ABSTRACT:
A two part battery recharge method first introduces stepped charge current to the battery to restore a majority of energy to a deeply discharged battery. Thereafter, relatively low frequency periodic charge currents and discharge currents interspersed with relaxation periods are introduced to the battery to effectuate efficient energy restoral and increased cycle life of the battery.
