Appearance introduction:

lithium-battery-capacity-tester-battery-charge-discharge-tester-partial-discharge-tester-car-battery-repair (31)

The battery charge and discharge capacity tester's appearance introduction:

1. Power switch: If the power is suddenly cut off during the test, the test data will not be saved.

2. Display screens: Display charging and discharging parameters and discharge curve.

3. Coding switches: Rotate to adjust working mode, press to set parameters.

4. Start/Stop button: Any operation in running state must be paused first.

5. Battery positive input: 1-2-3 pin through current, 4 pin voltage detection.

6. Battery negative input: 1-2-3 pin through current, 4 pin voltage detection.

Use method：

The battery charge and discharge capacity tester using method:

1. Start up first, and then clip the battery. Press the setting knob to enter the setting page, rotate left and right to adjust the parameters, press to determine, Set the parameters correctly and save the exit.

The battery charge and discharge capacity tester's parameters that need to be set in various modes

Parameters to be set in Charging mode:

Charging End voltage: lithium titan ate 2.7-2.8V, 18650/ternary/polymer 4.1-4.2V, lithium iron phosphate 3.6-3.65V (You must set this parameter correctly and reasonably).

Charging current: set to 10-20% of the cell capacity (Please set it correctly and reasonably) It is recommended to set a current that makes the cell heat less as much as possible.

Judging full current: that is when the charging current is less than this value, it is judged to be fully charged. It is recommended that the battery cell below 5Ah be set to 0.2A, the battery cell of 5-50Ah should be set to 0.5A, and the battery cell above 50Ah should be set to 0.8A.

Parameters to be set in Discharge mode:

Discharge End voltage: lithium titan ate 1.6-1.7V, 18650/ternary/polymer 2.75-2.8V, lithium iron phosphate 2.4-2.5V (You must set this parameter correctly and reasonably).

Discharge current: set to 10-50% of the cell capacity (Please set it correctly and reasonably)

It is recommended to set a current that makes the cell heat less as much as possible.

Parameters to be set in Cycle mode:

Charge and discharge mode parameters need to be set simultaneously

Keep voltage: The cut-off voltage of the last charge in cyclic mode ,can be the same as the cut-off voltage of the charge or discharge.

Resting time: In cycle mode, after the battery is fully filled or discharged (let the battery cool down for a period of time), usually set for 5 minutes.

The battery charge and discharge capacity tester's cycle: Max 5 times,

1 time (charge-discharge-charge),

2 times (charge-discharge-charge-discharge-charge),

3 times (charge-discharge-charge-discharge-charge-discharge-charge).

Parameters to be set in Voltage balancing mode:

Discharge End voltage: How many volts do you plan to balance the cell voltage to?

This value must be higher than 10mv than the battery voltage.

Discharge current setting reference: Less than 10% of the cell capacity is recommended.

End current: It is recommended to set it to 0.01A.

2．Return to the home page, rotate the setting button to the left or right to the working state, and press again to pause.

3．After waiting for the test to end, the result page will automatically pop up (press any button to stop the alarm sound) and record it manually. Test the results, and then test the next battery.

The battery charge and discharge capacity tester's test results: 1 indicates the first cycle, the AH/WH/min of charge and discharge respectively. Press the start / stop button further to show the results and curve of each step in turn.

The yellow numbers represent the voltage axis, and the yellow curve represents the voltage curve.

Green numbers represent the current axis, green numbers represent the current curve.

When the battery performance is good, the voltage and current should be a relatively smooth curve. When the voltage and current curve rises and falls sharply, it may be that there is a pause during the test or the charging and discharging current is too large. Or the internal resistance of the battery is too large and it is close to being scrapped。

If the test result is empty, the working step is less than 2 minutes, so the data will not be recorded.

Precautions：

The battery charge and discharge capacity tester’s clamp using methods

1. Both the large and small crocodile clamps must be clamped on the battery pole lugs!

2. The contact area between the large crocodile clip and the pole ear should be large enough, and it is prohibited to clip it onto screws/nickel plates/wires, otherwise it will cause abnormal interruption of the testing process!

3. The small crocodile clip must be clamped at the bottom of the battery ear, otherwise it may cause inaccurate capacity testing!
