Abstract
A rejuvenator for lead acid batteries powered by a multi-solar cell unit and/or a rectified a.c. source, the output of which is applied to a capacitor. The output of the capacitor is in turn connected across the primary of a transformer. A switching circuit connects and disconnects the primary coil to and from the capacitor to produce in the secondary coil of the transformer a fast rise time current pulse for application to a battery. A positive temperature coefficient resistor is connected in series with an output terminal of the rejuvenator to protect the rejuvenator components in the event the output terminals, through accident or mistake, are connected to battery terminals of opposite polarity.
