Ancel BST100 Car Battery Tester 12V Cell100-2000CCA 30-220Ah

1.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 data

(1) Only 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 a polarization phenomenon from the internal electrode, which can cause polarization internal resistance. As a result, it has to be tested in a short time. Otherwise, there will be a large error in the internal resistance value. (3) The internal electrode will be damage generally when the large current goes through the battery.

(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.
