Ultra-low current battery testing system for micro-current analysis, coin cell research, and high-precision electrochemical testing.
The Neware CT-4008T-5V10mA-164 Battery Tester is a high-precision micro-current battery testing system designed for advanced electrochemical research and ultra-low current applications. With eight independent channels and high-resolution measurement capability, the system is ideal for coin cell testing, material characterisation, and low-current battery analysis.
The system supports a voltage range from 25 mV to 5V and multiple current ranges down to 5 μA, enabling highly sensitive detection and control of electrochemical behaviour. With ±0.05% FS accuracy for both voltage and current, it ensures precise and stable testing performance for long-term experiments and micro-current measurements.
Advanced testing capabilities include constant current, constant voltage, constant power, pulse testing, and DC internal resistance (DCIR) analysis. The system also supports nested cycle programming and multi-step test profiles, making it suitable for complex electrochemical workflows.
With Ethernet-based communication and MySQL database architecture, the system enables real-time monitoring, automated control, and efficient data export. Its compact 1U rack-mounted design makes it ideal for high-density laboratory setups.
