Infiniti vehicles equipped with standard lead/acid batteries use one of two different types with unique battery rating specifications: JIS & CCA.
JIS = Japan Industrial Standard, used for Japan produced batteries
CCA = Cold Cranking Amps, standard for North American produced batteries
IMPORTANT:
^ JIS batteries have different testing specifications than CCA batteries.
^ If you must use the GR-8 Battery Tester in a mode other than MODEL mode, JIS Mode MUST ALWAYS BE USED for JIS batteries otherwise
an incorrect result will occur. NEVER test a JIS battery using the CCA test in the GR-8; the test software in the GR-8 is different for JIS and CCA
modes. ANY CCA value you may have for a JIS-type battery is inaccurate for testing purposes.
ALWAYS test with the GR-8 using the MODEL mode (if available).
^ Selecting MODEL and vehicle type will automatically select the proper JIS or CCA value for the Original Equipment battery.
