Chapter 6: Diagnostic Charging
Diagnostic Mode
Once the GR8 determines that the battery is good, needs
charging, and is safe to charge, it proceeds to Diagnostic Charge
Mode. During the charging session, the GR8 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 GR8 continues to test the
battery throughout Diagnostic Mode and may determine at
some point that the battery needs to be replaced.
NOTE: The actual time needed to charge the bat-
tery may be less than the estimated time depend-
ing on the battery’s charge acceptance.
When the battery requires testing, the display alternates
between the CHARGING and TESTING screens. The TESTING
screens represent a two-step process.
Step 1: The GR8 applies an electrical load and tests the bat-
tery’s response.
Step 2: The GR8 measures the battery’s CCA.
The Estimated time only appears when the charger is in
DIAGNOSTIC mode and after the ve -minute printout.
Top-Off Mode
Following the Diagnostic Charge Mode process the GR8 will
prompt you to stop the process or continue on in Top-O
Mode. After two minutes the GR8 will automatically enter Top-
O mode if there is no user input
This mode occurs automatically at the end of the charge cycle
to allow the charger to ll a good battery to capacity. Top-
O Mode ends when the battery’s acceptance of the charge
current goes below 2 amps, or when you press the STOP
button.
Aborting a Charge Session
If you need to abort the charging session, press and hold the
STOP key until the charging session is aborted. After aborting,
select NEXT to return to the Main Menu.
