The depth of discharge in conjunction with the battery capacity is a fundamental parameter in the design of a battery bank for a PV system, as the energy which can be extracted from the battery is found by multiplying the battery capacity by the depth of discharge. Batteries are rated either as deep-cycle or shallow-cycle.

Customer ServiceThe discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.
The end of life is usually considered when the battery capacity drops to 80% of the initial value. For most lead–acid batteries, the capacity drops to 80% between 300 and 500 cycles. Lead–acid battery cycle life is a complex function of battery depth of discharge, temperature, average state of charge, cycle frequency, charging methods, and time.
Conclusions 1. The electrochemistries of the soluble lead-acid flow battery and the static lead-acid battery are distinctly different; in the soluble lead acid battery lead is highly soluble in the electrolyte of methanesulfonic acid, while lead is a solid paste in the static lead-acid battery.
Following a large number of charge/discharge cycles, a soluble lead-acid flow battery could fail due to cell shorting caused by the growth of lead and lead dioxide deposition the negative and positive electrode, respectively.
One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.
