Abstract
A circuit for use in charging a battery from a current source, such as a solar cell, includes a Zener diode, a current limiting resistor in series with the Zener diode, and a switch which shunts the resistor. In periods of high current output from the solar cell, the resistor is shunted allowing the Zener diode to limit the charging current to the battery in order to prevent damage thereto. In periods of low current output from the solar cell, the resistor limits the power consumption of the Zener diode to insure sufficient power delivery to the battery.
