ABSTRACT:
A battery charge system includes an electronic polarity sensing, a charging circuit and a timer. When a battery to be charged is connected, the polarity sensing circuit automatically recognizes the polarity of the inserted battery and the drive circuit charges the battery with correct polarity current for the required period of time. The charge timing circuit indicates when charging is taking place and when the charge is finished. When the battery is removed and another battery is inserted, the device is reset and the process is repeated.
