The memory effect of MH Ni battery was investigated. The depth of discharge, discharge rate and cycle number influence the memory effect greatly. A few completely full charge/discharge cycles could eliminate it. The existence of the memory effect had nothing to do with zinc element. During the course of life cycling at low DOD (degree of discharge),the smaller the discharge current was, the lower was the maximum charge voltage. In addition, discharge voltage and discharge capacity drop fast at the beginning, gradually leveled off at about a value. If the discharge current was increased, the discharge capacity was obviously less than the stabilized value and maximum charge voltage was also changed suddenly. At last, the cause of the memory effect is discussed, and tentative recommendations to eliminate or mitigate the appearance of the memory effect phenomena are given.
