The OPT-5V-1mA Battery Testing Equipment is engineered to meet the demands of ultra-low current battery analysis with exceptional precision and stability. Designed with independent channels, each unit operates with a dedicated constant current and constant voltage source supported by a closed-loop control system. This ensures highly accurate and interference-free measurements, even at microampere levels.

The device supports a voltage range from 10 mV to 5 V and an extremely fine current range from 0.002 mA to 1 mA, making it ideal for testing advanced energy storage devices such as micro-batteries, solid-state batteries, and research-grade electrochemical cells. With an accuracy of ±0.1% FS and stable output performance, it guarantees consistent and reliable results across long-duration experiments.

Flexible testing capabilities include constant current, constant voltage, and combined charge modes, along with constant current discharge. Users can define multiple end conditions such as voltage, current, time, or capacity, allowing highly customizable test protocols. The system also supports advanced cycling functions with up to 65,535 loops and multi-layer nested loop programming, enabling complex and automated testing sequences.

Data acquisition is handled with high resolution and can be recorded based on configurable time, voltage, or current intervals. Results can be exported in various formats, including Excel, TXT, and graphical outputs. The integration of a MySQL database and TCP/IP communication via Ethernet allows seamless data management and remote operation.

Safety is ensured through both software and hardware protections, including programmable limits, delay protection, power-loss data retention, and anti-reverse connection mechanisms. Combined with a compact 8-channel design and user-friendly interface, the OPT-5V-1mA is an excellent choice for precise, low-current battery testing applications.
