How rechargeable batteries, charging, and discharging cycles work
The Discharge of the lead-acid battery causes the formation of lead sulfate (PbSO 4) crystals at both the positive electrode (cathode) and the negative electrode (anode), and release electrons due to the change in valence charge of the lead. This formation of lead sulfate uses sulfate from sulfuric acid which is an electrolyte in the battery.

Lead–Acid Batteries
Finally, at 30% depth of discharge, a lead–acid battery experiences fairly constant capacity, around 100% of the initial for most of the lifetime. Because this is very shallow discharge mode, a battery lasts much longer than the nominal capacity and can reach over 1000 cycles. When it finally reaches its end of life, the available capacity ...
