The objective of this work is to present a proposal for automobile batteries production line on a land area of 4000 m^2 with better characteristics.. Due to the huge number of vehicles in our daily life, batteries which convert chemical energy into electric energy with low cost and high efficiency are produced. The typical new lead-acid battery contains 60 to 80 percent recycled lead and plastic. During the recycling process, a battery is separated into three distinct components. The lead is smelted and refined to be used in new batteries. The plastic case is recovered and its material cleaned, and molded into new battery cases. The used acid is even recycled for reuse. Three main stages of lead-acid battery recycling are : battery treatment , smelting and refining .
