Abstract:
A method for charging a battery having a fully charged capacity of C mah (millie-ampere-hour) where C is a real number comprising:(a) charging said battery by a first constant charging current C1 amperes over a first pulse-period T1 seconds wherein C1=M1*C and M1 and T1 are a real numbers and M1 is greater than 1.0, followed by charging said battery with a second constant charging current C2 ampere over a second pulsed-period T2 seconds wherein C2=M2*C and M2 and T2 are real numbers and M2 is greater than 1.0 and smaller than M1;(b) repeating step (a) over a first charge cycle of TCC1 minutes wherein TCC1 is a real number for rapidly charging said battery to a significant percentage of said fully capacity C.
