Why did you choose us?(1) external load capacity of the battery and other tests;

(2) Tools, single-function, by controlling the load off and get real-time integrated discharge current capacity results;

(3) Maximum support 15V 3A discharged through the discharge voltage and current, itself does not discharge;

(4) Support current through: maximum 3.000A resolution 0.001A;

(5) Automatically identify and develop appropriate battery termination voltage can also be manually adjusted

Instructions:(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.

The error code and meaning:

Err1: the battery voltage higher than 15V

Err2: the battery voltage is lower than the setting voltage termination

Err3: the battery is unable to withstand the load discharge current resistance is too large or line

Err4: the current is too large (current is more than 3.1A)
