Principle

The storage of electrical energy is a significant problem of the power supply, especially since the energy of the alternating current provided in power plants can not be directly stored. Direct current can be stored by the conversion of electrical energy into chemical energy.

The appropriate device for electrical energy is called accumulator. In practice, several accumulator cells are connected in series to form a battery. Such "rechargeable batteries" are known to the pupils. This experiment illustrate the basic structure and mode of operation of a lead accumulator
