5V 50mA Coin Cell Battery Testing Equipment Battery Tester

Product Overview

This eight-channel battery testing system is designed for precise evaluation of coin cells and other low-current electrochemical devices. With a controlled voltage range from 25 mV to 5 V and three current ranges spanning 5 μA to 50 mA, the equipment supports sensitive laboratory measurements as well as repeatable charge and discharge protocols. Its four-wire sensing architecture, 16-bit AD and DA resolution, and dual closed-loop current and voltage control help maintain accurate test conditions across demanding research programs.

The unit is suited to coin cell screening, battery material development, electrode evaluation, cycle-life studies, pulse testing, and DCIR analysis. It serves battery R&D laboratories, universities, advanced materials researchers, energy storage developers, powder and coating specialists, and quality teams requiring controlled low-power testing. Independent channel control allows multiple samples or test methods to run simultaneously.

Designed for reliable long-duration operation, the equipment provides power-failure data protection, offline testing, configurable safety limits, and centralized database management. A current response time below 500 μs supports responsive test transitions, while structured data recording and TCP/IP communication simplify traceability across laboratory workflows. The system is engineered for consistent operation in controlled indoor environments from 0°C to 40°C.

Key Features

• Eight Independent Test Channels: Eight channels support parallel battery evaluation with independent control, allowing researchers to compare samples, formulations, or operating conditions without requiring separate instruments.

• Wide Low-Current Measurement Capability: Three selectable current ranges cover 5 μA to 1 mA, 1 mA to 25 mA, and 25 mA to 50 mA. This arrangement provides practical flexibility for coin cell characterization from low-current formation studies through higher-current cycling within the equipment’s output range.

• Precision Voltage and Current Regulation: Voltage and current accuracy and stability are specified at ±0.05% of full scale. The controlled voltage range from 25 mV to 5 V supports detailed testing of low-voltage electrochemical responses and common coin cell operating windows.

• Four-Wire Measurement Connection: Four-wire voltage and current sampling reduces the influence of lead resistance and connection losses. This configuration improves measurement consistency, particularly when testing low-current devices or comparing closely matched samples.

• Comprehensive Charge and Discharge Modes: Constant-current, constant-voltage, constant-current constant-voltage, and constant-power charging are available. Discharge modes include constant current, constant voltage, constant-current constant-voltage, constant power, and constant resistance.

• Advanced Pulse Testing: Pulse steps support constant-current or constant-power charging and discharging, with a minimum pulse width of 500 ms. One pulse step can contain up to 32 different pulses and can transition continuously from charging to discharging.

• Flexible Cycling and DCIR Analysis: Cycle tests support 1 to 65,535 repetitions, with up to 254 steps per single cycle and three levels of nested loop control. Users can define measurement points for DCIR calculation to support resistance tracking during cell development.

• High-Resolution Data Recording: Recording conditions can be defined by minimum time, voltage, and current intervals. Data recording reaches 10 Hz, with a minimum time interval of 100 ms and a minimum voltage interval of 10 mV.

• Integrated Protection and Data Security: Configurable upper and lower voltage limits, upper and lower current limits, capacity limits, and delay times help protect test articles and equipment. Power-failure data protection and offline testing support continuity in extended experiments.
