Specification:

Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value is switched by shifting the decimal point, when it is less than 10Ah will display X.XXX, up to 10Ah or more will display XX.XX, and so on.

Discharge voltage: 1.00V-15.00V, 0.01V resolutionTermination voltage range: 0.5-11.0VSupported current: Maximum 3.000A, 0.001A resolutionMaximum voltage measurement error: 1% + 0.02V

(1) The battery under test is fully charged first;

(2) Connect the positive pole of the tested battery to the input positive pole, the negative pole to the input negative pole, and give the tester micro USB through the working power;

(3) Press the “OK” button to press the “+” or “-” to set the termination voltage in the battery voltage display state. After setting, press “OK” to start the test.

(4)When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the display data stays on the capacity (Ah) and flashes rapidly with the corresponding indicator light. The capacity displayed at this time is the actual discharge capacity of the battery. Move "OK" to terminate the flashing to make the data display stably. Press the "OK" button again to return to the power-on state. You can replace the battery test in the next section.
