Electrical energy has become a necessity in almost all aspects, especially in the automotive sector because it has an important role in electronic systems and instruments. Batteries are a source of electrical storage energy needed to blame motor and electronic machines, with different shapes and capacities. At this time the battery has problems with charging the battery because the electric charge in the cell is reduced which takes a long time so it requires fast and efficient automatic charging. The battery charger circuit uses a power supply to reduce the 220 volts AC voltage to convert it to 19 volts DC and a step-down setting of 5 Ampere 12 Volt to enter the battery with the time needed under 5 hours of charging time with a difference of 20% battery capacity and 50% difference in 1 hour of battery charging.
