Voice Recorder Battery Testing Solutions

The 4/8 series mA battery testing system is designed for small battery testing. It supports high-precision charge/discharge cycling (current/voltage accuracy ±0.01%F.S.) and fast - charging simulation. It can accurately evaluate battery capacity fading and cycle life, ensuring voice recorder endurance and safety. 

Multi-mode charge/discharge control : it supports switching between constant current (CC), constant voltage (CV), and constant power (CP) modes. Charge/discharge current accuracy reaches ±0.01%F.S. (0.2μA - 100mA), precisely simulating voice recorder daily use like continuous recording and standby.

Cycle life laboratory: supports over 65500 cycle tests, automatically records capacity attenuation rate, and predicts battery capacity retention after three years of use, such as over 80%.

Data management: data can be exported via USB/RS232 interfaces, with cloud storage and multi - terminal access supported, enabling cross - regional data sharing.

To meet environmental temperature control needs and address limited testing space, the all - in - one series is introduced. It integrates assembly and wiring, saving testing space and simplifying procedures. 

All-in-one design: it combines charge/discharge testing and temperature control. This simplifies lab testing, reduces equipment wiring complexity, and offers a more streamlined and efficient lab testing environment.

Low-temperature performance verification: it can reach - 70℃ to simulate extreme outdoor conditions, quantifies low - temperature battery capacity attenuation (e.g., capacity retention at -10℃ >85%), and optimizes electrolyte formulations.
