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 by this article. . The internal resistance provides valuable information about a battery as high reading hints at end-of-life. This is especially true with nickel-based systems. Resistance measurement is not the only performance indicator as the value between batches of lead acid batteries can vary by 5–10 percent. . 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. We will delve into the principles of internal resistance, the tools required, step-by-step instructions. . With several measurement methods available—each having distinct advantages, limitations, and applications—it's essential to adopt the right approach for accurate results. This article will explore the fundamental principles of battery internal resistance and compare widely-used measurement. . A commonly encountered school-level Physics practical is the determination of the internal resistance of a battery – typically an AA or D cell. Typically this is based around a simple model of such a cell as a source emf in series with a small resistor. One technique is electrochemical impedance spectroscopy (EIS). During this test an AC signal is applied to the battery over a wide spectrum of frequencies and the. .
