This study proposes a method to improve battery life: the hybrid energy storage system of super-capacitor and lead-acid battery is the key to solve these problems. Independent renewable energy systems such as wind and solar are limited by high life cycle costs.
This article examines lead-acid battery basics, including equivalent circuits, storage capacity and efficiency, and system sizing. Stand-alone systems that utilize intermittent resources such as wind and solar require a means to store the energy produced so the stored energy can then be delivered when needed and the resources are unavailable.
The resulting temperature increase depends on the amount of the released energy and on the heat capacity of the battery and its components. If the temperature of the boiling point of the electrolyte (approx. 110°C) is reached, the electrolyte evaporation begins. In valve regulated systems the evaporating water leads to a pressure buildup and finally to an activation of the

The capacity (Ah) exhibited by a lead–acid battery when discharged at a constant rate depends on a number of factors, among which are the design and construction of the cell, the cycling regime (history) to which it has been subjected, its age and maintenance and the prevailing temperature.
Therefore, the maximum open-circuit voltage that can be developed by a single lead-acid cell is 2.041 V. Negative and Positive Plate Construction Methods. The simplest method for the construction of lead-acid battery electrodes is the
Several kinds of additives have been tested for commercially available lead-acid batteries. The increase in the internal resistance of the lead-acid battery during charge-discharge cycles coincided with a decrease in the discharge capacity of the tested battery, so the internal resistance can be a good index of deterioration of the battery.

Lead Acid. The nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge. Nickel
Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds. Due to inherent sluggishness, however, lead acid does not perform well on a sustained high current discharge; the battery soon gets tired and needs a rest to recover. Some sluggishness is apparent in all batteries at

The capacity of your single battery cannot be increased from its original capacity. However, strings of batteries can be easily connected together to increase a battery banks voltage or its capacity. DO NOT CLOSE THE CIRCUIT BY CONNECTING THE LAST NEGATIVE TO THE FIRST POSITIVE WHEN MAKING PARALLEL OR SERIES PARALLEL CONNECTIONS.
The power capacity can be improved by increasing the surface area of each electrode, which means greater quantities of thinner electrode plates in the battery. Low cost, high power, and easy recyclability are among the advantages of the lead-acid batteries. One main drawback of lead-acid batteries is usable capacity decreases when high power is discharged. In addition, as
