By use of experimental testing methodology, termination voltage ripples, capacitance, cycle-lifetime and leakage current have been tested and analyzed. By comparing both theoretical and experimental results, the reason for partial characteristics variation of super-capacitors internal structure has been investigated and discussed. These chievements are essential for some critical applications of super-capacitors. Keyword：super-capacitor, constant-current charging, new energy
