Chapter 2: Diagnostic GR8
The Diagnostic charging function has four modes to
determine the State-of-Health of the battery while
bringing it to a full State-of-Charge.
Initial
Analysis:
The charger rst analyzes the battery and
makes a decision: REPLACE BATTERY (or
REPLACE-BAD CELL) or GOOD BATTERY.
A warranty code is generated when testing by
CCA or JIS.
 Diagnostic
Mode:
Once the charger determines that the battery
is good, needs charging, and is safe to
charge, it proceeds to Diagnostic Charge
Mode. During the charging session, the
charger provides updates of the charging
voltage, charging current, remaining time
to charge, charging mode, and the amount
of charge replenished into the battery in
amp-hours. The charger continues to test
the battery throughout Diagnostic Mode and
may determine at some point that the battery
needs to be replaced.
Top-Off
Mode:
This mode occurs automatically at the end of
the charge cycle to allow the charger to ll a
good battery to capacity. Top-Off Mode ends
when the battery’s acceptance of the charge
current goes below 2 amps, or when you
press the STOP button.
Recovery
Mode:
In some cases, the charger automatically
switches to Recovery Mode in an attempt to
recover a hard-to-charge battery.
Make sure all vehicle accessory loads are o, the key is not in
the ignition, and the doors are closed.
When using the ARROW keys to select option buttons, press
NEXT to continue to the next step. When using the keypad,
no additional keypress is needed. Use BACK to return to the
Main Menu at the start of the test and or the previous screen
during the test.
IMPORTANT: When starting a new charge session,
the last battery test results in memory will be over-
written. Remember to record or print the results retain
them.
1. At the Main Menu select the DIAGNOSTIC icon.
2. Select the battery location.
1 OUT OF VEHICLE
2 IN VEHICLE
A battery not connected to a vehicle is considered OUT OF
VEHICLE.
3. Select the battery rating.
1  CCA
2  JIS
4. Select the BATTERY TYPE.
1  FLOODED
2  AGM/SPIRAL
3  AGM/FLAT PLATE
5. Enter the BATTERY RATING. Scroll to the rating and press
SELECT to begin the test.
580 CCA
Entry range is between 100 to 3000, except for DIN and
IEC, which have a range of 100 to 1000. Hold  or  to
increase your scrolling speed.
CCA Cold Cranking Amps. The most common rating for
starting batteries rated at 0 ºF.
JIS Japanese Industrial Standard. Shown on a battery
as a combination of numbers and letters, for
example: 26A17
IMPORTANT: It is important to input the correct
test parameters. If you use the wrong param-
eters, an inaccurate test result will occur.
For JIS, scroll to the correct JIS number.
26A17
26A19
26B17

Initial Analysis
The progress of the analysis is shown by the left to right
movement of a progress bar.
If additional testing is required, progress is shown by the
clockwise ll of a pie chart.
