Completing a Charge Session
The charge session is complete when the proper amount of
charge is put back into the battery or the remaining estimated
time to charge counts down to zero.
If the GR8 nds that the battery is bad before the end of the
estimated time to charge, it displays the decision REPLACE
BATTERY or BAD CELL-REPLACE and the results.
If charging at the side posts or jump start posts and the test
data is inconclusive, the GR8 displays the decision JUMP
START POST or SIDE POST TEST. A JUMP START POST decision
prompts you to test at the battery. A SIDE POST TEST decision
prompts you to test using the side post adapters.
When the decision is GOOD BATTERY, the GR8 gives you
the option of topping o the battery’s charge level before it
displays the results.
