(100mA and below)
The CT3002A/C battery test systems are upgraded from CT2001A/C with higher precision and data logging rates. The tester can be used to run precision tests for coin cells, pouch cells, prismatic cells, and especially supercapacitors (ultra-capacitors). Each tester has 8 independent channels, which can be programmed to run constant current charge/discharge, constant voltage charge, constant power discharge, constant resistant discharge, and direct current internal resistance (DCIR) tests.
The CT3002 models share the same software as the CT2001 models, while mixed models could not be connected in series to the same computer. All tester units run the same software.
The following is a comparison of the specifications.
