Although batteries' internal resistance would ideally be zero, internal resistance exists due to a variety of factors. Internal resistance increases as a battery degrades. On battery. Internal resistance testing is carried out at each process after battery cells are filled with electrolyte and their assembly completed (charge/discharge testing, aging testing, shipping inspections, etc.). There are two methods for measuring internal resistance: the AC method (AC-IR) and the DC method (DC-IR). Testing on production lines uses the AC method, which is introduced.
[PDF Version]Battery internal resistance is a critical performance parameter that determines the runtime, power delivery, current capabilities, efficiency and health of a battery. Measuring the internal resistance allows you to analyze battery characteristics and performance for design optimization, production testing or periodic maintenance.
However, the internal resistance tests cannot tell us everything regarding battery capability or condition. Low capacity cells can be identified, but absolute predictions regarding the cell capacity are more difficult to make. Some points to consider are:

There are two methods for measuring internal resistance: the AC method (AC-IR) and the DC method (DC-IR).
The pulse load test is another method for measuring battery internal resistance. It involves applying a short-duration, high-current pulse to the battery and measuring the voltage response. The internal resistance can be calculated from the voltage drop during the pulse. 1.
Hioki's battery testers are working at battery manufacturers around the world. The following models are used in internal resistance testing in battery cell production processes. *1: Available to convert the 4-terminal pair measurement of BT4560 to 4-terminal measurement with the conversion plug. *3: Special specification of 0.01 Hz to 10 kHz.
For the team members that are involved in battery testing, the capacity testing procedure is very highly recommended. It is the only test that can accurately measure the true capacity capabilities, and provide an accurate insight into the battery operational status. Find out which method is better, battery capcity test or internal resistance test.
