FQA

FQA 1. What is the measurement principle of this tester?

The battery will gradually be aged with an increase in time. The main reason is that it can no longer generate some effectively chemical reaction because of the aging of the surface of the battery plate. International Electric and Electronic Engineer Association(IEEE) formally looks the Conductivity Test as one of the standards of checking lead-acid storage batteries. It points out from IEEE standard 1118-1996 that: Conductivity Test is used to test AC current generated by putting the known frequency and amplitude AC signal to both sides of the battery. AC conductivity value is the ratio of AC current signal which keeps the same phase with AC voltage and the AC voltage. This tester is designed from this principle actually.

FQA 2. Is the result affected by the installation of negative current for the vehicle?

All the negative currency will affect the result. Therefore please remove the negative currency before checking, to achieve the accurate data.

FQA 3. Can this tester predict when the battery goes down?

The internal resistance of the sealed lead-acid battery is complicated. It is generated by ohm internal resistance, concentration polarization internal resistance, chemical reactions internal resistance and interference effect caused by double capacitance’s charging. The ingredient of internal resistance and its relative content will change with different test methods and different test moments, which can lead to different tested values of the internal resistance. And there is no strict relationship between internal resistance (or conductance) and capacitance of the sealed lead-acid battery. So it is impossible to predict the life of battery according to a single battery’s internal resistance. But it can be predicted the life of the battery will be over soon from the sudden increase of its internal resistance and decrease of its conductance.

FQA 4.Is the CCA value tested by this tester correct?

CCA is considered as a control standard with the produce of the battery. According to the accumulated records, the tested value of a new battery is 10-15% higher than the standard value, and along with consuming the battery, the value is getting close to standard, even lower afterward.

FQA 5.What is the difference between the method used by this tester and the load test method?

The load test method: According to the physical formula R=V/1, test equipment forcibly makes the high permanent DC ( presently 40-80A large current is available ) go through the battery shortly ( about 2-3 seconds). And then the tested voltage of the battery can be used to figure out the internal resistance by the formula.
