Conclusion:

When testing the battery, make sure that the two contacts of the positive and negative clips are in good contact to get the exact value.
Note: If the negative contacts 1 and 2 are short-circuited, there is no effect on the reading of the voltage, but the impact on the health of the test battery is very large.
