around batteries.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
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.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flush with running cold water for at least 10 minutes and get doctor’s attention.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short circuit the
battery or other electrical part that may cause an explosion.
7. Before working with a battery, remove personal metal items such as rings, bracelets, necklaces, watches,
etc. A battery can produce a short circuit current high enough to weld such items causing a severe burn.
8. Use charger for charging LEAD ACID batteries only. The GR-1 is not intended to supply power to a lowvoltage electrical system other than applications using rechargeable type batteries. Do not use battery
charger for charging dry-cell batteries commonly used with home appliances. These batteries may burst
and cause personal injury and property damage.
9. NEVER charge a frozen battery, thaw it out first. Charging will then be safer and more efficient.
PREPARING THE BATTERY
1. If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first.
Make sure all accessories in the vehicle are off so as not to cause an arc.
2. Use stud adapters on side-post and/or Truck batteries that are not in the vehicle.
3. Be sure area around battery is well ventilated while battery is being charged. Using a piece of cardboard
or other nonmetallic material as a fan can forcefully blow gas away.
4. Clean battery terminals. Be careful to keep corrosion from coming into contact with your eyes.
5. Add distilled water in each cell until battery acid reaches level specified by manufacturer. This helps
purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow the
manufacturer’s recharging instructions.
6. Study all battery manufacturers’ specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
7. Determine the voltage of the battery and make sure that the output voltage menu selection is set at the
correct voltage.
GR-1 LOCATION
1. Locate GR-1 as far away from battery as GR-1 cables permit.
2. Never place GR-1 directly above battery being charged; gases from battery will corrode and damage GR-
1.
3. Never allow electrolyte to drip on GR-1 when taking gravity readings or filling a battery.
4. Operate GR-1 only in well-ventilated area, free of dangerous vapors.
5. Store GR-1 in safe, dry location and maintain in perfect condition.
6. Do not set battery on top of GR-1 or where its acid might drip onto GR-1.
7. Locate charger so that the plug is accessible at all times.
DC CONNECTION PRECAUTIONS
1. Set the GR-1 switch in the O position and AC cord should be DISCONNECTED from electrical outlet
before you connect and disconnect GR-1 clamps. Never allow clamps to touch each other.
2. When attaching GR-1 clamps, be certain to make the best possible mechanical as well as electrical
connection. Clamps should be kept clean.

GR-1 FUNCTIONS
1. DIAGNOSTIC FAST CHARGE (12 V)
The GR-1 will control and monitor the entire charging session including: initial diagnostic testing, initial
diagnostic charging, data analysis, charging duration, charging level, charging rate, top-off charging (when
appropriate) and final diagnostic testing.
The GR-1 will perform a number of tests prior to the actual charging.
While performing these diagnostic tests, the display may show a moving
status bar.
If the GR-1 detects a defective battery it will stop and display one of
the following results: Replace Battery or Bad Cell Battery.
If the GR-1 detects that the battery has reached sufficient
state-of-charge and cold cranking amps it will stop and displays
the result: Good Battery
DIAGNOSTIC CHARGING
If the analysis finds a battery with insufficient state-of-charge, the
GR-1 briefly displays the measured voltage and available starting
current, and then begins the diagnostic charging mode.
This mode greatly enhances the GR-1’s ability to judge hard to
diagnose batteries.
The length of time required for diagnostic charging varies,
depending on the type of battery being charged. During this first
diagnostic mode (which does not exceed 4 minutes), the GR-1
keeps the user informed by displaying the following information:
Charging voltage, Charging current, remaining time to charge, charging mode, and the amount of charge put
back into the battery (shown in Ah).
This first diagnostic charging mode will detect whether the battery
is capable of accepting charge or not. Having detected this it will
proceed to the main Diagnostic Fast Charge mode.
The GR-1 alerts the user of this transition with a message and an
audible tone.
FAST CHARGING A BATTERY
The GR-1 controls the charging voltage and charging current based on its analysis of the diagnostic testing
data, diagnostic charging data and the battery information that was selected by the user. It continuously
monitors the battery and analyzes the charging progress during the entire timed automatic charging session.
In some cases, the GR-1 may find a battery to be defective before the end of the estimated time to charge. In
other cases, the GR-1 may detect that the battery accepted the charge more quickly than estimated. With
either case, the GR-1 will alert the user with an audible alarm and an appropriate message.
During charging, the GR-1 keeps the user informed by displaying
the following information: Charging voltage, Charging current,
Remaining time to charge, Charging mode and the amount of
charge put back into the battery (shown in Ah).
Note: If at any time the GR-1 needs to be stopped, press the
STOP button and the charging session will be aborted.
CHARGE COMPLETION
The Diagnostic Fast Charge session is complete when the
proper amount of charge is put back into the battery or the
remaining time to charge goes to zero. The GR-1 will then
perform its final diagnostic tests on the battery.
When the analysis is complete, the GR-1 will alert the user with an
audible alarm and will display the following information: battery
voltage, available current in CCA, total charging time, battery
condition, and the final amount of charge put back into the battery (Ah).
Details can be found on the print-out.

MESSAGES
1. The “Incorrect Voltage Error” message means that the user has
made an incorrect menu selection (e.g. selected 12V but
connected to 24V) or it means that the GR-1 was connected
across a battery voltage that the GR-1 is not rated for.
2. The “Overcurrent Error!” message means that a battery or
vehicle electrical system has tried to draw too much current from
the GR-1. Observe all ratings, limits, precautions and warnings.
Check all connections and GR-1 menu selections.
3. The “Part Number Corrupt!” message means that the information
for a particular JIS battery number is corrupt. Except for testing
with this JIS number, the GR-1 is fully functional. Obtain the actual
CCA rating for the battery and input this CCA value for “Battery
Rating” instead of using the JIS number.
4. The “Internal Memory Error” message means that an internal error
has occurred in the GR-1 and it should be sent back for service.
OPERATION
1. The ON/OFF switch is toggled to the on position but the GR-1 does not power-up.
a. Make sure the AC power cord is completely inserted into the AC outlet.
b. Make sure the AC outlet is live (check fuse or circuit breaker).
c. Check the AC power cord for damage.
2. The GR-1 is on, the clamps are connected per Instruction Manual, but the display still shows “Check Clamp
Connections”.
a. Make sure that both jaws of the charging clamp come in good contact with the connection point. “Check
Clamp Connections” will remain on the display, as long as half of one clamp is not making good contact.
3. The GR-1 is displaying messages in the wrong language.
a. See OPTIONS (4): Language.
