DUOYI 12V/24V Battery Tester Lead-acid Battery Analyzer Diagnostic Tool CCA 100-1700
DY2015 series battery storage testers are used for activated style lead- acid storage battery, along with checking the following conditions of the battery, starting up, charging, and electrical loading. DY2015B and DY2015C are also designed with the function report printing. With great design, easy operation, precise reading, complete functions, this tester supply the readings by a large LCD and hints by sound and light when testing. Precise circuit and strong digital processing unit make it complete collection of a series of complicated data and figure out every test data, which availably by 4-wire Kelvin test connection. Besides it strengthens input protection inside , in order to prevent such situations as polar reversal connection , over-high voltage input, poor contact of the test clamps and so on. That makes sure safer and more convenient when testing.This tester is the best tool for battery sales, vehicle repair and condition check of all kinds of lead-acid batteries that used in equipment system associated with lead-acid battery. |
Q&A： What is the measurement principle of this tester? The battery will gradually aging with increase of time. The main reason is that it can no longer generate some effectively chemical reaction because of aging of the surface of the battery plate. That is why most of the batteries can longer be used mainly. International Electric and Electronic Engineer Association(IEEE)formally looks the Conductivity Test as one of the standard of checking lead acid storage battery. 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 same phase with AC voltage and the AC voltage. This tester is designed from this principle actually. |
| Can it be affected by the installation of negative current inside the vehicle? All the negative currency will affect the result. Therefor please remove the negative currency prior to checking, in order to achieve the accurate data. |
Can this tester predict when does the battery become useless? 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 method and different test moment, which can lead to different tested value 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. |
| Is the CCA value tested by this tester correct? CCA is looked as a control standard with the produce of the battery. According to the accumulated records, the tested value of new battery is 10-15% higher than the standard value, and along with consuming of the battery, the value is getting close to standard, even lower afterward. |
What is the difference between the method of this tester and the load test method? The load test method: According to the physical formula R=V/1, test equipment forcibly make the high permanent DC current ( 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. (1) Just available for large capacitance battery or storage battery. The small capacitance battery can not load 40-80A large current in 2-3 seconds. (2) When the large current going through the battery, there comes out polarization phenomenon from internal electrode, which can cause polarization internal resistance. As a result it has to be tested in a short time. Otherwise there is a large error of the internal resistance value. (3) The internal electrode will be damage generally when large current go through the battery. The method of this tester:Battery is actually equivalent to an active resistance. So we add a fixed frequency and small current to it, and then sample the voltage value. Eventually the internal resistance can be figured out after some operation such as rectificationand smoothing. |
