Comparison of internal resistance test accuracy：

The product uses the DC 2-wire method to test the internal resistance of the battery. When the battery is fully charged, the numerical accuracy is high. The test results are used for reference and comparison between the batteries d in the same batch. For those with high internal resistance accuracy requirements, please use a professional internal resistance instrument using the 4-wire AC method to test.

Test prince：

The DC impedance is that according to the physical formula R=V/I, the test equipment forces the battery to p a large constant DC current usually a large current of 10A-80A is used at present in a short time usually 2-3 seconds, measures the voltage at both ends of the battery at this time, and calates the current internal resistance of the battery according to the formula.

Capacity test accuracy reference：

The test results of five LGABB4 18650 batteries with a nominal capacity of 2600mAh in AUTO mode are as follows

How to use：

1、 Measuring internal resistance
The product uses the DC 2-wire method to test the internal resistance of the battery. When the battery is fully charged, the numerical accuracy is high. The test results are used for reference and comparison between the batteries d in the same batch. For those with high internal resistance accuracy requirements, please use a professional internal resistance instrument using the 4-wire method to test.

Test method：

Wait a few seconds after installing the battery, read the battery data, and the battery voltage and internal resistance s will be displayed. There will be a delay in data loading during battery loading and unloading, and the data will be checked after it is stable.

The circuit is disconnected when no battery is installed, and the resistance value is infinite

The circuit is formed after installing the battery, with an internal resistance of 31m

Reminder：

*High accuracy of internal resistance measurement when the battery is fully charged
*When the voltage is insufficient, the internal resistance display may have an excessive value. Please reinstall the battery for measurement after the battery is fully charged
*The internal resistance of single battery is different, and the actual measurement results shall prevail
*There is line resistance when using the extension wire to test the battery, and the error will increase

2. Setup method：

2.1. Clithe "Menu/M" key to switch menu options

2.2, Mode Menu: Clithe“Adjust/S” on to switch Mode

2.3. Stop discharge voltage: cli"Adjust/S" to switch the stop discharge voltage, and the adjustment range is 2.5V~3.5V,
The stop voltage is invalid for "charging mode".

2.4. Number of cycles: cli"Adjust/S" to set the number of cycles. The cycle is only valid in "Auto Mode"
Invalid number of cycles in "charge mode" and "discharge mode"

3. Run/Stop：

Clithe "Start stop/R/S" on to Run or Stop the program

The program is not running
"STA:STOP"

Run charging procedure
"STA:CHG"

Run discharge procedure
"STA:DSG"

End of program operation
"STA: END"

"STA:EDN"only means that the program has completed its operation. If the conditions of the current link cannot be met during the program operation, it will skip to the next link until it is completed, and the program will stop running!


High temperature protection
"STA:ERR"

"STA: ERR" means that the high temperature protection program is triered and the charging and discharging program stops running. The protection may be triered due to the abnormal operation of the cooling fan. It is necessary to chethe cooling fan, remove the cooling fault, and then rerun the program.

4、 Switch s:

cli"Pageway/CHN" to switch s, view and set s

5. Charging：

5.1. Connect DC5V power supply. The charging mode must be connected with two 5V power supplies.

5.2 Adjustment mode: MODE:CHG filling battery

5.3. Cli"Start stop/R/S" to run the program. The program starts, indicating the "STA:CHG". The charging process only records the time, capacity and energy. After charging, the program stops running, indicating the state: "STA:END".

Use 5V/4A power supply to charge four batteries at the same time. Refer to the measured charging time:
One way: 2084mAh charging, 3 hours, 16 minutes, 53 seconds

6. Battery capacity measurement:

6.1 the battery capacity can be measured only after the discharge is completed:


6.2. Adjustment mode: "MODE: SDG", fill the battery to the battery holder

6.3. Set the required stop discharge voltage, taking 2.7V as an example


The battery has power voltage drop under load, and the voltage drop is the actual voltage that triers the stop

6.4. Cli"Start stop/R/S" to run the program. The program starts, indicating the state: discharge. Record the time, capacity and energy during discharge. After charging, the program stops running, indicating the state: STA: END.


The battery is measured with a stop voltage of 2.7V, and the measured discharge time is as follows:
One way: discharge 2231mAh, taking 2 hours, 24 minutes and 25 seconds

7. Battery capacity separation and running cycle: "MODE: AUTO" mode operation procedure

7.1. Connected to 2-circuit DC5V power supply

7.2、Adjust the mode "MODE: AUTO" and fill the battery to the battery holder

7.3、Set the stop discharge voltage

7.4、Set the number of cycles

7.5. Cli"/R/S" to run the program: the program starts, indicating that the status "STA:CHG" represents the current running charging program, charging process records time, does not measure capacity and energy; Automatically switch to discharge after charging, indicating that the state "STA:DSG" represents the current running discharge program, time, capacity and energy during the discharge process; Switch to charging after discharging, indicating the state: charging, number of cycles = 1, the program ends running after charging, indicates that the state "STA:END" cycle number is greater than 1, enters the discharging mode again after charging, after entering the discharging mode, time accumulation calation, capacity and energy re-measurement, charging and discharging cycle until the cycle is completed, the program ends, the battery is full, indicating the state: STA:END.

*Actual charging time reference:
Discharged battery, automatic mode cycle 1 test: test capacity 2608mAh, time consuming: 9 hours, 59 minutes, 26 seconds

*When the cycle is greater than 1, capacity metering only records the last discharge capacity, non-average capacity

* Capacity, energy, and time data are cleared automatically when shutting down or switching modes
