Charging Modes

Diagnostic Charging has four modes (Initial Analysis, Deep Scan 

Test, Diagnostic Mode, Top-Off Mode) that the GR8 may use to 

determine the State-of-Health of the battery while bringing it 

to a full State-of-Charge.

Initial Analysis

The  GR8  first  analyzes  the  battery  and  may  make  a  decision: 

GOOD BATTERY, REPLACE BATTERY, or REPLACE-BAD CELL. For 

diagnostic  charge  analysis,  progress  is  shown  by  the  left  to 

right movement of a progress bar.

Deep Scan Test

In some cases the GR8 may need to further analyze the battery 

to determine whether the battery should be replaced or it has 

a  significant  chance  to  be  recovered.  It  will  then  conduct  a 

Deep Scan Test of the battery for a few seconds.

 

After the Deep Scan Test the GR8 will either display the results 

or  give  you  the  option  to  perform  the  5-Minute  Discharged 

Battery Test. Although this test takes several minutes, it gives 

a  more  precise  result  for  difficult-to-diagnose  batteries.  The 

decision tree of the test is shown below.
