Test Data Descriptions of The Battery Diagnostic Tool

The FA-V311BM car battery tester and diagnostic tool supports many data. Including: voltage, rated value, measured value, internal resistance value, service life, remaining power etc. In order to make customer know more about the test data, we hereby provide more descriptions as below:

1. Battery voltage: The current voltage value of the battery measured.

2. Rated value: The nominal value on the battery. User need to input the value on battery label to tester diagnostic tool and select corresponding test standard;

3. Measured value: The current value measured and evaluated by the battery tester. It is the difference between the nominal value and the measured value; Generally, the measured value of a new battery will be close to the nominal value. The longer the battery is used, the worse the aging, and the lower the measured value will be.

4. Internal resistance: The internal discharge resistance value of the battery varies with many factors. Like brand, process, type, current temperature, and duration of use of the battery. The better the performance of the general battery, the lower the internal resistance value.

5. Service life: The value calculated based on the evaluation of the rated value. And the current state of the battery reflects the aging degree of the battery and remaining life;

6. Remaining power: The value calculated according to the current state of the battery. It indicates how much power is left in the battery. If it is full charge, it should be 100%.

For more detail please refer to the user manual enclosed with the battery diagnostic tool.
