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.
This battery type is specifically designed to pollute less (see environmentally friendly claims) due to the lesser use or the absence of heavy metals. Water-activated batteries have been used in radiosondes that shouldn't contain heavy metals since they regularly fall to the ground or ocean surface, and indefinitely remain there.
The penny battery experiment is common during electrochemistry units in an educational setting. Each cell in a penny battery can produce up to 0.8 volt, and many can be stacked together to produce higher voltages. Since the battery is a wet cell, the effectiveness will be reduced when the electrolyte evaporates.

Using a multimeter set on the 9.99 volts DC max scale, and with nothing else connected to the battery (that is, when measuring the "open circuit" battery voltage), the meter reads about 2.8 volts, or about 0.7 volts per cell. It is not a very good battery; I measure a short circuit current of about 6 milliamperes.

Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
