9. Battery internal resistance testing system
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.
The screen displays the state of charging process.
To stop charging forcibly, press SELECT/STOP key
once. The audible sound indicates you at the end of
process.
Set discharge current on the left and final voltage
on the right. The discharge current ranges from 0.1
to 1.0A. To start the process, press START/ENTER
key for more than 3 seconds.
The screen displays the current state of discharge.
You can alter the discharge current by pressing
START/ENTER key during the process. Once you
change the current value, store it by pressing
START/ENTER button again. To stop discharging
press SELECT/STOP key once. The audible sound
indicates you at the end of process.
