Operation and Setup
Internal Resistance Measurement Function
D6 Duo Pro AC/DC Dual Channel Smart Charger is equipped with a function of measuring the
cells’ internal resistance, which is only applied when conducting balanced charging. The cell
voltage should be measured and calculated within 2 to 3 minutes after the charging task has
been initiated. The battery internal resistance can slightly vary under different electric quantities
while the measured resistance value is usually relatively low as the electric quantity is large.
The charging current should be adjusted instantly as the charger measures the internal resistance
of the battery; therefore, it is normal phenomenon for acute change of current to occur during
charging.
Activation And Restoration Function Of Excessive Discharged Battery
When the charging task begins, one tenth of the setting current should be applied to activate and
restore the battery if the cell voltage is tested to be lower than the pre-charge voltage; on the
other hand, it should be adjusted to a rated voltage for charging when the cell voltage is higher
than the pre-charge voltage. This design can protect excessively discharged batteries, as well as
conduct activation and restoration.
