Automotive 12V Car Battery Load Tester Battery Cranking Charging Analyzer Tool Ancel BST100 Car Battery Tester OBD2 12V Cell Cranking Charging test Diagnostic Tool 2000CCA 30-220Ah Battery System for CarIntroductionAncel BST100 battery tester is used for lead-acid starting battery, along with checking the following conditions of the battery, starting up, charging, and loading. 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. It utillizes 4-wire kelvin method to complete collection of a series of complicated data for calculating every testing data with build-in precise circuit and improved digital processor. moreover some circuit improvements including polar reversal protection, over voltage input protection, loose lead detection, ensure safety and convenience during testing. So this is the best tool in the fields of battery sales, vehicle repair and battery inspection in equipment system associated with lead-acid starting battery.Ancel BST100 function1.Identify battery status Good or Replace 2.Check Battery Capacity - Cold Cranking Amps (CCA), DIN, EN and IEC information relative to battery rating. 3.Check Internal resistance value (Ohm) 4.Display battery life in percentage (%) 5.Battery Cranking Test, load test 6.Battery Charging Test, Ripple Test 7.Support battery ripple test and review test dataBST100 12V Battery Tester Features:1.Fast and smooth running speed with STM-32 chip set hardware 2.Accurate test results, using high precision amplifier and calibrated by professional battery testing tool, BST100 reading accuracy up to 99%. 3.Wide testing range cover from CCA 100- 2000 , 3- 220 AH, best in the market. 4.Industry initiative graphical battery voltage real time monitoring, can be analysis battery data more accurate. 5.Unique battery results display in percentage and meter mode. 6.Test all automotive cranking lead acid battery, including ordinary lead acid battery, AGM flat plate battery, AGM spiral battery, and Gel battery, etc. 7.Polarity reverse connection protection, reverse connection will not damage the tester or affect the vehicle and battery. 8.Directly test the battery with loss of electricity, no need to full charge before testing. 9.Testing standards include currently the world's majority of battery standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB. 10.BST100 is used to test a wide range of 12V batteries (Starting [SLI], Deep Cycled and Marine) of Wet (Flooded), VRLA or Maintenance Free (MF), Sealed Maintenance Free (SMF), Absorption Glass Mat (AGM) and GEL EPB cellAdvantages of this method:(1) It can be used for checking almost all the batteries including low capacity battery and internal resistance of the notebook battery exclusively. (2) It will not harm the battery by using this method.BST100 Support Languages:English, French, German, Russian, Spanish, ItalianFAQ Area: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. 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. 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. 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. 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.
