Introduction: The IEST HSD1000 High Precision Self-Discharge Tester is designed for accurate, long-term monitoring of leakage current and self-discharge kinetics in lithium-ion batteries using a high-precision potentiostatic method. Featuring a 24-bit ADC architecture, it delivers a $1\ \mu\text{V}$ resolution and a $30\text{ nA}$ detection limit, while supporting automatic multi-range switching and compatibility with coin, pouch, prismatic, and energy storage cells. The system empowers battery engineers to evaluate calendar aging, screen for physical micro-short circuits, optimize advanced material chemistries (such as LMFP, silicon-carbon, and solid-state), and ensure cell consistency for EV and ESS production lines.
