simple lead acid battery charger circuit design

For this simple lead acid battery charger we need a center tapped transformer (12V 0V 12V) which need to give a 5 amperes current, two diodes and one capacitor. To charge the batteries we need to connect the terminal + and - from the charger to the same terminals form accumulator. When the batteries is empty the ampere-meter connected to the devic

e will indicate a value between 1 and 3 amperes, if the batteries are charged the value which is indicated on ampere-meter is almost zero and the charger can be unplugged form accumulator.
