Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.
The battery should not, therefore, be discharged below this voltage. In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge.
During the charging cycle, lead sulfate converts back into lead dioxide and spongy lead, effectively restoring the battery's energy storage capacity. Lead-acid batteries naturally lose charge over time, even when not in use.
