1. USER SAFETY OPERATIONS GUIDE
Throughout this manual, look for this symbol. It means ‘BE ALERT –
YOUR SAFETY IS INVOLVED’. If you do not follow these safety
instructions, personal injury or property damage may occur.
WARNING –RISK OF EXPLOSIVE GASES.
WORKING WITH RECHARGEABLE BATTERY(s) IS DANGEROUS.
EXPLOSIVE GASES DEVELOP DURING NORMAL BATTERY OPERATION.
READ THIS MANUAL EACH TIME AND MAKE CERTAIN YOU FULLY
UNDERSTAND IT AND FOLLOW THE SAFETY AND OPERATING
INSTRUCTIONS AT ALL TIMES.
To reduce risk of battery explosion, follow all safety instructions below and
those published by the battery manufacturer. Review cautionary markings on
vehicle or equipment containing the battery.
CAUTION: To reduce the risk of injury, charge only rechargeable LEAD-
ACID batteries. Do not use battery charger for charging dry-cell batteries that
are commonly used with home appliances. These batteries may burst
causing personal injury and damage. If uncertain about battery type or
charging procedure contact the battery manufacturer. The charger is not
intended to supply power to low-voltage electrical systems other than
applications using rechargeable lead-acid type batteries
Use of an attachment not recommended or sold by the battery charger
manufacturer may result in a risk of fire, electric shock or injury to persons.
Do not operate this charger if it has received a sharp blow, was dropped or
otherwise damaged in any manner. Refer to a qualified service agent.
Charger contains no serviceable parts. If it fails during its warranty period,
contact your dealer to obtain a warranty replacement.
To reduce risk of electric shock, unplug charger from AC outlet before
attempting any maintenance or cleaning.
For external cleaning use a clean damp towel.
Have your distributor, dealer or other qualified service agent, repair or
replace worn or damaged parts immediately. Repairs should not be
attempted by people who are not qualified.
Whenever removing AC Plug from the receptacle, pull from the Plug Body;
not from the cord.
Do not operate the charger if it is malfunctioning. Personal injury or property
damage could result.
Locate charger as far away from battery as DC cables permit and never
allow DC output terminals to touch each other.
Never place charger directly above battery being charged; gases from

2. PERSONAL PRECAUTIONS WHILE WORKING WITH BATTERIES
Have someone within range of your voice to come to your aid if needed.
Have plenty of fresh water and soap nearby in case battery acid contacts
your skin, clothing or eyes. Wear eye and clothing protection and avoid
touching eyes.
If battery acid contacts skin or clothing, wash immediately with soap and
water.
If acid enters eye, immediately flush eye with running cold water for at least
10 minutes. Get medical attention immediately.
NEVER smoke or allow a spark or flame in vicinity of battery.
Be extra cautious not to drop a metal tool onto battery. It might spark or short
circuit battery or other electrical part that may cause an explosion.
Remove personal metal items such as rings, necklaces, watches, etc.
Batteries can produce a short-circuit current high enough to weld such items
causing a severe burn.
NEVER charge a frozen battery. Thaw it out for safer and more efficient
charging.
Be sure area around battery is well ventilated while battery is being charged.
Gas can be forcefully blown away using a non-metallic material like
cardboard.
Clean battery terminals. Be careful to keep corrosion from coming into
contact with eyes.
Add distilled water in each cell until battery acid reaches level specified by
battery manufacturer. This helps purge excessive gas from cells. Do not
overfill. For a battery without caps, carefully follow manufacturer's recharging
instructions.
Study all battery manufacturer's specific precautions such as removing or not
removing cell caps while charging and recommended rates of charge.
Determine voltage of battery by contacting battery manufacturer and make
sure it matches output rating of battery charger.
Do not use this charger for charging or maintaining more than one
Rechargeable Battery per Channel.
If problems arise connecting the output leads to the Rechargeable Battery,
contact the dealer where charger was purchased to obtain a suitable
connection device for your application.
WARNING: CHARGERS CAN IGNITE FLAMMABLE MATERIALS AND
VAPORS. DO NOT USE NEAR FUELS, GRAIN DUST, SOLVENTS, OR
OTHER FLAMMABLES. TO REDUCE THE RISK OF AN ELECTRIC SHOCK,
KEEP THE CHARGER DRY. DO NOT EXPOSE IT TO RAIN OR WATER.
3. A.C. AND UTILITY REQUIREMENTS
The use of an improper extension cord could result in a risk of fire or electric
shock. If an extension cord must be used, it must be UL and/or CSA
approved. Locate all cords so that they will not be stepped on, tripped over or
otherwise subjected to damage or stress. Extension cord must be properly

5
wired and in good electrical condition, and large enough for the AC rating of
charger as specified in this TABLE:
RECOMMENDED MINIMUM AWG SIZE FOR
EXTENSION CORDS FOR BATTERY CHARGERS
Length of cord (feet): 25 50 100 150
AWG size of cord: 18 18 18 18
Refer to the Product ID Label affixed to the product and identify the input
requirements such as ‘120Vac, 60Hz, 10Amps’. Ensure that the product will
be connected to a matching utility power rating. For example; if product is
rated at 60Hz, do not connect to a 50Hz utility.
Do not connect product to AC receptacles that share power with any other
moderate to heavy loads such as air conditioners, motors and other common
appliances. Most appliances turn on/off at random and cause power surges
and power droops that can severely affect the product connected to that
same power circuit.
Inspect AC Receptacles for general wear, including loose or hanging
receptacles and be very aware of potentially worn contacts. If any heat is felt
in and around the receptacle while the charger is operating, this is an
immediate indication of danger caused by a worn receptacle.
4. SAFE GROUNDING INSTRUCTIONS
Do not remove Ground Pin from charger’s Power Supply AC Plug, or connect
to utility power via an adaptor that bypasses the product’s ground pin
connection. The product must be grounded at all times when connected to
utility power.
This battery charger’s Power Supply must be grounded to reduce the risk of
electric shock. The Power Supply is equipped with an AC cord set having an
equipment-grounding conductor. This AC cord set must be connected to an
appropriate receptacle that is properly installed and grounded in accordance
with the National Electrical Code and all local codes and ordinances.
WARNING: IMPROPER CONNECTION OF THE EQUIPMENT-
GROUNDING CONDUCTOR CAN RESULT IN A RISK OF AN ELECTRIC
SHOCK.
The conductor with insulation having an outer surface that is green, with or
without yellow stripe(s), is the equipment-grounding conductor. If repair or
replacement of the charger’s AC cord set is necessary, refer to a qualified
service agent, and do not connect the equipment-grounding connector to a
live terminal.
5. PREPARING TO CHARGE
WARNING: The product’s supplied Power Supply is matched to the
Charger Power Requirements and may only be replaced with a
Manufacturer’s Approved Power Supply.

WARNING: The CHARGE MODE setting affects all charge channels,
simultaneously. DO NOT mix battery types on various charge channels. For
example, Large Capacity batteries cannot charge with Low Capacity
Batteries; nor may Lithium batteries be mixed with Lead Acid Batteries. The
MODE Select is accessed via the MENU button.
WARNING: Each Charge Channel may only be connected to a single
battery that is electrically isolated from all other batteries that may be
connected to other channels. For example, a 48V battery pack that is
comprised of (4) 12V batteries that are interconnected in an electrical
Series Configuration, such as those found in Golf Carts, may not be
connected to (4) 12V channels of this battery charger. Non-Warranty
Damage to the charger may occur.
AC and DC Cable Connections:
oConnect the Power Supply output cable to the chargers input Power
Jack located on the back side of the 10-Channel Charger.
oConnect the DC Cord Output Charge Cable(s) to any front side Output
Jack Charge Channel.
oThen connect the DC Cord’s Red Clamp to the Battery’s Positive (‘+’,
Pos.) Terminal and the DC Cord’s Black Clamp to the Battery’s Negative
(‘-’, Neg.) Terminal.
oReversing the output connection to a battery should be avoided but will
not damage the charger. When connected in reverse, charging will not
start –disconnect the charger clip connections from the battery and
remake the connections.
oApproximately 3 seconds after connection to a battery, the charger starts
its Multi-Stage charging process.
DO NOT connect more than one battery to a single channel.
DO NOT connect multiple outputs to a single battery or allow Red/Black clips
to touch each other.
DO NOT connect charge outputs to batteries installed in a battery pack
configuration, such as those found in golf carts and other similar applications.
Always plug output cords into charger first, then connect clips to battery
terminals.
Battery discharged to less than 2.4 volts will not pass the charger’s initial
battery test and that channel, consequently, may not turn on.
Dependent on a battery’s capacity and level of charge, it can take several
hours to days to fully charge/maintain battery.
The charger is factory preset to charge in MODE-1, optimizing it for SLI-Type
Automotive Batteries. Do not change this setting if the charger is being used
to charge typical car or truck batteries. If a more applicable setting is desired,
please consult the following Charge Mode Values And Setting Table below.

‘AH’ is an abbreviation for ‘Ampere-Hour’ and denotes the capacity rating of
the battery. For example, a battery rating of 32AH stores more energy and
has a higher energy capacity than an 18AH battery. These AH capacities
also help establish charge safety timer values, explained further in the next
section.
Lead Acid batteries are typically 2V per cell.
-12V Lead Acid batteries contain 6cells
-8V Lead Acid batteries contain 4cells
-6V Lead Acid batteries contain 3cells
*NOTE: The Absorption Value is listed as Volts Per Cell and is one of the
most important parameters pertaining to that charge algorithm. Different
batteries have differing number of cells –multiply the number of cells times
the ‘Volts-Per-Cell’ value to obtain the voltage the charger will regulate during
the Absorption Charge Stage. Two Examples are shown:
MODE-1 12V General Lead Acid has 6 Cells 2.400V x 6 Absorption = 14.40Vdc
MODE-25 4cell Lithium –‘Green’ has 4 cells 3.650V x 4 Absorption = 14.60Vdc
6. LED, LCD Display And Menu Button
LED Charge Channel Indicators:
Yellow Charge LED –illuminates continuously or flashes while charging
Green Charged LED –illuminates continuously when charge completes

Multi-Stage Charge Algorithms
There are up to 8 charging Stages! Depending on the MODE selected, these
stages are already preset and implementation of each stage will vary from one
CHARGE MODE setting to the next, dependent on the type of battery intended to
be charged. These charge stages ‘typically’ include:
PRE-QUALIFICATION-TEST Charge Stage:
Tests Lead Acid battery for sulphation by applying a low-level charge current
and analyzes voltage and current values and rates of change to determine if
the battery is ready to transition to the next high-power Bulk Charge Stage.
For Lithium cells, this stage is extremely brief and may not be annunciated. It
checks for minimum and maximum cell voltages. If a fully charged cell is
detected, a transition to ‘Charge Complete’ is done, bypassing all other
charge stages.
BULK Charge Stage (also known as ‘Constant-Current’):
High Power charge, charges at a constant current or constant power rate to
deliver the ‘bulk’ of the charge needed
Upon completion of this stage, approximately 80% of total charge is delivered
to the battery
ABSORPTION Charge Stage (also known as ‘Constant-Voltage’):
Charge voltage is held at a constant level to optimize the amount of energy
the battery absorbs.
Charge Amperage decreases as the energy is being absorbed.
Termination of this stage occurs when the charge current decreases to a
preset value. Duration of this stage is dependent on many factors such as
size, type, age, and chemistry of battery.
Upon completion of this stage, approximately 95% to 100% of total charge is
delivered to the battery.
TOP-OFF Charge Stage (also known as ‘Finish’):
Charger charges at either a constant voltage, or constant current, or a
combination of constant-current / constant voltage to ‘Top-Off’ the charge in
a battery.
This stage employs timing based on ‘timers’ measured and recorded during
previous charge stages, in combination with dv/dt and/or di/dt.
