High-precision multi-range battery testing system for cylindrical cells, pouch cells, and advanced electrochemical research applications.
The Neware CT-4008T-5V6A Battery Tester is a high-precision multi-range battery testing system designed for lithium-ion battery research, electrochemical analysis, and laboratory-scale battery development. As part of the widely adopted CT-4000 series, the system combines high accuracy, rapid data acquisition, and flexible current range control for demanding battery testing applications.
Equipped with 8 independent testing channels, the system supports a voltage range from 25mV to 5V and programmable multi-range current control up to 6A. With ±0.05% FS voltage and current accuracy, it enables highly stable and repeatable testing for cylindrical cells, pouch cells, and electrochemical systems.
The CT-4008T platform supports DCIR analysis, dQ/dV analysis, pulse testing, cycle life testing, and three-electrode system testing. Due to its fast data acquisition capability and stable low-current control, it is also suitable for supercapacitor and EDLC testing applications.
The system includes a main testing unit and a middle machine communication controller. One middle machine can manage up to 10 main testing units, enabling scalable laboratory expansion and centralised software control.

What types of batteries can this system test?
It is designed for cylindrical cells, pouch cells, and other rechargeable battery systems within a 5V range.
What is a middle machine?
The middle machine acts as the communication interface between the PC and battery cyclers.
How many cyclers can one middle machine control?
One middle machine can control up to 10 testing units.
Does the system support electrochemical analysis functions?
Yes, it supports DCIR analysis, dQ/dV analysis, pulse testing, and three-electrode testing.
Can existing middle machines be reused?
Compatibility depends on the version of the existing middle machine. Older versions may not support newer cyclers.
