The LM393 nickel-cadmium battery charger circuit of high performance-price ratio is shown as the picture,it has the following features:(1)The process of constant-current charge runs with the process of heavy current discharge.The value of current of constant-current charge is about 300mA.And the discharge current increases along with the increase of battery voltage and the value of discharge current will reach 400mA when the battery is to the full value.The charging time is 1.5 second,discharging time is 0.5 second,and take turns. When the heavy current charge is over,there is about 5mA purling current charging.(2)The detection of battery voltage works during the discharging.It is because that the voltage of charge is greater than the discharge.
