1. A battery rejuvenator, comprising:

  • a switching circuit for generating a pulse train signal having predetermined current and voltage signal characteristics, the predetermined current signal characteristic comprising for each pulse in the pulse train signal a substantially linear rise in current from a base current level at a first current rate followed by a substantially linear decay in current to the base current level at a second current rate less than the first rate, and the predetermined voltage signal characteristic comprising for each pulse in the pulse train signal a substantially linear rise in voltage from a base voltage level at a first voltage rate, followed by a substantially linear decay in voltage at a second voltage rate less than the first voltage rate, and then followed by an exponential decay in voltage to the base voltage level; and

    means for connecting the generated pulse train signal having the predetermined current and voltage signal characteristics to a pair of terminals for a battery to remove or inhibit sulfate deposit growth.
