AT526 Battery Impedance Tester

Overview

The AT526 Battery Impedance Tester is a benchtop instrument for rapid measurement of battery internal resistance and DC voltage in laboratory, pilot-line, and production environments. It operates with a fixed 1 kHz AC test signal and measures low resistance together with open-circuit voltage, making it well suited to fast battery screening, contact resistance checks, and supercapacitor ESR testing. In practical terms, this type of instrument is designed for quick pass/fail and quality-control measurements rather than full electrochemical impedance spectroscopy across a wide frequency range.

Applications and Compatibility

This battery impedance tester is suitable for lithium-ion batteries, lead-acid batteries, alkaline batteries, button cells, UPS batteries, and supercapacitor ESR screening. It fits well into battery R&D, incoming inspection, manufacturing QA, and pack assembly workflows. It can also sit alongside complementary ScienceGears platforms such as battery cyclers, electrochemical cells, and potentiostat-based systems when deeper electrochemical analysis is required.

Why Choose ScienceGears

ScienceGears supports researchers and engineers across Australia and New Zealand with technically informed instrument selection, practical application guidance, and integration into broader electrochemistry and battery testing workflows. For teams that need fast, repeatable internal resistance and voltage checks without moving to full-spectrum impedance analysis, the AT526 is a strong and efficient choice.
