Explanation

Under a certain charging and discharging system, the cycle charging and discharging times that the battery can withstand before the cell capacity drops to a specified value are called secondary cell. The influencing factors include electrode materials, electrolyte, separator, manufacturing process, depth of discharge, etc. In the testing of battery life, the capacity of the battery is not the only indicator to measure the battery, but should also comprehensively consider its voltage characteristics, changes in internal resistance, etc.
