An alternator control system for controlled charging of a secondary battery such as a lead-acid battery, the invention allows manual selection of alternator output current. The control system of the invention is connected to the alternator field terminal in parallel to the voltage regulator. The selected alternator output current is essentially constant to allow estimation of the time necessary to charge a given number of ampere hours. The present control system also incorporates a voltage sensing cutoff circuit which disconnects the control system from the alternator when the battery has reached full charge, when the selected charging current becomes excessive as the battery approaches full charge, or when a charging current is selected which is excessive for the capacity of a given battery.
