Balance Function
The balance function is used to balance the voltage of cells and make them equal. The balance
time is related to the cell voltage difference and the target voltage. When the menu is switched
to the balance mode, the charger automatically analyzes and sets the initial balance voltage
value, and the user can freely adjust it. The charger's charging ability is much larger than the
discharge capacity; in the balance operation , selecting voltage equal or larger than the current
battery voltage usually lets you attain faster effect in balancing.
Battery Activation And Repair
After the charging task starts, if it is detected that the cell voltage is lower than the pre-charging
voltage, the cell will be activated and repaired using one tenth of the task setting current. After
the voltage becomes higher than the pre-charging voltage, the voltage will be adjusted to the set
voltage for charging. Such design can protect the over-discharged battery , activate and repair it.
About Internal Resistance Measurement
The D6 Pro AC/DC Dual Channel Smart Charger has a cell internal resistance measurement
function that is only effective when performing balanced charging tasks on the battery. About
two or three minutes after the start of the charging task, the internal resistance of the battery is
measured and calculated. The internal resistance of the battery varies with different power levels.
Generally speaking, the internal resistance measured is lower when the power is higher. When the
charger measures the internal resistance of the battery, the charging current is instantaneously
adjusted. Therefore, it is normal to find that the current is abruptly changed during the charging
process.
Due to the difference in the ways of measuring the internal resistance, the test accuracy of
internal resistance like those attained on professional measuring instruments cannot be
achieved. Therefore, the internal resistance value is only suitable for horizontal comparison
reference, such as judging the consistency of cell performance or comparing the performance
parameters of different batteries. The magnitude of the charging current has a certain influence
on the accuracy of the internal resistance measurement. A battery with a large capacity and low
internal resistance requires a large charging current to accurately measure the internal resistance.
