CAUTION

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 qualied

serviceman.

Do not disassemble charger; take it to a qualied 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

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 specied by battery
manufacturer. Do not overll. 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 specic

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.

• If using an extension cord, always connect to the battery charger rst, before

connecting to an electrical outlet. When disconnecting from an electrical out,

always disconnect from the electrical outlet rst. Make sure the electrical outlet

is a 120VAC GFCI (Ground Fault Circuit Interrupt) outlet.

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 specic 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 GEN Series battery chargers have 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 to the eyelet terminal connectors is approximately 67”. Allow
for at least 12” of slack in the battery connections. Thus, we recommend not to
extend the battery connections past 55”.

GEN Series

geniuschargers.com

USING GEN SERIES BATTERY CHARGERS USING GEN SERIES BATTERY CHARGERS

98

Make sure the mounting location has adequate strength to support the battery
charger. Use the battery charger mounting holes as a template to mark the
holes to be drilled. Drill the mounting holes and secure the battery charger
in the desired location with the screws and washers supplied. Use a silicone
sealer to waterproof the screw holes. Prepare the battery(s) before making
any connections. Make sure all battery terminals are clean and free of battery
corrosion.

BATTERY SPECS

The following recommendations should ONLY be considered as guidelines.
Always refer to the battery manufacturer’s recommendations for battery
charging. The GEN Series On-Board Battery Chargers are suitable for
charging all types of 12V lead-acid batteries, including Wet (Flooded), Gel,
MF (Maintenance-Free) and AGM (Absorption Glass Mat) batteries. The GEN
Series On-Board Battery Chargers can be used on battery sizes from 25 to
230Ah.

CONNECTING TO THE BATTERY

Before you connect to the battery(s), make sure that the AC power plug is
not connected to an electrical outlet. DO NOT CONNECT THE BATTERY
CHARGER AC POWER PLUG TO THE ELECTRICAL OUTLET UNTIL ALL

OTHER CONNECTIONS ARE MADE. Make sure you have identied the

correct polarity of the battery terminals on the battery(s). The POSITIVE
battery terminal is typically marked by these letters or symbols (POS,P,+).
The NEGATIVE battery terminal is typically marked by these letters or symbol

(NEG,N,-). If you are having difculty determining the polarity of the battery

terminals, contact the battery manuafcturer before proceeding.

1.) Connrm that you have a 12V battery(s). This battery charger is for 12V

LEAD-ACID BATTERIES ONLY.

2.) Connect the POSITIVE (Red) battery eyelet terminal connector to the
POSITIVE (POS,P,+) battery terminal.

3.) Connect the NEGATIVE (Black) eyelet terminal connector to the NEGATIVE
(NEG,N,-) battery terminal.

4.) Repeat steps 2 and 3 for each battery.

HOW TO START CHARGING

1.) Conrm that you have connected the eyelet terminal connectors properly.

2.) Connect the battery charger’s AC power plug into a suitable electrical outlet.

DO NOT FACE THE BATTERY WHEN MAKING THIS CONNECTION.

3.) Charge battery(s) until fully charged. A Green LED will illimunate when the
battery is fully charged.

UNDERSTANDING CHARGE LEDS

Each battery bank contains two (2) CHARGE LEDs - Red and Green. The
CHARGE LEDs indicate the charging process or an ERROR condition. To
understand the CHARGE LEDs, see the chart below:

CHARGE LED EXPLANATION

Charging LED

Charged LED

ERROR LEDS

When the battery is charging, a single Red CHARGE
LED will illuminate. The CHARGE LED will remain a
solid Red color (not blinking) until the battery is fully
charged. The Red CHARGE LED is always left of the
Green LED.

When the battery is fully charged, a single Green
CHARGE LED will illuminate. The CHARGE LED
is remain solid (not blinking) until either the battery
charger is disconnected or the battery becomes
discharged. The Green CHARGE LED is always
Right of the Red LED.

If an ERROR condition exists, both CHARGE LEDs

will illimunate and will ‘ash’ back and forth at 5Hz.

There are several reasons an ERROR condition could
exist, for help trouble shooting ERROR conditions,
see the section entitled TROBLESHOOTING.

WICKED SMART TIP

The battery charger will not begin delivering any current to the battery(s)
until the battery charger detects a ‘stable’ battery. A ‘stable’ battery means
the eyelet terminal connectors are connected to the battery with the
correct polarity (POSITIVE-TO-POSITIVE, NEGATIVE-TO-NEGATIVE)
and have a tight, clean connection to the battery being charged. If the
battery is not stable for at least thrity (30) seconds, the battery charger
will not begin charging the battery and the battery charger will go into
an ERROR condition. If the battery is connected in reverse polarity, it

is considered an ‘unstable’ battery and the ERROR LEDS will ash until

the ERROR is cleared by reversing the eyelet terminal connectors. If
the eyelet terminal connectors are disconnected at any point during the
charging cycle, the battery charger will turn ‘off’ to help eliminate any
possibility of spark. Similiarly, if the eyelet terminal connectors are loose
and making intermittent contact, the battery charger will turn ‘off’ to help

eliminate any possibility of spark. That’s Smart, Wicked Smart.™

CHARGING STEPS

Step 1 & 2: Diagnostics

Checks battery voltage to make sure battery connections are good & battery is in a
stable condition.

Step 3: Soft Start

Begins Bulk charging process with a gentle (soft) charge.

Step 4-5: Bulk

Continues Bulk charging process, returns 80% of battery capacity.

Step 6: Absorption

Brings the charge level to 90%. The battery charger will deliver small amounts of

current to provide a safe, efcient charge and limit battery gassing.

Step 7: Trickle

Battery is fully charged and ready to use, indicated by the CHARGE LED being
a solid Green. In this step, the battery charger will only deliver enough current to
keep the battery full. If the battery tells the charger that more current is needed, the
battery charger will switch to Maintenance.

CHARGING TIMES

The time required for the GEN Series to charge a normally discharged battery
is shown below. Deeply discharged batteries may take longer to charge
depending on the depth of discharge (DOD). The charge time is based on an
average depth of discharge to a fully charged battery.

MAINTENANCE

GEN Series battery chargers do not require any maintenance. Do not attempt
to open or repair the battery charger as it will invalidate the limited warranty.
A damp cloth may be used to clean dust, dirt, or other debris off of the battery
charger. BEFORE ATTEMPTING TO CLEAN THE BATTERY CHARGER,
MAKE SURE YOU REMOVE THE AC POWER PLUG FROM THE POWER
SOURCE.

Step 8: Maintenance

Continuously monitors the battery voltage to determine if a maintenance charge
should be initiated. If the terminal voltage falls below 12.8V, the charger will start
the Maintenance cycle until voltage reaches 14.4V and then discontinues the

charge cycle. The cycle between Trickle and Maintenance is repeated indenitely

to keep the battery at full charge, without overcharging. The battery charger can be

left connected indenitely.

WICKED SMART TIP

RIPPLE. Describes the disturbances by current and voltage. A ripple

voltage may cause damage to other equipment connected to the battery.
Less than 2% is wicked low, which will help increase battery life and
protect equipment from damage.

TROUBLESHOOTING

TROUBLESHOOTING

1716

WHEN FLASHING LEDS ILLUMINATE

When the battery charger detects an ERROR condition, the CHARGE LEDs

will ash back and forth. If you are seeing this ERROR condition, it could be the

result of one of the following situations:

• BATTERY VOLTAGE INCOMPATIBILITY

Check to make sure you have a 12V battery. This battery charger is for 12V
batteries only. If you attempting to charge a battery that is other than 12V, it
could cause this ERROR condition. Charge the appropriate battery to resolve
this ERROR condition.

• SULFATED, DAMAGED, OR POOR BATTERY

This ERROR condition can be the result of a sulfated, damaged, or poor
battery. To properly diagnose a sulfated, damaged, or poor battery, take the
battery to a local battery store for an evaluation. If you have checked all other
possible ERROR conditions and cannot clear the ERROR, it is probably the
result of a sulfated, damaged, or poor battery.

• LOW VOLTAGE BATTERY
If the battery voltage is below 2.0VDC (12V), it could cause this ERROR
condition. See the section entitled “LOW VOLTAGE BATTERY” below to
resolve this ERROR condition.

• Abnormality Protection

This ERROR condition is the result of the battery charger being in the Bulk
mode for more than twenty-four (24) hours. This ERROR condition is the result
of a bad battery. To resolve this ERROR condition, take the battery to a local
battery store for an evaluation.

• CORROSION ON BATTERY TERMINALS

Check the battery connections for battery corrosion. If battery corrosion is
present on the battery connections, it could cause this ERROR condition.
Remove the battery corrosion to resolve this ERROR condition.

• LOOSE BATTERY CONNECTIONS

Check the battery connections to the battery. If the battery connections are
loose, it could cause this ERROR condition. Tighten the battery connections to
resolve this ERROR condition.

WHEN NO LIGHTS COME ON WHEN THE BATTERY CHARGER IS
PLUGGED INTO AN ELECTRICAL OUTLET

• POOR AC CONNECTION

Check if the AC outlet has power. If the AC outlet has no or limited power, it
could cause this condition. Plug a light into the AC outlet to check if the outlet
has power. If the light is extremely dim, this could be the result of limited AC
power. The battery charger is designed for use at 70-130VAC. If there is no

power or the power is below 70VAC, locate another AC outlet that has sufcient

power to resolve this ERROR condition.

LOW VOLTAGE BATTERY

If the battery voltage is below 2.0VDC (12V), an ERROR conditon will occur

and the CHARGE LEDs will ash back and forth, indicating the battery is out

of range for the battery charger. In this situation, the battery charger has
determined that the battery voltage is too low to begin a normal charge cycle.
To increase the battery voltage and allow the battery charger to begin charging,
you will need to jump start the battery.

• BLOWN FUSE IN BATTERY CONNECTOR HARNESS

Check the fuse in the battery connector harness. If the fuse in the battery
connector harness has blown, it could cause this ERROR condition. Replace
the fuse with a 15A Automotive Blade Fuse to resolve this ERROR condition.

TESTING TO SEE IF CHARGER IS CHARGING

Before applying AC power to the charger, measure the battery voltage with
a digital voltmeter and write the value down. Plug the battery charger into
an electrical outlet. Wait at least thirty (30) seconds and measure the battery
voltage again with the digital voltmeter. The battery voltage should be higher
than the previous value and slowly moving up.

GEN Series

geniuschargers.com

WICKED SMART TIP

If you have a severely discharged battery, a battery that is below

9.0VDC, it could be the result of a defective battery. Batteries that have
been severely discharged as a result of an accidental load should
respond quickly when current is applied to the battery, resulting in a
sharp increase in battery voltage.
