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.

In this work, the main objective is to investigate the effect of high constant charging current rates on energy efficiency in lead acid batteries, extending the current range to 8A from 5A already reported in literature.
The lead-acid batteries provide the best value for power and energy per kilowatt-hour; have the longest life cycle and a large environmental advantage in that they recycled at extraordinarily high
Sealed Lead Acid The first sealed, or maintenance-free, lead acid emerge in the mid-1970s. The engineers argued that the term "sealed lead acid " is a misnomer because no lead acid battery can be totally sealed. This is true and battery designers added a valve to control venting of gases during stressful charge and rapid discharge.Rather than submerging the plate s in a liquid, the
Constant current discharge curves for a 550 Ah lead acid battery at different discharge rates, with a limiting voltage of 1.85V per cell (Mack, 1979). Longer discharge times give higher battery capacities.
The internal characteristics of lead-acid batteries exhibit a relatively higher self-discharge rate compared with some other battery chemistries. For instance, the self-discharge rate of lead–acid batteries is affected by factors such as temperature and battery age. High temperatures accelerate the self-discharge process. As a result, they

Discussions The charging and discharging of lead acid batteries permits the storing and removal of energy from the device, the way this energy is stored or removed plays a vital part in the efficiency of the process in connection with the age of the device.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].
Given the fact that for lead acid batteries, the electrodes are dipped inside the electrolyte, a change in the temperature of the electrolyte will easily be noticed on the negative plate since the anode is made up of metallic lead which is a good conductor of thermal energy.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.
Therefore, a tradeoff magnitude of charging current and health of battery will have to be found by future charge controller designers in order to safely increase charging current while protecting the battery from thermal run away. The paper also shows that the age of the battery plays a vital role in charge/discharge characteristics of batteries.
