battery charger , I like this, why u don't???

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.
