Product Details


■ Product Overview

This instrument employs the most advanced AC discharge testing method. , Capable of accurately measuring the terminal voltage and internal resistance of a storage battery. , This allows for assessing the quality and technical condition of the battery’s capacity. Customers can select a battery internal resistance test based on their specific circumstances. , Voltage testing and capacity estimation serve as the basis for internal resistance matching when assembling new battery packs. ; Measuring the battery’s internal resistance before and after discharge to identify truly degraded cells. ; Two operation modes: key input and LCD touch. ; It can perform grouped measurements on battery packs. , Single-section measurements can also be performed.
