The utilization of lead acid batteries (LABs) in engineering applications is rapidly increasing day by day. The charging time and the battery temperature are the biggest issue in almost all engineering applications. In. By considering various researches and statistical news, the curriculum of Lead acid batteries. The main component of the system is battery, which is chosen based on the properties and the behaviour with environment and temperature. One of the most important p. To obtain the proposed objectives by undergoing a detailed survey of different published journals related to effect of ambient pressure on lead acid battery and technical stuffs T. The paper was mainly focused on the performance and analyze the effect of ambient pressure on charging characteristics of lead acid battery. The charging process.
