It refers to the resistance experienced by the current flowing through the interior of the battery during operation. It consists of two parts: ohmic internal resistance and polarization internal resistance. A large internal resistance of the battery can lead to a decrease in the working voltage of the battery discharge and a shortened discharge time. The size of internal resistance is mainly influenced by factors such as battery material, manufacturing process, and battery structure. It is an important parameter for measuring battery performance. Note: The standard is generally based on the internal resistance in charge state. The internal resistance of the battery needs to be measured using a dedicated internal resistance meter, rather than using a multimeter's ohm range for measurement.
