ABSTRACT:
In an improved charging set for the regenerative recharging of dry batteries that consists principally of a hollow insulating case (1) provided with an inner hole (13) for removably receiving standardized types of dry batteries, with mains contact pins (21, 22) for applying the charger set to nearly all standardized types of mains sockets, and of a charger rectifier circuitry, the improvement according to the invention is characterized in the charging rectifier comprising passive electric circuit elements only and no charger transformer, and simultaneously, the casing (1) being designed and shaped so as to be absolutely shock-proof by excluding access to any naked area of the inserted dry battery and all naked live contactors (30) and component parts of the charging rectifier while the mains contact pins (21, 22) and thus, the charging set are being applied to the mains for normal operation.
