The following graph shows the evolution of battery function as number of cycles and depth of discharge for a shallow-cycle lead acid battery. A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%.
This is the primary factor that limits battery lifetime. Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated discharges to 20 % and have cycle lifetimes of ∼2000, which corresponds to about five years. Battery capacity is reported in amp-hours (Ah) at a given discharge rate.
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. The dependence of the battery on the battery state of charge is shown in the figure below.
X 6.6 x 8.9 (305 x 168 x 227) If we discharge the battery more slowly, say at a current of C/10, then we might expect that the battery would run longer (10 hours) before becoming discharged. In practice, the relationship between battery capacity and discharge current is not linear, and less energy is recovered at faster discharge rates.
One disadvantage of lead acid batteries is usable capacity decre ase when hig h power is discharged. For example, if a battery is discharged in one hour, only about 50 % to 70 % of the rated capacity i s available.
Lead–acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge.

Lead–acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
