The open circuit voltage of lead acid battery indicates the equilibrium
voltage of the battery's main reaction. The concentration of the sulfuric acid
participated in the main reaction is the major factor influencing the open
circuit voltage.
Right after charge or discharge, the concentration of sulfuric acid inside the
plates is still changing due to the diffusion process. It takes several hours to
several days to stabilize the open circuit voltage.
The concentration of sulfuric acid in the battery is an indicator of battery
capacity. Therefore, the state of charge of the battery is available through
measuring the open circuit voltage. The relation between the battery capacity
and open circuit voltage is as follows:
3.3 Battery Self-discharge
The lead acid battery will have self-discharge reaction under open circuit
condition, in which the lead is reacts with sulfuric acid to form lead sulfate
and evolve hydrogen. The reaction is accelerated at higher temperature. The
result of self-discharge is the lowering of voltage and capacity loss.
Batteries will lose capacity due to self-discharge through packing,
transportation and storage process at various temperatures. The relation
between battery capacity and storage temperature and time is as follows:
