IMPORTANT SAFETY INSTRUCTIONS - READ THESE FIRST
A
WARNING
Read these instructions completely before using the Battery Charger and save them for future
reference. Before using the Battery Charger to charge a battery, read these instructions and the
instruction manual/safety information provided by the car, truck, boat or equipment manufacturer.
Following all manufacturers’ instructions and safety procedures will reduce the risk of accident.
Working around lead-acid batteries may be dangerous. Lead-acid batteries release explosive gases
during normal operation, charging and jump starting. Carefully read and follow these instructions for
safe use. Always follow the specific instructions in this manual and on the Battery Charger each time
you use the Battery Charger.
All lead-acid batteries (car, truck and boat) produce hydrogen gas which may violently explode in the
presence of fire or sparks. Do not smoke, use matches or a cigarette lighter while near
batteries. Do not handle the battery while wearing vinyl clothing because static electricity sparks are
generated when vinyl clothing is rubbed. Review all cautionary material on the Battery Charger and
in the engine compartment.
This battery charger is equipped with a setting for charging a specific type of lithium battery
chemistry, Lithium Iron Phosphate (LiFePO4). The charger's lithium charging function is optimized
for this type of lithium battery only, as noted on the control panel. There exist many different lithium
battery types, each using a different specific lithium battery chemistry. Do not charge any other
lithium battery types using this charger – doing so could result in personal injury and/or property
damage.
Always wear eye protection, appropriate protective clothing and other safety equipment when
working near lead-acid batteries. Do not touch eyes while working on or around lead-acid batteries.
Always store clamps away from each other or common conductors. Improper storage of clamps may
cause the clamps to come in contact with each other, or a common conductor, which would be
hazardous if the Battery Charger was plugged into an AC outlet.
Use extreme care while working within the engine compartment, because moving parts may cause
severe injury. Read and follow all safety instructions published in the vehicle's Owner's Manual.
Batteries being charged with the Battery Charger unit likely contain liquid acids which are hazardous
if spilled.

cleaning. Turning off controls will not reduce this risk.
11. Monitor battery charger daily when using it to maintain
battery for extended periods.
12. WARNING – RISK OF EXPLOSIVE GASES.
a. 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 each time before using
your charger, you read this manual and follow the
instructions exactly.
b. To reduce risk of battery explosion, follow these
instructions and those published by the battery
manufacturer and the manufacturer of any
equipment you intend to use in the vicinity of the
battery. Review cautionary markings on these
products and in the engine compartment.
1. Someone should be within range of your voice or
close enough to come to your aid when you work near
a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case
battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection.
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 flood eye with cold running water
for at least 10 minutes and get medical attention
immediately.
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 battery
or other electrical part that may cause explosion.
7. Remove personal metal items such as rings,
bracelets, necklaces, and watches when working with
a lead-acid battery. A lead-acid battery can produce
a short-circuit current high enough to weld a ring or
other jewelry to metal, causing a severe burn.
8. Use charger for charging LEAD-ACID and LiFePO4
batteries only. It is not intended to supply power to a
low voltage electrical system other than in a starter-
motor application. Do not use battery charger for
charging dry-cell batteries that are commonly used
with home appliances. These batteries may burst and
cause injury to persons and damage to property.
9. NEVER charge a frozen battery.

BATTERY CHARGING SETTINGS
Upon making a proper battery connection (see Section
F or G as applicable), plug AC power cord into an AC
receptacle. All unit LEDs will light momentarily, then only
the LEDs corresponding to charging settings should stay
lit. The charger is now in Standby Mode.
If an ERROR Indicator LED lights, disconnect from AC
power supply immediately and determine the cause of the
alarm. A flashing ERROR light indicates reverse polarity,
while a solid ERROR light indicates the detection of a
battery fault, such as a shorted connection.
To charge a battery:
1. Choose a battery type setting. To charge Standard
and Maintenance Free Flooded Acid batteries, push
the 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. To
charge Lithium Iron Phosphate starting batteries, push
the Battery Type button until the “LiFeP04” LED is lit.
Note: When charging lithium batteries, please
note that there are many different lithium battery
chemistries. The Lithium charging setting on this
charger is specifically for Lithium Iron Phosphate
(LiFePO4) batteries and only these lithium batteries.
The charger should never be used for charging any
other lithium battery type.
Note: Ambient temperature must be between 0C and
50C in order to charge a LiFePO4 battery. If ambient
temperature is outside this range, ERROR is solid and
LiFePO4 is flashing, and charging will not start.
2. Press the “CHARGE” button and the charging
indicator LED will light. The charger will automatically
commence and complete the charging process. If you
press the “CHARGE” 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
alarm. See Additional Features for a list of conditions
that might cause this warning.
Note: The charger is designed to protect against faults
and shorts (see Battery Charger Features). If the
battery to be charged has an 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
“CHARGE” button for 3 seconds. The charger will
commence the charging sequence and, assuming
there 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.
3. When the battery approaches full charge and enters
the Completion Phase, the green CHARGING
COMPLETE indicator will light and the CHARGING IN
PROGRESS 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 is lit.
4. When you are finished with the charging process,
disconnect AC power cord from AC outlet, then
disconnect DC leads from vehicle ground (if charging
with battery in vehicle) and battery in the reverse
sequence of the connection procedure.
Low Energy Consumption Mode
Note: The charger is designed to minimize energy
consumption as much as possible. If the unit is in
standby mode for 10+ minutes without a key pressed,
the TYPE LED will flash. If the unit is in charge mode
and has reached the rest phase, the CHARGED
LED will flash slowly. At any time, you can wake the
display by pressing any button.

CHARGING PROGRESS AND DISPLAY FEEDBACK
The charger uses a proprietary Multi-Stage charging process designed to optimally charge and maintain batteries.
Assuming normal battery health, the standard charging sequence has four stages: 1.) energizing, 2.) fast charge, 3.)
absorption, 4.) completion. Additionally, the charger has dedicated modes to address battery issues, as noted below.
Finally your charger is an ideal tool for battery maintenance, the steps for which are addressed below as phases 5-7.
ENERGIZING PHASE
The charging process includes an initial energizing mode in which the charger determines the best charging path for
the connected battery. From there, the charger can enter the Fast Charge stage (most cases), Soft Start Mode, Battery
Recondition Mode or stop the charging routine because unsafe battery conditions (short, etc.) are detected.
SOFT START MODE
Soft Start Mode is activated when the charger is connected to a deeply discharged battery. This mode protects the battery
during the initial charge period, as the battery’s voltage rises to a more normal level, and is beneficial for the long-term
health of the battery.
BATTERY RECONDITION MODE
During the Energizing Phase, if the charger detects the presence of battery sulfation, it will activate this mode. If this
occurs, the CHARGING LED will flash. This indicates the charge time will be extended while the charger attempts to
recondition the battery.
PRO-LOGIX PHASES 5-7: IDEAL BATTERY MAINTENANCE
A key feature of this charger is how it manages a battery that remains on the charger after a complete charge has been
achieved, such as during the storage of a seasonal use vehicle. Once the charger reaches the Resting Phase, its output
is virtually turned off, except to occasionally monitor battery condition. This is beneficial for the connected battery, as it
reduces chemical reaction within the battery compared to traditional charger maintenance modes. This greatly reduces the
chance of damaging a battery in long-term storage. In the resting phase, the charger will enter a low power mode, when
only the green “Complete” LED flashes slowly. To resume normal operation, press any key to reactivate the display.
In addition, in Phase 6 Exercising, we introduce a load on the battery, simulating active use, and then recharge the battery
to full charge. This Exercising feature keeps the battery in optimal condition during periods of storage and non-use.
ADDITIONAL FEATURES
MULTIPLE BATTERY COMPATIBILITY
The charger will properly charge a wide variety of battery types, including Conventional, Maintenance Free,
AGM, LiFe, Spiral Wound and Deep Cycle batteries.
SMART CLAMP TECHNOLOGY
The charger will send power to the output leads only when a proper battery connection is made.
REVERSE POLARITY PROTECTION
Guards against reverse connections. The ERROR LED will flash on the control panel and power will not be sent to output
cables if a reverse connection is sensed.
TEMPERATURE COMPENSATION
The charger is equipped with temperature compensation technology, which alters the charging parameters based on
ambient temperature. This is beneficial for battery health, as it is critical in achieving an optimal charge, as the battery’s
needs change based on temperature.
BATTERY FAULT PROTECTION
Guards against excessively charging compromised batteries. ERROR and CHARGING LED will flash indicating charging
has stopped and the charger has detected a compromised battery. Conditions that cause this error include: if the battery
voltage does not rise appropriately during the charging process (indicating a shorted cell) or if the maximum charge time
has been exceeded.
SHORT CIRCUIT PROTECTION
Guards against shorted connections. ERROR LED will light solid on control panel and power will not be sent to output
cables. This condition is triggered if the charger detects less than 1V across the clamps. See Operating Instructions Step
2 Note 2 for details regarding this feature.

CAUTION – Make sure charger is unplugged from
electrical outlet before performing any maintenance.
A minimum amount of care can keep your battery charger
working and looking good for years.
1. Clean the clamps after each use. Wipe off any battery
fluid that may have come in contact with the clamps
to prevent corrosion. Battery fluid may be neutralized
with a solution of water and baking soda.
2. If needed, the case may be wiped clean with a soft
cloth.
There are no user-serviceable parts inside.

CHOOSING THE BATTERY TYPE
I
OVER-VOLTAGE PROTECTION
Guards against charging errors where the charger is programmed to charge in a different voltage than the detected
voltage of the battery. When this safeguard is engaged, the ERROR LED will slowly flash (2.0s-ON/2.0s-OFF). To reset
the charger, disconnect from AC outlet, reset the vehicle connections and reconnect to the AC outlet.
For Conventional and Maintenance Free flooded (wet) batteries, the ideal Battery Type selection is “STD”.
For batteries identified as AGM construction, the ideal Battery Type selection is “AGM”.
For batteries identified as LiFe construction, the ideal Battery Type selection is “LiFeP04”.
For most Spiral Wound batteries, the best Battery Type selection is “AGM”.
For batteries identified as Deep Cycle, determine the construction of the battery. Is it a wet cell battery or another type of
construction? This will determine the proper Battery Type selection.
