Battery analyzer
Battery analyzers are mainly based onElectrochemical principlesBy using methods such as cyclic charge/discharge, AC impedance spectrum (EIS), or constant-current intermittent titration (GITT), the voltage, current, temperature, and internal impedance parameters of the battery can be measured. This instrument can analyze the charge state (SOC), health status (SOH), capacity decay, internal resistance, and gas generation conditions in real time, and is commonly used in battery design, quality control, and life assessment.
10mA
The eight-channel battery analyzer can analyze small button and soft-pack batteries with current ranges from 0.02 mA to 10 mA and voltage up to 5 V. Each channel of the analyzer is equipped with an independent constant current source and constant voltage source, which can be programmed and controlled through computer software. This system can be widely applied in battery testing fields, such as electrode material research, battery performance testing, small-scale battery formation, performance grading, battery assembly testing, etc. The new notebook has been installed with the Windows 10 operating system and the latest version of controller software, and the analyzer has been calibrated and is ready for immediate use.

| Channels | Eight independent programmable channels Each channel can set different working modes and functions independently |
| Battery Holders | One type of battery holder is included in the BST8-MA standard package: 8-Channel clips sets for coin cell. (Pic. 1) Optional battery holder: 8-Channel alligator clips sets for cylindrical cells. (Pic. 2) 8-Channel clip sets with bayonet connectors for pouch cell. (Pic. 3) |
| Programs & Software | The software (Extreme Test) is included to set various working modes for measuring capacity and life cycle for all types of rechargeable batteries Working modes Include constant current discharge, constant current charge, constant voltage charge, constant resistance discharge, rest, etc Limited threshold conditions include voltage, current, time, capacity, negative voltage slope, etc With real-time monitoring windows and integrated graph/data windows, the testing process can be observed more directly and efficiently During the test, the software will provide instructions and warnings for assistance The calibration software can be used to calibrate the analyzer |
| Test reports and curves for analysis | Different types of curves can be created by software based on user definition. (Voltage-time curve, current-time curve, capacity-voltage curve, loops times charge/discharge capacity curve, loops times charge/ discharge efficiency curve, etc) Data reports are created by the software. Users can easily compare the performance of the batteries tested in channels both visually and statistically |
| Protection and Auto-recovery | If power failures occur during testing, the system will shut down all operating channels. Once power is recovered, the system will automatically reconnect with the PC, and the program can be resumed/continued manually. |
| Laptop Computer | Brand new laptop ( 4GB RAM 128GB SSD) with MS Window 10, and the latest version testing software is installed and calibrated for immediate use. Notice: It is suggested to use an external hard drive to keep an instant backup of the collected data. |
| Compliance | CE Certified NRTL certification is available upon request at an additional cost. |
| Application Notes | New buyers must buy the installed software on a laptop to avoid trouble during installation. If you want to run multiple battery analyzers on one laptop, you can simply buy multiple analyzers with one laptop, which are offered at a discounted price. Warning: Please choose NEVER for Screen and Sleep in the Power& Sleep setting of your computer, or it may lose connection from the battery analyzer. Multiple battery analyzers can be connected to 1 PC via an ethernet switch ($100.00). Since August 1, 2021, MTI has changed the software for better operation. |
