8 Channel Battery Analyzer (0.02 -10 mA, up to 5V) w/ Laptop & Software - BST8-MA

In stock
Item Number: BST8MA

BST8-MA is an eight-channel battery analyzer to analyze small coin cells and pouch from 0.02 mA to 10 mA, up to 5V. Each channel of the analyzer has an independent constant-current and constant-voltage source, which can be programmed and controlled by computer software. This system provides most applications in battery testing fields such as electrode materials research, battery performance test, small-scale battery formation, capability grading, battery pack testing, etc. Brand new laptop with MS Windows 10, and the latest version of controller software is installed and the analyzer is calibrated for immediate use.

Product Dimensions

445mm(L) x 380mm(D) x 135mm(H)


  • 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 (ExtremeTest) 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-recover

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 Windows 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.


  • CE Certified
  • NRTL certification is available upon request at an extra cost


Two-year limited warranty with lifetime support for the battery analyzer. (Note: MTI does not carry a warranty for the Laptops. In case service is needed for the laptops, please contact the laptop manufacturer directly for warranty/no warranty service.)

Application Notes 
  • New buyers must buy the software installed laptop to avoid trouble from installation. If you like to run multiple battery analyzers on one Laptop, you can just 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 changed the software for better operation
