Abstract
"IMPROVEMENTS IN THE OBJECT OF THE MAIN PATENT No. 403,337, relating to: PERFECTED BATTERY CHARGER", characterized by the fact that to determine if it is a battery with a voltage lower than that applied by the charger, the selection is made by intensity and not tension, as was done in the Main Patent, to which end an intensity transformer is inserted in the circuit of the charger, interposed in the secondary circuit of the transformer from the charger to the general rectifier, with a voltage appearing in the secondary of the cited current transformer, which rectified by an auxiliary rectifier and filtered by a capacitor, makes the signal appear in a transistor that closes the circuit of the battery charging relay, switching the 6 Volt circuit of the secondary of the general transformer.
