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-cell 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.
8.2 Discharging Pb battery
Set discharge current on the left and final voltage on
the right. The discharge current ranges from 0.1 to
2.0A.
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
Batt Type/Stop
key once.
The audible sound indicates you at the end of process.
Interface of the internal resistance testing.
The screen displays the state of charging process.
To stop charging forcibly, press Batt type/Stop key
once. The audible sound indicates you the end of the
process.
