ABSTRACT:
A control circuit for safe charging a rechargeable battery comprising a forced short-circuit switch, a safety switch, an automatic change switch, a first rectification circuit, a second rectification circuit, a reverse-polarity detection circuit, a charging-signal output circuit, an oscillation circuit, and a condition-indicating signal assembly. Power supply can be provided from a conventional charging device or a spare battery. During the charging operations, the reverse-polarity detection circuit is used for detecting the correct polarity connection; when reverse polarity was connected, the automatic change switch will correct the polarity by indication the occupance of such condition with the indicating lamps in the condition-indicating signal assembly so as to provide a smooth and safe battery recharging.
