9. BATTERY INTERNAL RESISTANCE TESTING PROGRAM
The screen displays the status of the charging process.
To force the charging process to stop, press the
BATT TYPE/
STOP
button once. The audible sound indicates the end of the
process.
Lithium battery internal resistance is one of the important index about battery discharge
capacity and efficiency. We can know battery performance and the matching of each
battery by getting the battery resistance value. The lithium battery internal resistance value
tested by this charger is relative(not absolute), which is tested under the testing voltage.
But it can also know the battery performance and matching through the relative value. If
you want more battery performance comparison, you had better put them under the same
voltage to detect. For example, to compare two 3-cells batteries, you should ensure that the
total voltage is consistent. Testing in the single voltage of 4.20V, the test data is smaller the
performance better and the data more close to the battery the better matching nature.
Set the charging current on the left and the final battery voltage
on the right. The discharging current is between 0.1 and 2.0A.
To start the discharging process press the
START/ENTER
button
for more than 3 seconds.
The screen displays the current state of discharge. You can
modify the discharge current by pressing
START/ENTER
button
during the process. Once you change the current value, store it
by pressing
START/ENTER
button again.
To stop discharging press
BATT TYPE/STOP
button once. The
audible sound indicates you at the end of process.
