1. What is battery internal resistance?

    It refers to the resistance that a battery experiences when current flows through its interior during operation. It is composed of two parts: ohmic resistance and chemical resistance. The high internal resistance of the battery can cause a drop in the discharge voltage and shorten the discharge time. The size of internal resistance is significantly influenced by factors such as battery data, manufacturing process, and battery structure. It is an important parameter for measuring battery performance. Note: Some cases are based on the charging state internal resistance as the standard. The internal resistance of a battery needs to be measured with an internal resistance meter, not with a multimeter in the ohm range.

2. What is the nominal voltage?

    The nominal voltage of a battery refers to the voltage expressed during abnormal operation, with a nominal voltage of 1.2V for secondary nickel cadmium nickel hydrogen batteries and 3.6V for secondary lithium iron phosphate batteries.

3. What is open circuit voltage?

    Open circuit voltage refers to the potential difference between the positive and negative terminals of a battery when there is no current flow in the circuit during non working conditions. Working voltage, also known as terminal voltage, refers to the potential difference between the positive and negative terminals of a battery when there is an expired current in the circuit during operation.
