5V 20mA Coin Cell Battery Tester Battery Testing Equipment

Product Overview

This system is an eight-channel coin cell battery testing instrument engineered for controlled electrochemical evaluation of small-format cells. Each channel combines independently controlled constant-current and constant-voltage sources with a dual closed-loop architecture, allowing parallel tests without sacrificing channel-level control. Its 16-bit AD and DA resolution, four-wire sensing, high input impedance, and low leakage current support dependable measurement of the low currents commonly encountered in laboratory coin-cell work.

The equipment is suited to electrode-material research, battery performance testing, small-batch cell formation, capacity grading, and battery-pack testing. It supports lithium-ion coin cells, Ni-MH cells, Zn-Mn watch batteries, and other compatible small batteries. Programmable charge, discharge, pulse, DCIR, and cycle routines make the unit practical for research laboratories, pilot-scale development groups, university facilities, and materials-science teams that need repeatable test protocols across multiple cells.

Built for continuous laboratory operation, this unit combines controlled electrical performance with defined safety limits, power-loss data protection, offline testing capability, centralized MySQL data management, and TCP/IP communication. Stable full-scale accuracy specifications, a fast current response, configurable end conditions, and 10 Hz recording provide a robust basis for generating traceable test data under demanding development and qualification workflows.

Key Features

• Eight Independently Controlled Channels: Each channel has an independent constant-current and constant-voltage source, enabling separate protocols and operating conditions across eight concurrent coin-cell tests. This configuration increases throughput while preserving channel-specific control.

• Dual Closed-Loop Source Architecture: The constant-current and constant-voltage sources use a dual closed-loop structure. This design supports controlled output behavior and stable regulation during charge, discharge, formation, and cycling work.

• Broad Low-Current Measurement Coverage: Three per-channel output ranges cover 5uA to 20mA, supporting sensitive material studies as well as higher-current small-cell testing. The current ranges allow laboratories to select a suitable operating window for varied coin-cell chemistries and capacities.

• Precision Voltage and Current Performance: Voltage and current accuracy are specified at ± 0.05% of FS, with ± 0.05% of FS stability. The unit also provides a controlled constant-voltage range from 25mV to 5V and a minimum discharge voltage of -5V.

• Four-Wire Voltage and Current Sampling: Four-wire connection technology helps the equipment obtain voltage and current detection samples with a dedicated sensing arrangement. This is especially relevant where stable low-current test results and controlled cell evaluation are required.

• Flexible Charge and Discharge Programming: The system supports constant-current, constant-voltage, constant-current constant-voltage, constant-power, constant-resistance, and pulse-related operating modes as specified. Users can apply cutoff conditions based on voltage, current, time, capacity, energy, and, for charging, -△V.

• Advanced Pulse and DCIR Capability: Charge and discharge pulse routines can use constant-current or constant-power modes, with a minimum pulse width of 500ms and up to 32 different pulses in one pulse step. Custom data-point selection for DCIR calculation supports structured internal-resistance evaluation.

• Long-Duration Cycling Control: Cycle testing spans 1 to 65535 cycles, with up to 254 work steps in a single cycle and up to three levels of nested cycles. This gives research teams a controlled framework for extended cycling and multi-stage test plans.

• High-Resolution Data Capture: Data can be recorded at 10Hz with a minimum time interval of 100ms, minimum voltage interval of 10mV, and current-change intervals matched to each range. These settings support data collection for transient behavior, cycling trends, and protocol verification.

• Networked Data Management and Protection: MySQL centralized database management, TCP/IP communication, Ethernet connectivity, Excel 2003/2010 and TXT export, offline testing, and power-loss data protection support organized laboratory data handling. Configurable safety limits further help protect test work from defined voltage, current, capacity, and delay thresholds.
