A "charge cycle" is ambiguous. We usually talk about a "full cycle" or a "charge/discharge cycle". That is defined as starting from a full battery, discharging it fully over the rated time (typically 20 hours for lead acid), and

The effect of fast charging and equalization on the reliability and

Capacity reduction (degradation) of lead-acid battery over time is a regular occurrence. This is because a battery is typically designed to be cycled between 20 and 80 % SOC. Close observation points out a similar trend of voltage rise with every fast charge and discharge cycle. An increase in voltage indicates an increase in the resistance

OverviewSulfation and desulfationHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplications

Lead–acid batteries lose the ability to accept a charge when discharged for too long due to sulfation, the crystallization of lead sulfate. They generate electricity through a double sulfate chemical reaction. Lead and lead dioxide, the active materials on the battery''s plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery rech
