Independent Battery

Testing Laboratory


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


In the 0-18 volt range, Discharges up to 2000 amperes can be performed at temperatures from -40°C to 80°C.     


Test Temperatures from -40°C to 80°C are obtained using waterbaths, ovens, or environmental chambers with calibrated controls.     


Capacity discharge testing and recharging with a range of 0-75 volts and 0-500 amperes is also available.      

Examples of this type of
testing are: 


  •  SAE J537,  Reserve Capacity and Cold Cranking 

  • JIS D5301 5 hour, 20 hour Capacity, and High Rate Discharge Characteristics

  • JIS D5302 10 hour Capacity,
    and High Rate Discharge Characteristics


  • EN50342 20 hour Capacity Test
    and Cranking Performance Tests

Also included are various Charge Acceptance tests, Discharge Characterization Tests, and 1/2 CCA State of Health Tests.  

An Independent Battery Testing Laboratory, JBI Corporation specializes in the electrical and physical testing of lead acid batteries and cells. We have been in business for over 35 years.
