The microscopic model of discharging in the case of a lead-acid battery
Szabo Levente explains a microscopic model of discharging in the case of a lead-acid battery.
consider the battery fully charged with 10 units of primary elements that have access to this area. These 10 primary elements will release a few electrons through an electrochemical reaction. We also consider that the other elements do not have access to this area and do not have any influence on these processes, only these 10 primary elements and the secondary elements by which the reactions have been caused. At the initial equilibrium state of the fully charged battery we consider the lack of any electrochemical reactions in this area.
 
When the discharge begins, the primary elements in the electrode area react with each other and as the result of these reactions secondary elements appear and electrons are released. After that, these secondary elements change places with their primary element neighbors. This process lasts a over a finite time and  is caused by the electrical field. The aim of the system is to recover the equilibrium state, because the released electrons migrate to the exterior circuit. The secondary elements resulting by the first reaction, cannot release other electrons to the electrode, they just occupy a place in this space. These secondary elements change their places with the nearest primary elements. The next step is the new reaction generated by the new primary elements in the electrode area, and then change places. This process continues until all primary elements are consumed and only secondary elements exist in the unit of this area. The end of the process corresponds to a fully discharged battery in this zone and these elements do not release other electrons to the electrode. In the charging mode the reverse reaction is produced by the secondary elements.

The timing of changing places in an ideal informatics model

For simplicity we consider that the time of a reaction is equal to the time of changing places of two elements. We neglect the external influence of other elements on
