Charging and preserving are major issues in the services of batteries since they are mostly connected to most applications. As many batteries are charged and recharged through their uses the maximum power and capacity of the battery slowly decreases. The phenomenon is termed aging is a particular concern in fields such as the automobile industry where efficient performance and long battery life is essential. Even when the batteries are left for a long time without using them, their performance tend to drop and the application to which they are removed from also encounter some problems. Therefore preserving these batteries when they are not in use is vital to the effective and efficient performance of these batteries. The main object of this dissertation is to solve the problem of overcharging and undercharging and undercharging of batteries and also how it can be preserved for some time. The importance of good charging is first addressed; the problems are demonstrated by experiments of charging and discharging processes. Then the technique of recharging and preservation are reviewed. To improve the methods of recharging, a dynamic scheme is developed. The balance recharging circuit can be employed during off-line or even discharging on observing that the output voltage will vary in a big range when a battery is discharged  the technique of charging can be integrated with voltage regulation on the output. The experiments used in this dissertation are carried out on lead acid batteries. Therefore, the reactions and characteristics of lead acid batteries are discussed. However, the proposed circuit is not restricted to be applied on lead acid batteries only. Experiment results confirm that theoretical analysis and manifest the effectiveness of the designed circuit.
