ABSTRACT:
A circuit provides a half-wave rectified current for charging batteries from an AC source. The circuit comprises a rectifier, such as a diode, in series with the batteries and biased to conduct a first half cycle charging current from the AC source and a signal emitting and rectifying device, such as a light emitting diode (LED), biased oppositely from said rectifier, to conduct the opposite half cycle of current and adapted to emit a signal when conducting to indicate the charging process.
