With Max 200W power, the D-3004A can charge 4pcs Gold mount camera batteries simultaneously. The charging output is DC15-20V, 2A each channel.
LED Charging Indicators for Each Channel
The D-3004A has LED charging indicators on the front panel, display the real time capacity percentage of each channel when charging.
When the batteries will not be used for a period of time, it is recommended that keep half capacity in the batteries before storage, to ensure a good condition of the cells and prolong the battery life. So the CH-1 channel of D-3004A can discharge the battery. Mount the battery on CH-1, and press “OPTIMIZE” button on the front panel, the battery will start to discharge at average 1A current.
Li-ion charging follows a two-period approach. The first period is constant-current. The battery is charged at the maximum charging rate. When the battery reaches a specified set-point voltage, charging circuits switch to the second period: the constant-voltage period. The charging circuit will provide only enough current to maintain the voltage, to prevent the battery from over charging.
