The common problems

6.1 The measurement principle of the tester
As time goes on, the battery will gradually age. The main reason is that the surface of the battery plate is aging and no effective chemical reactions can be carried out. This is the main reason why most batteries can not continue to use. The International Association of Electrical and Electronic Engineers (IEEE) formally takes the conductance test method as one of the testing standards for lead-acid batteries. In IEEE standard 1118-1996, it is clearly stated that “the measurement of battery conductance is to add the
AC signal with known frequency and amplitude to both ends of the battery, and then measure the produced alternating current. AC conductance is the ratio of AC current
(that has the same phase as AC voltage) to AC voltage. This product is based on such a judgment basis and developed.

6.2 The reverse current is installed on the vehicle, will it affect the test result?
All inverse currents will affect the test results of the instrument, so please remove the reverse current to measure to ensure the accuracy of the test result.
6.3 Can this product accurately predict when the battery will fail?
The internal resistance of sealed lead-acid batteries is complex and includes ohmic internal resistance, concentration polarization internal resistance, electrochemical reaction internal resistance, and the interference effect of double-layer capacitor charging.
The composition and the relative content in the internal resistance values measured by different methods and at different times are different. So The measured internal resistance values are also different. There is no strict mathematical relationship between the internal resistance (or conductance) of sealed lead-acid batteries and the capacity of
batteries. It is impossible to predict the service life of batteries according to the internal resistance (or conductance) of a single battery. However, the sudden increase in internal
resistance or sudden decrease in conductance indicates that the battery life is about to end.

6.4 Is the CCA measured by this product correct?
CCA is a control standard for battery production. The cumulative results show that the CCA value measured by the new battery will be higher than the labeled value (10-15%). With the user’s use, the CCA value will be closer to the labeled value, and then the CCA value will be lower than the labeled value.
6.5 The difference between the product test method and the load test method:
According to the physical formula R = V / I, the test equipment allows the battery to force a large constant DC current (currently used 40A ~ 80A high current) in a short time (usually 2 ~ 3 seconds), measure the voltage at both ends of the battery, and calculate the current battery internal resistance according to the formula.
This method has obvious shortcomings:

1. Only large-capacity batteries or storage batteries can be measured, and small-capacity batteries cannot load 40A-80A high current in 2-3 seconds.
2. When the battery passes through a high current, the electrode inside the battery will polarize and produce polarization resistance. Therefore, the measuring time must be very short, otherwise, the error of the measured internal resistance is very large.
3. The large current will damage the electrodes inside the battery.
   This product measurement method: Because the battery is actually equivalent to active resistance, so we apply a fixed frequency and a fixed current (small current) to the
   battery, and then sample its voltage, after rectification, filtering and a series of processing, finally calculate the internal resistance value of the battery through the arithmetic circuit.

The advantages and disadvantages of this method:

1. Using this measurement method can measure almost all batteries, including small-capacity batteries. The internal resistance of notebook batteries is measured by this
   method.

2. Measuring with this method will not cause much damage to the battery itself.
