The Nitecore SC4 is a four bay charger with a total output of 6A. The charger is compatible with a huge range of batteries and has been optimised for IMR cells.
Per bay the maximum charging current is 3A, providing extremely fast and efficient charging. As an example, it would only take 55 minutes to charge a 3500mAh 18650 IMR battery to 80%.
The SC4 charger features an LCD screen with MVA technology to display real time information on the charging status. Press the 'V' button on the charger to display battery status, charging status, internal resistance, charging current and charging time. For multiple charging demands, the charging modes are manually selectable. To do this, press and hold the 'C' button to choose charging voltage (3.7V/4.2V/4.3V) and charging current (300mA-3000mA).
The smart charger automatically detects the battery type and capacity when inserted, in order to select the appropriate charging current. The batteries in bays one and two can be selected to charge in priority.
The Nitecore SC4 is able to recover depleted IMR batteries. Upon insertion of a 0V IMR battery, the LCD display will blink to indicate that it is non-rechargeable. In this instance, press the 'C' and 'V' button simultaneously to enter recover mode. If the battery fails to be recovered after serveral attempts, Nitecore recommends that the battery is abandoned.
The SC4 charger is compatible with the following Li-ion/IMR/LiFePO4 batteries: 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340 (RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 22500, 22650, 25500, 26500, 26650. In addition, the following NiMH (NiCd) cells can be used: AA, AAA, AAAA, C and D.
