Safety Guidlines

Safety InstructionsGR8 1100

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 re duce the risk of injury, only charge
rechargeable lead-acid type batteries including
maintenance-free, low-maintenance, or deep­cycle 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 qualied service center.

1.6 Do not disassemble charger; take it to a qualied 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. (See sections 3 and 10 in

the safety instructions)

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.

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.

properly installed and grounded in accordance with all lo­cal codes and ordinances.

Non-rechargeable batteries may
burst when charging causing
personal injury and damage.

Only c harg e rech a rgea b l e le a d -ac i d
maintenance-free, low-maintenance or deep­cycle batteries.

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.

2.9 NEVER charge a frozen battery; thaw it out rst.

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 specied by the manufacturer. This helps
purge excessive gas from the cells. Do not overll. For a
battery without caps, carefully follow the manufacturer’s
recharging instructions

3.5 Study all battery manufacturer’s specic precautions such
as removing or not removing cell caps while charging and
recommended rates of charge.

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 120-volt cir­cuit and has a grounding plug that looks like the plug il­lustrated in Figure A. A temporary adapter, which looks like
the adapter illustrated in Figures B and C, may be used to
connect this plug to a two-pole receptacle as shown in
Figure B, if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualied electrician.

USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A
GROUNDING-TYPE RECEPTACLE IS NOT AVAILABLE, DO
NOT USE THIS APPLIANCE UNTIL THE PROPER OUTLET IS
INSTALLED BY A QUALIFIED ELECTRICIAN.

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.

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.

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 And AC Power Cord Connection
Instructions

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

Midtronics Inc. 7000 Monroe Street Willowbrook, IL 60527

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

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 ecient charging. The clamps should be
kept clean.

7. Installing The Battery

Risk of explosive gases

A spark near the battery may cause a battery
explosion. Follow these steps when the battery
is installed in the vehicle to reduce the risk of
explosion.

7.1 Before working on the vehicle, rmly apply the emergen­cy brake and place the gear shift to NEUTRAL—shift an
automatic transmission to PARK.

7.2 Locate the charger as far away from the battery as the
charger cords permit and position the AC and DC cords to
avoid stepping on or tripping over them and to prevent

Help Menu and Soft Keys

In addition to the HELP soft keys, the GR8 provides a

Help Menu with a glossary of test-related denitions that

you may want to review prior to testing. The menu also
provides troubleshooting information and phone numbers
for Midtronics Customer Service, in case you encounter a
problem and/or need technical assistance.

Chapter 6: Charging Menu—Diagnostic Charging GR8 1100

Chapter 6: Charging Menu

Diagnostic Charging Modes

Diagnostic Charging has four modes that the GR8

may use to determine the State-of-Health of the
battery while bringing it to a full State-of-Charge.

Initial

Analysis:

Diagnostic

Mode:

The GR8 first analyzes the battery and
makes a decision: REPLACE BATTERY (or
REPLACE-BAD CELL) or GOOD BATTERY. A
test code appears for all decisions.

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.

1. In the Main Menu the CHARGING icon is highlighted. Press
the SELECT key.

2. In the Charging Menu use the LEFT (t) or RIGHT (u) AR-

ROW key to highlight the DIAGNOSTIC icon. Press the SE-
LECT soft key.

3. Use the UP (p) or DOWN (q) ARROW key to select the
battery LOCATION, or press the corresponding numerical
key (1 or 2) to move the dot to the option button of your
choice.

1 OUT OF VEHICLE

2 IN VEHICLE

Top-O

Mode:

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.

Recovery

Mode:

In some cases, the GR8 automatically
switches to Recovery Mode in an attempt to
recover a hard-to-charge battery.

Selecting the Charging Parameters

Make sure all vehicle accessory loads are o, the key is not in
the ignition, and the doors are closed.

IMPORTANT: When you start a new charge ses-

sion, the last battery test results in memory will
be overwritten. Remember to record or print the
results if you need to retain them.

The BACK soft key returns you to the Main Menu at
the start of the test and to the previous screen as you
progress.

NOTE:

If you use the ARROW keys to select

option buttons, press the NEXT soft key to
continue to the next step. If you use the alpha­numeric keypad to enter the number preced­ing the option button, no additional keypress is
needed.

Initial Analysis

When you select the last charge parameter the GR8 begins the
initial battery analysis. The progress of the analysis is shown by
the left to right movement of a progress bar.

If additional testing is required, progress is shown by the
clockwise ll of a pie chart.

Deep Scan Test

In some cases the GR8 may need to further analyze a deeply

NOTE: The actual time needed to charge the battery

may be less than the estimated time depending 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.

Aborting a Charge Session

If you need to abort the charging session, press the STOP key.
You will not be able to obtain a test code for an uncompleted
charge. After aborting, select NEXT 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.

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 REPLACE-BAD CELL and the results.

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.

Recovery Mode

In some cases the GR8 may give you the option of selecting
Recovery Mode before displaying the nal results. Recovery

Mode optimizes the charge for a hard-to-charge battery.
To continue the charge session, press the YES soft key in
response to:

The maximum charge time in Recovery Mode is three hours,
although most batteries will nish charging sooner. During
Recovery Mode the charger continuously analyzes the battery
to make a decision as quickly as possible.

If you select NO, the charge session aborts (stops) and you will
not be able to obtain a test code.

If you make no selection within two minutes, the GR8
automatically proceeds to Recovery Mode.

Top-Off Mode

Top-off charging fills a good battery to capacity after a
completed charge session. The GR8 gives you the option of
selecting YES to proceed to Top-O at any time or NO to
display the results.

If you make no selection within two minutes, the charger
automatically begins Top-O Mode.

You have the option of stopping Top-O Mode at any time by
pressing the STOP key or allowing the GR8 to complete the
charging. When Top-O Mode is complete, the alarm sounds

every 30 seconds until you press STOP.

Chapter 6: Charging Menu—Diagnostic ChargingGR8 1100

Diagnostic Charge Results

The GR8 displays one of three battery decisions (GOOD
BATTERY, REPLACE BATTERY, REPLACE-BAD CELL) and an
analysis, which includes the battery State-of-Health (SOH).
Refer to the screen illustrations on this page.

Use the UP (p) or DOWN (q) ARROW keys to scroll to each
screen. To return to the Main Menu, press the EXIT soft key.
To print, press the PRINT soft key.

IMPORTANT: When you start a new test, the last

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

State-of-Health (SOH)

Another factor aecting 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. Based on
cranking rating, open-circuit voltage, conductance (ability to
deliver current) and battery temperature, the GR8 will not only
qualify a battery as “good” or “bad” (should be replaced), but
can also identify a “marginal” battery.

Although a State-of-Health problem can be the result of
defects in construction, it 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.

GOOD BATTERY Return the battery to service.

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.

WARNING: Charging a battery with a bad cell is dangerous!

Manual Charging

The GR8 charges the battery based on the current limit or
voltage limit, and charge duration that you select. Because
the charger makes no battery test decisions in this mode, it
does not produce a test code.

CAUTION: You must monitor the battery’s State-of-Charge

(SOC) and temperature to avoid overcharging. Any

charging after the battery is fully charged can result in
excessive battery temperature, which will “gas” the bat­tery and boil o electrolyte, shortening battery life.

Customer Service at 1.800.776.1995.

MESSAGE EXPLANATION

System Noise
Detected

Unstable Battery
Detected

The GR8 has detected computer, ignition noise, or parasitic drain, and will attempt to retest. Make
sure all vehicle loads are off, doors are closed, and the ignition is in the off position. The GR8 will
automatically retest when it no longer detects system noise. If the message reappears:

• You may be testing too close to a noise source, such as a charger or other high-current

device. If so, move away and retest.

• If you are unable to nd the source of the noise, fully charge the battery and retest. If the

message appears after recharging, test the battery out of the vehicle.

• Disconnect the battery cables and retest.

A battery that is weak, or that has just been charged, may retain enough electrical activity to
be detected by the GR8 and will adversely affect the test results. A fully charged battery should
stabilize quickly, after which the GR8 will automatically retest. Weak batteries should be charged
and retested. If the battery is fully charged, check the clamp connections.
