If you do not know the capacity of the battery, there may be potential safety hazards, or there may be insufficient power, too much power, etc. However, the battery capacity tester may also have errors, so it is necessary to regularly check the battery capacity tester. , to ensure normal use. Let's take a look at how to use the battery capacity tester?

1. Connect the positive and negative poles of the output line. The positive pole of the battery capacity detector and the positive pole of the battery are connected together, and the negative stage and the negative stage of the battery are connected together. After connecting, you will hear a The beeping alarm sound, this is the prompt sound after the battery capacity detector is powered on.

2. Now press the select key to try the discharge current, and also press the select key to terminate the voltage. There are some other keys, the reset key can stop the beeping sound. Then the instrument will start to record the discharge time.

3, and then choose the discharge current, 7-14AH is 5A, 17-24AH is 10A.

4, and then test the capacity of the battery, the test is 10.5V, and then deep discharge, the voltage is 3V.

5. When the discharge stops, the beeping alarm sound will also stop. Now that we have finished the test, we can remove the battery. To record the discharge time, the calculation formula is: battery capacity=discharge current discharge time .
