Review on different charging techniques of lead-acid batteries

For many years, several studies were made to improve conventional charging techniques of lead acid batteries. On the other hand, other studies were held to invent some new tactics that have better features. This paper is a review on different charging techniques of lead acid batteries. Some of the ways might look similar; however, they differ in performance and efficiency. When designing a charger of a battery, some parameters must be taken into consideration such as the State Of Charge (SOC), the lifetime of the battery, and the charging time. For these reasons, with the development of machines and capabilities, the old techniques were improved and their lacunas were fixed. In addition, some new methods came up from the loopholes found in this battery.
