may result in a SERIOUS INJURY, DEATH, or PROPERTY DAMAGE.
Electrical Shock. Product is an electrical device that can shock and cause serious injury. Do not
cut power cords. Do not submerge in water or get wet.
Explosion. Unmonitored, incompatible, or damaged batteries can explode if used with product.
Do not leave product unattended while in use. Do not attempt to jump start a damaged or
frozen battery. Use product only with batteries of recommended voltage. Operate product in
well ventilated areas.
Fire. Product is an electrical device that emits heat and is capable of causing burns. Do not
cover product. Do not smoke or use any source of electrical spark or fire when operating
product. Keep product away from combustible materials.
Eye Injury. Wear eye protection when operating product. Batteries can explode and cause
flying debris. Battery acid can cause eye and skin irritation. In the case of contamination of eyes
or skin, flush affected area with running clean water and contact poison control immediately.
Explosive Gases. Working in the vicinity of a lead-acid is dangerous. Batteries generate
explosive gases during normal battery operation. To reduce risk of battery explosion, follow all
safety information instructions and those published by the battery manufacturer and
manufacturer of any equipment intended to be used in the vicinity of battery. Review
cautionary markings on these products and on engine.
Important Safety Warnings
AXTRA car battery charger represents some of the most innovative and advanced technology

not attempt to use product with any other type of battery. Charging other Important Safety
Warnings and battery chemistries may result in injury, death or property damage. Contact the
battery manufacturer prior to attempting to charge the battery. Do not charge a battery if you
are unsure of the battery’s specific chemistry or voltage.
How To Use
Charging Modes.
Press to select the appropriate charging mode for battery. It is important to
understand the differences and purpose of each charge mode. Always check with
battery manufacturer to confirm the right charge mode for your specific battery.
Do not operate the charger until you confirm the appropriate charge mode for
your battery. Below is a brief description:
Standby: In Standby mode, the charger is not charging or providing any power to
the battery. Energy Save is activated during this mode, drawing microscopic
power from the electrical outlet. When in Standby, the green Standby LED will
illuminate.
Error : light will illuminate when an error condition or reverse polarity is
present.

Connecting to the Battery with Battery Clamps
Do not connect the AC power plug until all other connections are made. Identify
the correct polarity of the battery terminals on the battery. The positive battery
terminal is typically marked by these letters or symbol (POS,P,+). The negative
battery terminal is typically marked by these letters or symbol (NEG,N,-). Do not
make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The
below instructions are for a negative ground system (most common). If your
vehicle is a positive ground system (very uncommon), follow the below
instructions in reverse order.
1. Connect the positive (red) battery clamp or eyelet terminal connector to the
positive (POS,P,+) battery terminal.
2. Connect the negative (black) battery clamp or eyelet terminal connector to the
negative (NEG,N,-) battery terminal or vehicle chassis.
3. Connect the battery charger into a suitable electrical outlet. Do not face the
battery when making this connection.
4. When disconnecting the battery charger, disconnect in the reverse sequence,
removing the negative first (or positive first for positive ground systems).

Quick-Connect O-Ring Terminal
The O-ring connectors permanently attach to the battery, providing easy access to
quickly connect the charger to your battery. This application is appropriate for
motorcycles, lawn tractors, ATVs and snowmobiles.
1. To permanently attach to a battery, loosen and remove each nut from the
bolt at the battery terminal.
2. Connect the red (+) POSITIVE connector ring to the (+) POSITIVE battery
terminal.
3. Connect the black (-) NEGATIVE connector ring to the (-) NEGATIVE battery
terminal.
4. Replace and tighten the nuts to secure.
5. Connect the cable to the end of the charger output cord. Take care to keep
the wires and plug away from metal and moving parts.
6. Plug the charger power cord into a grounded electrical wall outlet.

8-Stage Charging Steps:
Step 1: Diagnostics
Checks the battery voltage to make sure battery connections are good and the battery is in a
stable condition before beginning the charge process.
Step 2: Recovery
Initializes the Recovery process, if needed, the charger will perform deeply discharged or
sulfated (desolations) batteries by pulsing small amounts of current.
Step 3: Soft Start
Begins bulk charging process with a gentle (soft) charge.
Step 4-5: Bulk
The bulk charging process continues using both a High Rate or Medium Rate charge so that the
battery will return 80% capacity, and it will indicate by 25%, 50%, 75% charging level.
Step 6: Absorption
It brings the charging level to 90%, the battery charger will deliver small amounts of current to
provide a safe, efficient charge and limit battery gassing.
Step 7: Trickle
Battery is fully charged and ready to use, indicated by the 100% Charge LED illuminate solid
Green. In this step, the battery charger will only deliver enough current to keep the battery in
full charge. If the battery sends signal to the charger that requires more current, then the
battery charger will switch to maintenance stage.
Step 8: Maintenance
The Charger will continuously monitor the battery voltage to determine if a maintenance
charge should be initiated. If the terminal voltage falls below 6.4V (6V) and 12.8V (12V), the
charger will start the maintenance cycle until voltage reaches 7.2V (6V) and 14.4V (12V) and
Page | 10
then it discontinues to the charge cycle. The cycle between trickle and maintenance is repeated
indefinitely to keep the battery at full charge, without overcharging. The battery charger can be
left connected indefinitely.
