What is a "charge cycle" of a lead-acid battery?

It seems that my 200 Ah battery pack stays at 100% state of charge (SoC) most of the time. And when there is a short (a couple of minutes) power cut, it goes down from 100% to 99% (or worse, 98%). When the power is back on, it goes back to 100%. Does this count as 0.01 of a charge cycle?

Battery Charging and Discharging Parameters

For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery.

Battery SOC: How Do We Estimate "State Of Charge" Of Batteries?

A lead acid battery. It involves using a sensor that measures changes in the weight of the active chemicals present in the battery as it discharges. As the charge stored in the battery is used up, the concentration of sulfuric acid (an active electrolyte in the battery) decreases, which proportionately reduces the specific gravity of
