Recognize the strength of the battery and learn how to live with its weakness
Nature offers many ways to produce power. Most result through combustion, mechanical movement and photosynthesis as in a solar cell. Energy generation of the battery occurs by an electrochemical reaction between two metals of different affinities. In 1800, inventor Alessandro Volta discovered that the voltage potential became stronger the farther apart the affinity numbers moved. When exposed to acids, a voltage develops between the metals as part of ion transfer; closing the circuit induces a current.
The most simplistic manifestation of a battery is a lemon. Driving a zinc-plated nail and a copper coin into a lemon creates a voltage. This quasi battery does not deliver much power; its current delivery system is weak and any electrical load causes the voltage to collapse. The energy does not come from the lemon itself but from the chemical change in dissolving zinc into the acid or lemon juice.
