Depth of Discharge (DOD) A battery’s lifetime is highly dependent on the DOD. The DOD indicates the percentage of the battery that has been discharged relative to the battery’s overall capacity. Deep discharge reduces the battery’s cycle life, as shown in Fig. 1. Also, overcharging can cause unstable conditions.
Starved-electrolyte sealed-lead batteries obtain superior performance in deep discharge through elimination of excess electrolyte which increases the proportion of the battery's weight devoted to other active materials. The result is energy densities which give good performance in deep cycle applications.
The ability of lead–acid batteries to recover from a very deep discharge is something that depends on the exact nature of the battery, as grid alloy type, additives, etc. will affect all the previous problems of sulfation, dendrites, and passivation.
Battery Discharge Characteristics The battery voltage near the end of useful discharge is determined by the lowest capacity cell in the battery. The knee of the discharge characteristic is sharper than that of the individual cells and once the lowest cell is totally expended, the battery voltage drops rapidly.
Deep discharge depth increases BESS energy consumption, which can ensure immediate revenue, but accelerates battery aging and increases battery aging costs. The proposed BESS management system considers time-of-use tariffs, supply deviations, and demand variability to minimize the total cost while preventing battery aging.
The knee of the discharge characteristic is sharper than that of the individual cells and once the lowest cell is totally expended, the battery voltage drops rapidly. Leaving the battery connected to a load after discharge should be avoided to enable the battery to provide its full cycle life and charge capabilities.

Careful selection of the battery type and the recharging conditions in a PV system can give more or less full recovery of a lead–acid battery from a deep discharge, even if the battery has been in a deeply discharged condition for some weeks [3]. However, use of an inappropriate battery type, or an inappropriate means of PV recharging from such a condition, can result in total battery …
