Not all chargers lead acid batteries available on the market use appropriate methods of battery power, resulting in a considerable reduction its useful life. Therefore, developing a battery charger Lead-Acid using appropriate methods of battery life is not a simple task. Thus, this study is based on the dedicated integrated circuit from Texas Instruments BQ2031, utilizing three different methods of loading, and the microcontroller PIC16F877A properly monitor and for charging a lead acid battery, increasing its useful life. The research results were fabricated and tested control, monitoring and power circuits.
