The causes can be:
All of this can soon have a negative effect on the health of a battery.
Various common failure modes such as sulphation, the short circuit element, the dryness of the elements, are a consequence of the careless use and which can quickly degrade the health of the battery.
Knowing the true health of the battery is not at all easy, very careful and adaptive stimulation and reading algorithms are needed in order to correctly stimulate the battery and consequently receive from it all the data necessary to make a diagnosis.
Consequently, the performance test will detect the batteries in which the state of health has decreased to the point of exhaustion of life. But what tools are needed?
