral Line and extend into the underground section of Liverpool's city centre. The line is diesel train operated unable to progress into the electric 3rd rail underground Birkenhead and Liverpool Merseyrail tunnels. The diesel operated line terminates at Bidston railway station in Birkenhead, with passengers having to change trains at Bidston to proceed onto the Merseyrail electric network. Network Rail proposed using dual battery powered/3rd rail pickup rolling stock without full electrification of the 27 mile long line, providing a cheaper method of increasing connectivity into the electrified underground sections of the Birkenhead and Liverpool Merseyrail Wirral Line.
