ABSTRACT:
An electrical power source, either AC or DC, lead acid battery rejuvenator and charger circuit switchable between rejuvenator and charger modes of operation. For the rejuvenator mode of operation a rejuvenator pulse signal generating circuit supplies voltage in the form of fast rise voltage pulses peaking at a voltage necessary to cause battery plate saturation that is 1:1 to 1:3 times the theoretical battery cell voltage. This is accomplished by use of very short duration pulses in the order of 5 micro seconds or less time width wise with extremely fast rise time in the order of 5 mega volts per second rise time with these pulses occurring in approximately the 2,000 to 10,000 times per second frequency range. The transfer of electrons between metal electrode and ions in battery lead acid solution is not instantaneous, and that therefore with the fast rise time pulse rising to 1:1 to 1:3 times battery cell voltage the instantaneous voltage is distributed over entire battery plate surfaces and lead sulphate deposits that have occurred on battery plate surfaces will be released, either going back into the solution or broken up.
