Safety Guidelines
General Safety Precautions
1. IMPORTANT SAFETY INSTRUCTIONS. IT IS OF UTMOST
IMPORTANCE THAT BEFORE USING YOUR CHARGER,
YOU READ THIS MANUAL AND FOLLOW THE SAFETY AND OPERATING INSTRUCTIONS EXACTLY. SAVE
THESE INSTRUCTIONS.
Risk of explosive gases
Batteries generate explosive gases during normal
operation, and when discharged or charged.
1.1 To reduce risk of battery explosion, follow these safety
instructions and those published by the battery manufacturer and the manufacturer of any equipment you
intend to use in the vicinity of a battery. Review cautionary marking on these products and on the engine, and
on the vehicle or equipment containing the battery.
Charging a non-rechargeable battery may
cause the battery to burst.
To reduce the risk of injury, only charge rechargeable
lead-acid type batteries including maintenance-free,
low-maintenance, or deep-cycle batteries.
If you are uncertain as to the type of battery you are
attempting to charge, or the correct procedure for
checking the battery’s state of charge, contact the seller
or battery manufacturer.
1.2 Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of re,
electric shock, or injury to persons.
1.3 To reduce risk of damage to the electric plug and cord,
pull by the plug rather than by the cord when disconnecting the charger.
1.4 Position the AC and DC leads to avoid tripping over
them and to prevent damage by hood, doors, or moving
engine parts; protect from heat, oil, and sharp edges.
1.5 Do not operate the charger if it has received a sharp
blow, been dropped or otherwise damaged in any way;
take it to a qualied service center.
1.6 Do not disassemble charger; take it to a qualied service
center when repair is required. Incorrect reassembly
may result in a risk of electric shock or re.
1.7 To reduce risk of electric shock, unplug the charger from
the AC outlet before attempting any maintenance or
cleaning. Turning o the controls will not reduce this
risk.
Remove marine “boat” batteries and charge
them on shore.
Charging marine batteries on-board requires specially designed equipment for marine use.
1.8
Connect and disconnect the battery leads only when
the AC supply cord is disconnected.
1.9
Do not overcharge the battery.
1.10
Charge the battery in a dry, well-ventilated area.
1.11
Never place articles on or around the charger, or locate
the charger in a way that will restrict the ow of cooling
air through the cabinet.
1.12
An extension cord should not be used unless absolutely
necessary. (See paragraph 4.3.)
1.13 Have a damaged cord or plug replaced immediately.
1.14
Do not expose the charger to rain or snow.
Personal Precautions
2.1 Always have someone within range of your voice, or
close enough to come to your aid, when working around
lead acid batteries.
2.2 Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
2.3 Wear complete eye protection, clothing protection, and
wear rubber soled shoes. Place damp cloth over battery
to protect against acid spray. When ground is very wet
or covered with snow, wear rubber boots. Avoid touching eyes while working near battery.
2.4 If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eye, immediately ush with cold running water for at least 10
minutes, and seek medical attention.
2.5 NEVER smoke or allow a spark or ame in vicinity of a
battery or engine.
2.6 Be extra cautious to reduce risk of dropping a metal tool
onto the battery. It might spark or short circuit the battery or other electrical part that may cause an explosion.
2.7 Before working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces,
watches, etc. A lead-acid battery can produce a short
circuit current high enough to weld such items causing
a severe burn.

Safety Guidelines
Non-rechargeable batteries may burst when
charging causing personal injury and damage.
To avoid electrical shock or burn, never alter the charger’s original AC cord and plug. Disconnect plug from
outlet when charger is idle.
The charger is not intended to supply power to a
low-voltage electrical system other than applications
using rechargeable, lead-acid type batteries. Do not
use the battery charger for charging dry-cell batteries
commonly used with home appliances. These batteries
may burst and cause personal injury and property
damage.
2.8 NEVER charge a frozen battery; thaw it out rst.
Preparing To Charge The Battery
3.1
If it is necessary to remove the battery from vehicle to
charge it, always remove the grounded terminal from the
battery rst. Make sure all accessories in the vehicle are
o, so as not to cause an arc.
3.2
Be sure the area around the battery is well ventilated
while the battery is being charged. Gas can be forcefully
blown away by using a piece of cardboard or other nonmetallic material as a fan.
3.3
Clean the battery terminals. Be careful to keep corrosion
from coming into contact with your eyes.
3.4 Add distilled water in each cell until the battery acid
reaches the level specied by the manufacturer. This
helps purge excessive gas from the cells. Do not overll.
For a battery without caps, carefully follow the manufacturer’s recharging instructions
3.5 Study all battery manufacturer’s specic precautions
such as removing or not removing cell caps while charging and recommended rates of charge.
3.6 Determine the voltage of the battery by referring to the
car owner’s manual and make sure that the output voltage selector switch is set at the correct voltage. If the
charger has an adjustable charge rate, charge the battery initially at lowest rate. If the charger has only one
voltage, verify that the battery voltage matches the voltage of charger.
For a charger not having an output voltage selector
switch, determine the voltage of the battery by referring
to car owner’s manual and make sure it matches the
output rating of the battery charger.
Grounding & Power Cord Connections
4.1 The charger must be grounded to reduce risk of
electric shock. The charger is equipped with an electric
cord having an equipment grounding conductor and
a grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Hazardous voltage.
An improper connection can result in
electric shock
To avoid electrical shock or burn, never alter
the charger’s original AC cord and plug. Disconnect plug from outlet when charger is idle.
IF THE PLUG DOES NOT FIT THE OUTLET, HAVE
A PROPER OUTLET INSTALLED BY A QUALIFIED
ELECTRICIAN.
4.2
This battery charger is for use on a nominal 220-volt circuit.
Hazardous voltage.
An improper connection can result in
electric shock
Before using an adapter be certain the center
screw of the outlet plate is grounded. The rigid
ear or lug extending from the adapter must be
connected to a properly grounded outlet. Make
certain it is grounded. If necessary, replace the
original screw that secures the adapter ear or
lug to the cover plate and make the ground
connection to the grounded outlet.
4.3 An extension cord should not be used unless absolutely
necessary. Use of an improper extension cord could result in a risk of re and electric shock. If an extension
cord must be used, make sure:
a. that the pins on plugs of the extension cord are the
same number, size, and shape as those of the plug
on the charger;
b. that the extension cord is properly wired and in
good electrical condition;
c. that the wire size is large enough for the AC
ampere rating of charger.

Chapter 5: Diagnostic Charging
Charging Modes
The Diagnostic Charging mode knows several individual
charge cycles such as; Hard To Charge, Bulk Charge, TopO Mode and Extended Charge. All these modes will be
performed automatically with one intention; determine the
State-of-Health of the battery and bringing it to a full Stateof-Charge.
Initial Analysis
The GRX rst analyzes the battery to nd out its original
state. Based on this the charger really starts charging. This
initial test is done with both Conductance and a Load cycle
and depending of the condition we also use a Deep Scan
procedure.
Step 1:
The GRX tests the battery with conductance.
Step 2: If needed!
The GRX tests the battery with a Deep Scan.
Step 3:
The GRX applies a load and monitor the battery’s response
Step 4:
The GRX performs a nal conductance test.
Once the GRX determines that the battery is healthy, needs
charging, and is safe to charge, it proceeds.
During the charging session, the GRX provides updates
of the charging voltage, charging current, remaining time
to charge and the amount of charge replenished into the
battery in amp-hours.
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 rst 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 automatically 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 suciently charged before going in the Top
O Mode.
Top-Off Mode
When the battery is suciently 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 ll the battery even more.
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 the STOP
key until the charge session is aborted. After aborting, the
charge data is displayed. Press END 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.

tery test in memory will be overwritten. Remember
to record or print the results if you need to retain
them.

screen. To print, press the PRINT soft key.
State-of-Health (SOH)
A factor that aects 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 nally 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.

Chapter 7: Power Supply
The Power Supply function should be used when ever the
vehicle comes in to the workshop for regular maintenance
or ECU re-ashing.
Re-ashing an ECU can take up to several hours and during
that period a lot of current can be drawn from the battery. To
support the battery during this process you use the power
supply function.
Always make sure that when you work on the vehicle the
charger is switched in to the Power Supply function so that
you ensure that when the work is done the battery’s state of
charge is maintained at a healthy level.
1. From the MAIN Menu, highlight the POWER SUPPLY

response.
When the battery has a low state of charge the charger
will ask you if you want to charge the battery rst prior to
starting the power supply function. It is advised to do this
because ECU programming with a battery in a low state
of charge can cause damage to the ECU when the battery
voltage drops below a certain limit.
If YES is selected the battery will be charged in the
Diagnostic Charge mode until it is ready. It will automatically
jump back to the Power Supply screen and maintains the
battery with the selected voltage threshold.
