Testing Laboratory


JBI can perform Life Cycle Testing using constant current, constant power, constant resistance, and/or constant voltage.  JBI has over 350 programmable charge / discharge testing circuits.      

In the 0-18 volt range, Life Cycle Testing up to 300 amperes charge and discharge can be performed on calibrated programmable circuits at temperatures from -40°C to 80°C.   

Test Temperatures from -40°C to 25°C are obtained using cold boxes and environmental chambers with calibrated controls.       

Test Temperatures from 25°C to 80°C are obtained using waterbaths, ovens, or environmental chambers with calibrated controls.       
Life Cycle Testing with a range of 0-75 volts and 0-500 amperes is available. A range of 0-2000 amperes, 0-18 volts discharge, with 0-100 amperes, 0-18 volt charge is also available.

Examples of this type
of testing are: 


  • SAE J240, J2801, & J2185  

  • BCIS-06 (Golf Cart Cycling and Repeat Reserve Capacity Cycling)  

  • JIS D5301 Light and Heavy Endurance   

  • JIS D5302 Deep Cycle Endurance
    and Shallow Cycle Endurance


  • EN50342 Endurance and Corrosion tests, Requirements 1, 2, 3, & 4 and Life Cycle Tests in many other published specifications

Also included are various Water Loss tests, Depth of Discharge tests, 
GM CERT Testing, and
Overcharge Testing
