WARNING
RISK OF EXPLOSIVE GASES
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS
DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL BATTERY OPERATION. FOR
THIS REASON, IT IS OF UTMOST IMPORTANCE THAT
YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU
USE THE CHARGER.
To reduce risk of battery explosion, follow these
instructions and those published by battery
manufacturer and manufacturer of any equipment
intended to be used in vicinity of battery. Review
cautionary markings on these products and on engine.
BATTERY POSTS, TERMINALS, AND RELATED ACCESSORIES CONTAIN
CHEMICALS, INCLUDING LEAD, KNOWN TO THE STATE OF CALIFORNIA TO
CAUSE CANCER AND BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.
ALWAYS WASH YOUR HANDS AFTER HANDLING THESE PRODUCTS.

CAUTION
Do not expose charger to rain or snow.
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.
To reduce risk of damage to electric plug and cord, pull by plug
rather than cord when disconnecting charger.
Do not operate charger with damaged cord or plug – replace the
cord or plug immediately.
Do not operate charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way; take it to a qualied
serviceman.
Do not disassemble charger; take it to a qualied serviceman
when service or repair is required. Incorrect reassembly may
result in a risk of electric shock or re.
To reduce risk of electric shock, unplug charger from outlet
before attempting any maintenance or cleaning. Turning off
controls will not reduce this risk.
DO NOT USE EXTENSION CORDS unless absolutely necessary. Using
an improper extension cord could result in a risk of re and electric
shock and may result in property damage, personal injury or death. If
extension cord must be used, make sure that:
1.) The pins on the extension cord plug have the same number, size,
and shape as those of the AC power cord plug on the charger.
2.) The extension cord is properly wired and is in good electrical
condition.
3.) The wire size is as specied in Table I below:

PERSONAL PRECAUTIONS
USE THE FOLLOWING PRECAUTIONS WHEN YOU WORK
NEAR LEAD-ACID BATTERIES:
• Someone should be within range of your voice or close enough to come to
your aid if you have an accident.
• Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes.
• Wear complete eye protection and protective clothing. Avoid touching your
eyes while working near a battery. If battery acid contacts your skin or clothing,
wash immediately with soap and water. If acid enters an eye, immediately ood
the eye with running cold water for at least ten (10) minutes and seek medical
attention as soon as possible.
• Be extra cautious when handling metal tools around a battery. If you drop
a metal tool near a battery it might spark or create a short circuit between
the battery terminals and some other metal part. Either event may cause a
dangerous electrical shock hazard, a re, or even an explosion, resulting in
property damage, personal injury, or death.
• Never smoke or allow an open spark or ame in the vicinity of the battery or
engine.
• Remove all personal items made of metal, such as, rings, bracelets,
necklaces, and watches when working with a lead-acid battery. A lead-acid
battery can produce a short-circuited current high enough to weld a metal ring
or other piece of jewelry, causing a severe burn.
• This battery charger is for charging LEAD-ACID BATTERIES ONLY. DO
NOT USE THE BATTERY CHARGER FOR DRY-CELL BATTERIES THAT
ARE COMMONLY USED WITH HOME APPLIANCES. THESE TYPES
OF BATTERIES MAY BURST AND MAY CAUSE PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
•NEVER charge a frozen battery.
BEFORE CHARGING
• To avoid an electric arc (or spark), turn off or disconnect all of the accessories
in the vehicle. Always remove the cable that is connected to grounded terminal
from battery rst.
• Make sure the area around the battery is well-ventilated while the battery is
being charged. If necessary, use a non-metallic material to blow away the gas
in the area.
• If necessary, clean the battery terminals. Be careful to keep the corrosion and
other debris from coming in contact with your skin or eyes.
• If the battery is not a sealed battery, add distilled water to each cell (if
necessary) until the battery acid solution reaches the level specied by battery
manufacturer. Do not overll. For a battery without cell caps, such as a valve
regulated lead-acid battery (VRLA), carefully follow the battery manufacturer’s
charging instructions.
• Before charging, carefully read the battery manufacturer’s specic
precautions and recommended rates of charge.
• Determine the voltage of the battery by referring to the vehicle’s owner’s
manual and make sure that the charge mode is set at the correct voltage.
• Connect and disconnect the DC output cables only after the battery charger is
placed in the STANDBY mode and the AC cord is removed from the electrical
outlet. Never allow the battery clamp or eyelet terminal connectors to touch
each other.
LOCATING BATTERY CHARGER
• Locate the battery charger as far away from the battery as possible.
• Never place the battery charger directly above the battery; gases from battery
will corrode and damage battery charger.
• When reading electrolyte specic gravity or ling battery, never allow battery
acid to come in contact with the battery charger.
• Do not operate the battery charger in a closed-in area or an area with
restricted ventilation.
• Do not set a battery on top of battery charger.
MOUNTING BATTERY CHARGER
The G3500 has four (4) external mounting holes in the casing of the battery
charger enclosure. These external mounting holes can be used to mount the
battery charger permanently in a desired location for battery charging. When
mounting the battery charger to a xed location, keep in mind the distance to
the battery from the battery charger. The cable length from the battery charger
with either the battery clamp or eyelet terminal connectors is approximately
72” (6’). Allow for at least 12” (1’) of slack in the battery connections. Thus, we
recommend not to extend the battery connections past 60” (5’).

BATTERY SPECS
The following recommendations should ONLY be considered as guidelines.
Always refer to the battery manufacturer’s recommendations for battery
charging. The G3500 is suitable for charging all types of 6V &12V lead-acid
batteries, including Wet (Flooded), Gel, MF (Maintenance-Free) and AGM
(Absorption Glass Mat) batteries and battery sizes from 1.2 to 120Ah (and 1.2
to 14Ah for small batteries). The battery charger can also maintain all battery
sizes.
CHARGE MODES
The G3500 is equipped with eight (8) charging modes: 6V NORM, 6V COLD/
AGM, 12V NORM, 12V COLD/AGM, SMALL 6V NORM, SMALL 6V COLD/
AGM, SMALL 12V NORM and SMALL 12V COLD/AGM. Before selecting a
charge mode, it is important to understand the differences and the purpose of
each mode. The charge modes are explained below:

The “normal” (“NORM”) charge mode is for charging
Wet Cell, Maintenance-Free and Gel Cell batteries. If
you are unsure of the chemistry of your battery, use
the NORM charge mode. When selected, a Red LED
will illuminate.
The COLD/AGM charge mode is for charging
batteries in cold weather and AGM (also known as
“spiral wound”) batteries. If a battery’s (Wet, Gel, MF
or AGM) temperature is below 32
COLD/AGM charge mode. If you are unsure of the
chemistry of your battery, DO NOT use this charge
mode, and use the NORM charge mode instead.
When selected, a Blue LED will illuminate.
The “normal” (“NORM”) charge mode is for charging
12V Wet Cell, Maintenance-Free and Gel Cell
batteries. If you are unsure of the chemistry of your
battery, use the NORM charge mode. When selected,
a Red LED will illuminate.

The COLD/AGM charge mode is for charging 12V
batteries in cold weather and AGM (also known as
“spiral wound”) batteries. If a battery’s (Wet, Gel, MF
or AGM) temperature is below 32oF (0oC), use the
COLD/AGM charge mode. If you are unsure of the
chemistry of your battery, DO NOT use this charge
mode, and use the NORM charge mode instead.
When selected, a Blue LED will illuminate.
The “normal” (“NORM”) charge mode is for charging
Wet Cell, Maintenance-Free and Gel Cell batteries. If
you are unsure of the chemistry of your battery, use
the SMALL NORM charge mode. When selected, a
Red LED will illuminate.
WICKED SMART TIP
Amp Hour (Ah) is a rating that measures a battery’s storage capacity.
The Ah rating indicates how much amperage is available in the battery
over a twenty (20) hour period. In order to determine how many constant
Amps the battery can output for 20 hours, divide the Ah rating by 20. For
example, if you have a 100Ah battery, it can deliver 5 Amps for 20 hours
before it is fully discharged (100 / 20 = 5).
Now That’s Smart, Wicked Smart.™
