1.About 18650 battery:

The minimum discharge stop voltage of 18650 battery is generally: 2.75V. Under normal circumstances, when the voltage drops to 0.875 times the rated voltage 3.24V

It should be charged, and then continue to use, the voltage will drop rapidly, there may be over-discharge and damage, affecting the life. Recommended discharge termination

The voltage is set to 3.5V

The charging voltage is generally: 4.20V-4.3V/4.35V.

2.Measurement time calculation:

Assuming that the battery capacity is 2000mAH, the discharge current of this tester is about 500mAH, 2000:500=4, and the measurement time is about 4 hours about.

How to use factory default:

1. The battery under test should be fully charged first

2. Connect the positive pole of the battery under test to the positive input, and the negative pole to the negative pole of the input, do not connect reversely reverse connection with load may damage the circuit! Connect the load to the output positive pole and the output negative pole, and connect the working power supply to the micro USB of the tester do not use the desktop or notebook USB power supply, and the battery voltage will be displayed at this time.

3. To start the test directly, you only need to press the OK button, the tester can automatically formulate the appropriate termination voltage according to the fully charged voltage of the battery, and the test will start after flashing for 3 times. Press the + or – button to modify in the display state, the termination voltage is displayed as the beginning of P, the back represents the voltage value, and the resolution is 0.1V. After setting, press OK to start the test

4. After the test starts, the tester will turn on the electronic switch that controls the load, and the data display during the test will display in turn among the discharge capacity Ah, the current discharge current A and the battery voltage V. Press the button to quickly switch the display content. When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the displayed data stays on the capacity Ah and flashes rapidly together with the corresponding indicator light. The displayed capacity at this time is the actual battery capacity. Discharge capacity, press OK to stop flashing and make the data display stably, press the OK button again to restore the power-on state to replace the battery and test the next section

Supplement: During the test, you can press the button + to exit the current test and keep the discharged data, and the tester returns to the voltage display state. At this time, the + and – buttons are allowed to modify the termination voltage and press OK Continue to start the test; or you can exit the current test and clear the discharged data by pressing the – button.

Advanced function settings:

In the case of no power supply, keep pressing the OK button and turn on the microUSB power supply, the tester enters the function setting, there are two settings, use the + – button to modify and the OK button to enter the next item and save quit:

Setting item 1: The automatic voltage identification function AUon/AUoF means enable/disable. Please manually set the termination voltage after it is disabled, and the value of each setting will be automatically saved at the same time.

Setting item 2: Automatic rotation display function ALon/ALoF means enable/disable. After disable, the display content will not be automatically switched during the test, but can only be switched manually

Error code and meaning:

Err1: The battery voltage is higher than 15V

Err2: The battery voltage is lower than the set termination voltage

Err3: The battery cannot withstand the load discharge current or the internal resistance of the line is too large

Err4: The current is too large the current exceeds 3.1A

Err5: Improper use or wiring error has caused the device to burn out and cannot be used current sampling or control switch MOS burnt

Precautions:

1. If the battery is reversely connected, when the load is turned on and the load current is large about >0.8A, the circuit switch tube may be damaged

2. The factory has been calibrated and tested one by one, and it is designed with a secondary calibration function

3. In order to improve the accuracy of voltage measurement, this circuit has specially designed a DC bias. When the terminal is not connected to anything, a small voltage will be displayed, which does not affect the actual measurement. If you short-circuit the input terminal it must be 0V at this time It will display 0. If you want to understand the principle, you can refer to the superposition theorem in electrical engineering.
