The discharge current is shown on the left and
voltage of the battery pack on the right. The
discharge current ranges from 0.1A to 1.0A. You
can alter the parameters by pressing Start/Enter.
Once the correct values have been input, press
Start/Enter again to store the values. To start the
discharging process, hold Start/Enter for 3
seconds.
Select the interface for Internal Resistance
Testing. Press Start/Enter to enter into it.
Press INC to check the total IR data of the battery
pack. Press INC again to view the data of
individual cells. This screen shows an example of
what a reading of a faulty cell may look like.
This screen shows the present position of the
discharging process. To stop discharging press
Batt Type/Stop once.
This screen shows the present position of the
charging process. To stop charging press Batt
Type/Stop once.

Lithium battery internal resistance (IR) is an important measure of battery discharge,
capacity and efficiency. We can discover the battery performance and the matching
of each cell by getting the battery resistance value. The Lithium battery IR value
tested by this charger is relative (not absolute). Battery packs are subject to
assembly which will incur wires of different thickness, soldered connections and
connectors, meaning that the IR readings can and will vary. It is important to always
test fully charged packs. Cells should be close in value; bad or damaged cells will be
immediately visible as the difference will be large.
