ABSTRACT:
A battery rejuvenator circuit for use in conjunction with automatic start/stop battery generators. The rejuvenator circuit generates a positive voltage pulse train (characterized by a fast rise time spike followed by a non-uniform hump-shaped trail-off) that is combined with a DC charging current output by the charger. Operation of the rejuvenator circuit is controlled by a start-up delay circuit and a disconnect circuit. The start-up delay circuit senses the connection to a battery and delays for a predetermined time period to allow charging to begin before activating the rejuvenation circuit. The disconnect circuit senses the disconnection of the charger from the battery and deactivates the rejuvenation circuit.
