Tips: How does a digital battery tester work?
As the battery is used, it will gradually age. The main reason for aging is that the surface of the battery is vulcanized and corroded, and the active material falls off, which can no longer carry out effective chemical reactions. This is the main reason that most batteries cannot continue to be used.
The working principle of digital battery tester is to determine the chemical reaction ability by measuring the conductivity of the surface of the electrode plate, and to infer the change of the battery capacity through the change of the electrode plate, thereby determining the health of the battery. For car/SUV batteries, cold-start current is the most important indicator, and it is displayed in units of cold-start current in order to make it more intuitive for car owners. When the customer uses the battery, input its rated CCA value according to the label of the automotive battery, and then the battery tester will measure a conductance CCA value. The 12V battery tester compares the difference between the two CCA values to determine the health condition of the battery.
