This Pb137 charger circuit electronic project can be used for charging lead acid battery. Using the PB137 voltage regulator circuit and some other electronic parts can be designed a charger which is capable to provide 1.5A at 13.7 volts. PB137 is designed by ST Microelectronics in a TO-220 package and is a complete constant voltage battery charger with reverse polarity protection , over temperature protection , over voltage protection and short circuit protection .
