Abstract

A charge control circuit for regulating the current applied to a secondary battery utilized as a power supply in an electronic instrument is provided. The secondary battery is adapted to be charged to a predetermined voltage level in response to a charging current being applied thereto. A charging current is produced by a charging device, such as a solar battery. Voltage regulating circuitry is disposed intermediate the charging device and the secondary battery for detecting the voltage level of the secondary battery and, in response thereto, selectively regulating the application of the charging current to the voltage supply.
