12V lead acid battery charger by LM317K

Today a close friend visits tell want Dry cell lead acid battery charger circuit 12V 7. 5hA sizes. In model to are simple and economize with. I then advise this circuit try build see. By use the integrated circuit voltage regulator the number is highly popular be, LM317K. This circuit has the principle is simple be heal level voltage be stable 13.

5 Volt. Because battery must use voltage tall more then charger get follow want. Which battery of a friend must use current 1A take time charging about 8 hour then will have the electric energy with full speed ahead. The detail is other, see in the circuit.
