The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.
The different contributions to the voltage drop in the lead–acid cell can be grouped in three main groups: those affecting the electrolyte resistance, those related to the material structure, electrodes and separators, and those involved in the electrochemical reactions at the double layer.
