1 General Safety Precautions
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.
Safety Guidelines
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.
2 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.
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.
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.
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 lowvoltage 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.

Safety Guidelines
3 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.
4 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.
GRX-3003P EST AMP
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.

Safety Guidelines
5 Charger Location
5.1 Locate the charger as far away from the battery as the
charger cables permit.
5.2 Never place the charger directly above the battery being
charged; gases from the battery will corrode and damage
the charger.
5.3 Never allow battery acid to drip on the charger when taking gravity readings or lling a battery.
5.4 Operate the charger only in a well-ventilated area that is
free of dangerous vapors.
5.5 Store the charger in safe, dry location and maintain it in
perfect condition.
5.6 Do not set the battery on top of the charger or where its
acid might drip onto the charger.
6 DC Connection Precautions
6.1
All switches should be set in the OFF position and AC cord
should be DISCONNECTED from electrical outlet before you
connect and disconnect the charger clamps. Never allow the
clamps to touch each other.
6.2 When attaching the charger clamps, be certain to make
the best possible mechanical as well as electrical connection. This will tend to prevent the clamps from slipping o
the connections, avoid dangerous sparking, and assure
safer and more ecient charging. The clamps should be
kept clean.
Hazardous voltage.
Can cause death or serious
personal injury.
Setting the switches to “OFF” does not always
disconnect the charger electrical circuit from
the AC power cord or the DC charger clamps.
7.3 Stay clear of fan blades, belts, pulleys, and any other parts
that can cause physical injury.
7.4 Turn OFF all vehicle loads, including door lights, and cor-
rect any defects in the vehicle’s electrical system that may
have caused low battery.
7.5 Check the polarity of the battery posts. The POSITIVE
(POS., P, +) post usually has a larger diameter than the
NEGATIVE (NEG., N,–) post.
7.6 Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded (as in most
vehicles), see paragraph 7.7. If the positive post is grounded,
see paragraph 7.8.
7.7 For a negative-grounded vehicle, rst connect the POSI-
TIVE (RED) clamp from the charger to the POSITIVE
(POS., P, +) ungrounded post of the battery. Then connect the NEGATIVE (BLACK) clamp to the NEGATIVE (NEG.,
N,–) post of the battery. Do not connect the clamp to the
carburetor, fuel lines, or sheet-metal body parts. When disconnecting the charger, turn all switches to OFF, discon-
nect the AC cord, remove the clamp from the NEGATIVE
battery terminal, and then remove the clamp from the
POSITIVE battery terminal.
7.8 For positive-grounded vehicle, connect the NEGATIVE
(BLACK) clamp from the charger to the NEGATIVE (NEG.,
N, –) ungrounded post of battery. Then connect the POSI-
TIVE (RED) clamp to the POSITIVE (POS., P, +) post of the
battery. Do not connect clamp to carburetor, fuel lines, or
sheet-metal body parts.
When disconnecting the charger, turn the switches to
OFF, disconnect the AC cord, remove the clamp from the
POSITIVE battery terminal, and then remove the clamp from the NEGATIVE battery terminal.
CAUTION: WHEN POSITIVE (+) POST OF VEHICLE
BATTERY IS GROUNDED, DOUBLE CHECK POLARITY.

Preparing To Charge
Inspecting the Battery
Before starting the test, visually inspect the battery for:
•Cracked, buckled, or leaking case. If you see any of these de-
fects, replace the battery. DO NOT CHARGE THE BATTERY.
•Corroded, loose, or damaged cables and connections. Re-
pair or replace as needed.
•Corrosion on the battery terminals, dirt or acid on the case
top. Clean the case and terminals using a wire brush and a
mixture of water and baking soda.
•Low electrolyte level. If the electrolyte level is too low, add
distilled water to the level indicated by the battery manufacturer. Do not overll.
GRX-3003P EST AMP
•Corroded or loose battery terminals, tray and hold-down
xture. Tighten or replace as needed.
Connecting The Clamps
Connect the charging clamps to the battery in accordance
with all precautions and safety instructions. Do not connect
either clamp to the vehicle’s chassis.
Connect the clamps to the battery posts: negative (–) black
clamp to the negative (–) post; positive (+) red clamp to the
positive (+) post.
If the clamps are not making good contact with the battery
posts, the screen displays CHECK CLAMP CONNECTIONS. Make
sure that both jaws of each charging clamp come in good
contact with the battery posts. If you accidentally reverse the
clamp connections, the charger sounds an alarm and displays
REVERSE CLAMPS.

The Diagnostic Charge will now begin. The Diagnostic
Charging mode has several individual charge cycles such as;
Hard To Charge, Bulk Charge, Top-O 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 State-of-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 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.
Aborting A Charge Session
If you need to abort the charging session, press STOP 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.
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.

will indicate how much more charge time is needed.
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

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.
