WARNING – Risk of Explosive Gases
1. WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE
EXPLOSIVE GASSES DURING NORMAL OPERATIONS AND, AT AN EVEN HIGHER LEVEL,
DURING CHARGING. IF ANYTHING IS ALLOWED TO IGNITE THESE GASSES, THE BATTERY
MAY EXPLODE, SENDING PIECES OF THE BATTERY AND EXTREMELY CAUSTIC BATTERY ACID
OUT IN ALL DIRECTIONS AND WITH EXTREME FORCE. SINCE JUST THE SLIGHTEST SPARK
IS SUFFICIENT TO IGNITE THESE GASSES, IT IS OF UTMOST IMPORTANCE THAT YOU READ
THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY, BEFORE USING YOUR BATTERY
CHARGER.
2. NEVER operate this battery charger near any fuel tanks or gas cylinders. This charger can produce
sparks that could ignite gasses and cause an explosion.
3. NEVER attempt to permanently mount this battery charger on a marine or recreational vehicle.
4. NEVER attempt to connect this charger’s output cables directly to the battery(s) in the bilge or
engine compartment of a boat. Follow the boat manufacturer’s battery charging instructions exactly.

INTRODUCTION
Description
This battery charger is designed to handle the majority of your charging and starting needs. It features:
• Automatic Multi-Phase Charging mode for easy operation.
• The ability to properly charge multiple battery types, including Flooded, AGM and Spiral Wound batteries.
• Multiple Charge Rates for various battery sizes.
• High-Amperage Engine Starting Assistance to start vehicles when the battery is weak.
• A stable power mode to maintain vehicle system voltage during on-vehicle repairs.
• Large Saw-Tooth Clamps assure good connection to top or side-mount battery terminals.
• Heavy-Duty Construction for long, trouble-free life.
How Batteries Charge
A battery charger does not force current into a battery – it makes a specific amount of current available to the
battery and the battery draws as much of it as it needs, up to or slightly greater than the rated output current
capability of the charger.
The closer a battery is to zero capacity (dead battery), the more charging current it will want to draw. When
charging begins, on a dead battery, the charger will typically supply current at or very near the nominal chosen
charging rate, and then move to a reduced rate of current as the battery becomes more fully charged. Keep in
mind, a charger’s display shows the amount of current being drawn from the charger by the battery, not what the
charger is capable of delivering.
Note: A slow, intermittent bubbling sound may be heard coming from the battery during the charging process.
This is a normal condition and just another indicator the battery is being charged.
To reduce the risk of battery overcharging, it is important to thoroughly read this entire instruction manual.
How Stable Power Mode Functions
Your unit features 3 separate working modes: automatic battery charging mode, stable power mode, and engine
start mode.
Stable Power mode is used to hold the voltage of the electrical system on a vehicle at a constant voltage for
various service/maintenance functions. These include on-vehicle repairs of electronically controlled systems,
diagnosis of electrical system component function or other applications where it is detrimental for the system
voltage to drop below a specific threshold.
In stable power mode, your unit will provide power to the vehicle’s electrical system so that system voltage
remains at a steady level (as directed by you during stable power mode set-up) despite load changes the system
experiences up to 60A (12V mode) 20A (24V mode) over an extended period of time.
NOTE: Stable power mode utilizes the vehicle’s battery to improve response times to load changes. As such, it
is important to ensure the vehicle’s battery is in good condition and fully charged prior to initiating stable power
mode.
Spark Prevention
Make sure no sparks or flames occur near the battery, especially during charging. It takes very little to ignite the
explosive gasses produced by a lead-acid battery during the charging process. Read, understand and follow the
safety information provided in the Safety Summary section of this manual before attempting to work with or near a
lead-acid battery.

initially at lowest rate.
The Ability to Charge Multiple Battery Types
Traditional battery chargers utilize basic charging controls that make them appropriate for charging only
Conventional and Maintenance Free Flooded (wet) Cell batteries. Use of traditional battery chargers on AGM or
other modern batteries results in suboptimal charging and potential harm to the battery being charged.
PRO-LOGIX Charger models utilize advanced charging technology to deliver precise charge controls, enabling them
to properly charge a wide variety of battery types.
Soft Start Mode and Battery Repair Mode
PRO-LOGIX Charger models utilize a proprietary advanced Multi-Phase charging process designed to optimally
charge many types of batteries. One critical aspect of this proprietary process is the precise control achieved
through the charging process, enabling the charger to monitor a battery’s specific reaction to the power supplied.
The PRO-LOGIX charging process includes a Soft Start Mode to properly charge deeply discharged batteries and
ensure that the energy from the charger is being properly incorporated into the battery. It also includes a Battery
Repair Mode to attempt to restore batteries that do not properly accept charging current. The display will indicate
BATTERY REPAIR by flashing the CHARGING LED and and monitor current acceptance by the battery. Battery
charging time will be extended to allow the battery to recover. Both processes are fully automatic and require no
intervention on the part of the operator, either to initiate the process or complete it.
Locating the Charger
1. Locate the charger as far away from the battery as DC cables permit.
2. Never allow battery acid to drip on the charger when reading specific gravity or filling the battery.
3. Do not operate the charger in a closed area or restrict ventilation in any way.
4. Ensure that there that there are no obstructions to the air flow, so the internal fans can properly cool the unit.
5. Do not set a battery on top of the charger.
6. Do not place the charger where rain, snow, or other moisture could drip on it.

maintain system voltage during on-vehicle
repairs and other applications where it is
detrimental for system voltage to drop below
a specific threshold. ENGINE START mode provides engine starting assistance to jump start vehicles with
depleted batteries.
SUPPLY (Stable Power) Control Buttons
Once an operator chooses SUPPLY Mode, they are able to select the desired system voltage to be maintained.
Desired voltage can be increased or decreased in 0.1V increments
CHARGE Control Buttons
Once an operator chooses CHARGE Mode, there are additional settings that must be chosen prior to
commencing the charging sequence.
The Type button allows an operator to choose the specific battery type to be charged, enabling the charger
to provide the exact power profile for that battery type. Selectable battery types include traditional flooded
batteries and AGM batteries (including Spiral Wound batteries).
The Volt button allows the operator to choose the desired voltage for the specific application. Selectable
voltages include 12V and 24V.
The Rate button allows an operator to choose the desired charge rate for each specific application. Selectable
charge rates include 60A, 40A or 10A charge rates (12V mode), 20A and 10A charge rates (24V mode)..
START Button
The START button is used to commence each function once all of the functional parameters have been set to
the desired values. The START button can also be used to discontinue any function once it has commenced.
LED Status Lights
LED lights in the control panel indicate which functional mode the charger is currently set to, as well as current
status of the chosen function once the function has commenced. In addition, each function mode features

CONTROLS AND INDICATORS

11
Choosing a Charging Rate
Choose a charging rate that is appropriate for the size and type of battery being charged. Use the battery
manufacturer’s specific instructions or see the guidelines below.
Typical rates are:
Small Motorcycle/Powersport 5 Amps or less (not applicable to this charger)
Lawn Mower/Tractor 5 Amps or less (not applicable to this charger)
Deep Cycle 15 Amps or less
Maintenance Free Automotive or Marine Cranking 40 Amps or less
Heavy Duty Commercial 60 Amps or less
Do not exceed the maximum charge rate recommended by the battery manufacturer or the chart above.
Choosing a Battery Type Setting
PRO-LOGIX Charger models utilize advanced charging technology to deliver precise charge controls, enabling them
to properly charge a wide variety of battery types.
• For Conventional and Maintenance Free Flooded (wet) Cell batteries: Choose STANDARD (STD).
• For AGM batteries: Choose AGM.
• For Spiral Wound Batteries: Choose AGM.
For batteries identified as Deep Cycle or Marine batteries, determine the construction of the battery. Is it a Wet cell,
AGM or Spiral Wound type of construction? Battery construction will determine the proper battery type selection.
Pre-Charge Battery Activation
Some modern batteries can cause charging problems if they have been deeply discharged. The plates in these
batteries can begin sulfating quickly, forming a barrier to accepting a charge. This condition will be indicated
by an extremely low (or zero) ammeter reading, indicating that the battery is not accepting current from the
charger. A deeply discharged battery such as this may take as long as 4 to 8 hours before it will accept a charge.
The Automatic Charging mode attempts to detect batteries with this condition (see Battery Repair Mode in
PREPARATION) and automatically adjusts for it.

Battery Type button until the “STD” LED is lit. To charge AGM and Spiral Wound batteries, push the Battery
Type button until the “AGM” LED is lit.
2. Choose a battery charging rate. Please see Choosing a Charge Rate section for general details related to
choosing a charging rate for your application.
3. Press the START button and the charging indicator LED will light. The charger will automatically commence
and complete the charging process. If you press the START button at any point during the charging sequence,
the charger will stop charging and return to Standby Mode.
Note: If the ERROR LED lights, disconnect from AC power immediately and determine the cause of the issue. See
Additional Features for a list of conditions that might cause an error.
Note: The charger is designed to protect against faults and shorts (see Battery Charger Features). If the battery
to be charged has a open circuit voltage of less than 1V, the charger will indicate a fault. If, after unplugging unit,
checking connections and verifying all settings, you determine the problem causing the “fault” condition is battery
voltage below 1V, you can override the charger’s protection by holding down the “START” button for 3 seconds.
The charger will commence the charging sequence and, assuming these are no other hindrances that caused the
fault indication, will complete the charging process and automatically turn off when the battery has reached full
charge.
4. When the battery approaches full charge and enters the Completion Phase, the green CHARGING COMPLETE
indicator will light and the CHARGING indicator will flash. At this point, if time is critical, the battery can be put
into service if it will be used in a charging situation, such as in a vehicle that that will be used immediately. To
reach a true 100% state of charge, the charger should stay connected until the charger reaches the Rest Phase,
when only the green CHARGING COMPLETE LED is lit.

5. After charging is complete, press the START button to return the unit to Standby Mode, turn off the Master Power
Switch and unplug the charger from the AC power source. Then, disconnect the charger clamp not connected
directly to the battery first and DO NOT allow the clamp to touch anything. Then, disconnect the charger clamp
attached to the battery terminal. (See Connecting To Batteries... at the beginning of this section.)
Stable Power Mode Operation
ATTENTION: Do not plug the charger power cord into the AC power source or set any of the charger’s controls
until told to do so in the following instructions.
ATTENTION: Connect and disconnect DC output clamps only after setting the power switch to the “OFF” position
and unplugging the AC cord from electric outlet. Never allow clamps to touch each other.
ATTENTION: Do not operate the charger in a closed area or restrict ventilation in any way. Ensure that there that
there are no obstructions to the air flow, so the internal fans can properly cool the unit.
Make a proper battery connection (see Connecting to a Battery in a Vehicle Section) and plug AC power cord into
an AC receptacle. Then, turn the master power switch located on the back of the unit to ON. The charger is now in
Standby Mode.
In order to place the unit into Stable Power Mode, toggle the Mode Selection button until the SUPPLY LED is
lit. If an ERROR Indicator LED lights, disconnect from AC stable power immediately and determine the cause of
the alarm. The POLARITY light indicates reverse polarity error connection, while the ERROR light indicates the
detection of a battery fault, such as a shorted connection.
NOTE: Make sure that the vehicle battery is in good condition and fully charged. A compromised battery can
jeopardize your diagnostic or repair efforts.. The unit will not commence the Stable Power mode if the vehicle
battery is below 12.0VDC. Charge the battery first to ensure it has capacity.
1. Choose the desired system voltage level. Using the UP/DOWN arrows in the Stable Power mode voltage control
zone, set the system voltage level on the display to the desired voltage.
2. Press the START button. The charger will bring system voltage to the desired level and hold it at that level,
providing power as needed (60A in 12V mode, 20A in 24V mode) to the vehicle to maintain the desired level. If
you press the START button at any point during the Stable Power sequence, the charger will stop charging and
return to Standby Mode.
3. After the Stable power session is complete, press the START button to return the unit to Standby Mode,
turn off the Master Power Switch and unplug the charger from the AC power source. Then, disconnect the
charger clamp not connected directly to the battery first and DO NOT allow the clamp to touch anything. Then,
disconnect the charger clamp attached to the battery terminal. (See Connecting To Batteries... at the beginning
of this section.)

Engine Starting
This battery charger can provide a high-current output to help start a 12V vehicle with a weak battery. However,
the onboard computer in some vehicles can be damaged when attempting to jump start. ALWAYS READ THE
VEHICLE OPERATOR’S MANUAL BEFORE AUXILIARY STARTING to determine if jump starting can do damage to
the vehicle. If not, read and follow these instructions.
CAUTION: Do not try to boost start a vehicle that does not contain a battery or you may damage electrical systems
in the vehicle.
1. Connect the battery charger to the vehicle according to the Connecting to a Battery Section of this
manual.
2. Charge the battery for 5 to 10 minutes at the appropriate charge rate for the size of battery.
3. In order to place the unit into Engine Start mode, toggle the Mode Selection button until the START LED is
lit. Press Start.
Note: The charger will enter Engine Start mode and stay in that mode for 30 seconds. If a start attempt is
not made within 30 seconds, the charger will return to standby mode.
4. Try to start the vehicle. If the vehicle doesn’t start after 3 to 4 seconds, stop and wait 3 to 4 minutes.
Repeat until engine starts.
5. After the engine start session is complete, press the START button to return the unit to Standby Mode,
turn off the Master Power Switch and unplug the charger from the AC power source. Then, disconnect the
charger clamp not connected directly to the battery first and DO NOT allow the clamp to touch anything.
Then, disconnect the charger clamp attached to the battery terminal. (See Connecting To Batteries... at the
beginning of this section.)
CAUTION: Excessive continuous engine cranking can damage vehicle starter motors.
Note: If the engine spins but fails to start after several starting attempts, there is an engine problem not related to the
starting system. Discontinue cranking the engine until the other problem is found and corrected.
This battery charger has an internal thermal protector to prevent overheating and damage to the battery charger.
After starting attempt, wait 3 to 4 minutes for the charger to cool. The thermal protector will automatically reset and
