High speed sample rate negative delta voltage and zero delta voltage auto-detect cut off circuit with MOSFET control for peak detection. Pulsation charge method to prevent overcharge and overheat. Input voltage allows 100V to 240V from Power Supply, or 12V to 13.8V DC; Can charge 4 - 8 cells of 4.8V to 9.6V. 3 modes of Fast Charging, Slow Charging and Fuzzy Logic Charge, also has Discharge function. Allows to change the charging current by the DIAL LOG. User selectable charging mode for Ni-CD and Ni-MH battery.

One of the best all around chargers we have tested
