Chapter 7: Battery Storage
The GRX continues to test the battery throughout the
charge cycle and may determine at some point that the
battery needs to be replaced even though the remaining
time to charge is not up yet.
NOTE: The actual time needed to charge the battery may
be less than the estimated time depending on the battery’s
charge acceptance and condition during the charge.
Before and during the charge cycle the battery is tested with
both Conductance and a Load bounce.
Hard to Charge Mode (HTC Mode)
The GRX uses the first portion of the total charge cycle
to closely monitor the acceptance of charge current and
energy going in to the battery.
During this mode the charger continuously analyzes the
battery to make a decision as quickly as possible.
Bulk Charge Mode / Fill Mode
Following this HTC Mode process the GRX will continue
charging in the Bulk Mode. During this charge cycle the
clock will indicate how much more charge time is needed.
Extended Charge Mode
In some cases the battery’s acceptance of charge current is
still high even when the charge time has elapsed. In this case
the charger will aut omatically start the Extended Charge
cycle and will continue charging until the charge current
drops below 7 Amps. This Extended mode makes sure that
the battery is sufficiently charged before going in the Top
Off Mode.
Top-Off Mode
When the battery is sufficiently charged to be returned to
the vehicle it will indicate this with an audible signal as well
as text on the display. If the STOP key is not pressed the
charger will continue to charge to fill the battery even more.
This mode occurs automatically at the end of the charge
cycle to allow the charger to fill 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.
Aborting a Charge Session
If you need to abort the charging session, press the STOP
key until the charge session is aborted. After aborting, the
charge data is displayed. Press EXIT to return to the MAIN
Menu.
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.
IMPORTANT: When you start a new test, the last bat-
tery test in memory will be overwritten. Remember
to record or print the results if you need to retain
them.

State-of-Health (SOH)
A factor that affects a battery’s ability to crank an engine is its
actual condition or State-of-Health (SOH). It is a measure of
the battery’s condition relative to a fresh battery.
A State-of-Health problem is most often the result of normal
wear-out mechanisms, which are dependant on vehicle
needs, climate, and operating conditions. This results in
irreversible physical and chemical changes until eventually
the battery can no longer hold a charge and supply the
power necessary to start the car and provide auxiliary power
to the electrical system.
As the battery approaches end of life, its deterioration
accelerates, until it finally fails to start the vehicle. Before
failing, the battery may start the vehicle under normal
conditions but may not be able to operate in more extreme
conditions. Extreme heat or cold could expose a weak
battery and cause it to fail.

REPLACE
BATTERY
A REPLACE BATTERY result may also
mean a poor connection between the
battery cables and the battery. After
disconnecting the battery cables, retest
the battery using the out-of-vehicle test
before replacing it.
BAD CELL–
REPLACE
Replace the battery. This decision
indicates a bad cell within the battery.
FROZEN
BATTERY
The GRX may display FROZEN
BATTERY. Warm the battery and retest.
Never charge a frozen battery. Gases
may form, cracking the case, and
leak battery acid.
