2. Recharging the battery after each use will prolong battery life;
frequent heavy discharges between recharges and/or overcharging
will reduce battery life.
3. Make sure all other unit functions are turned off during recharging,
as this can slow the recharging process.
CAUTION – Risk of property damage: Failure to keep the battery
charged will cause permanent damage and result in poor jump starting
performance.
IMPORTANT: If you know the unit is discharged, but the battery icon
displays four solid bars as if the unit is fully charged when connected to
a charging power source, this may be due to the internal battery having
high impedance. The manufacturer suggests leaving the unit charging
for a period of 40 hours using the supplied AC charger before use.
Charging/Recharging Using the
Supplied Charging Adapter
1. Lift the protective cover of 12V DC Charging Port located on the
back of the unit (refer to Fig. 2 to locate). Insert the barrel connector
of the AC charging adapter into the DC charging port. Insert the
plug end into a (powered) standard North American 120 volt 60Hz
outlet. When the unit is properly connected to an AC power source,
the LCD screen will display the following:
The bars on the Battery Status Icon represent the charge level of
the unit’s internal battery. The bars on the Battery Status Icon will
change from empty to solid (bottom to top) repeatedly to indicate
the unit is charging. The backlight will turn on for 10 seconds (only).
2. Charge for approximately 40 hours or until the Battery Status Icon
shows 4 solid bars.
3. When charging is complete, disconnect the AC charging adapter –
first unplug the adapter from the AC power source, then disconnect
the barrel connector from the unit.
Jump-Starter
A. For negative-grounded systems (most common), connect the
positive (red) clamp to the positive ungrounded battery post
and the negative (black) clamp to the vehicle chassis or engine
block away from the battery. Do not connect the clamp to the
carburetor, fuel lines or sheet-metal body parts. Connect to a
heavy gage metal part of the frame or engine block.
B. For positive-grounded systems, connect the negative (black)
clamp to the negative ungrounded battery post and the positive
(red) clamp to the vehicle chassis or engine block away from the
battery. Do not connect the clamp to the carburetor, fuel lines or
sheet-metal body parts. Connect to a heavy gage metal part of
the frame or engine block.
IMPORTANT: . All features
must be turned off with the
exception of the area light
when jump-starting. The unit
is intended to be used only in
the upright position. The unit
must be kept upright during
use. See the illustration
to the right for correct
orientation.
WARNING – To reduce the risk of serious injury or property
damage:
• Follow all safety instructions found in the “Specific Safety Instructions
for Jump Starters” section of this instruction manual.
• If the clamps are connected incorrectly with regard to polarity, the unit
will sound a continuous alarm until the clamps are disconnected. The
backlit LCD Screen will display the Battery Status Icon, the Battery
Voltage Indicator and the Clamp Icons. The “+” and”–” signs above
the Clamp Icons, the Arrow Icons and the Alarm Icon will flash. The
backlit LCD screen will display the following:
Disconnect the clamps and reconnect to battery with correct polarity.
• Never touch red and black clamps together. This can cause
dangerous sparks, power arcing, and/or explosion.
If the red and black clamps touch each other, the unit will sound a
continuous two-second alarm every ten seconds until the clamps are
separated. The backlit LCD screen will display the following:
The Battery Status Icon and Battery Voltage Indicator light solid.
The Alarm Icon, Clamp Icons and the “+” and”–” signs will flash.
Immediately separate the clamps and do not allow them to touch
again.
• If the unit is overheated during the jump starting process, the thermal
protection will activate and the backlit LCD screen will display the
following:
The Battery Status Icon and Battery Voltage Indicator light solid. The
alarm icon and Jump Starter Icon will flash. Allow the unit to cool for
10-30 minutes before use.
• Always disconnect the negative (black) jumper cable first, followed by
the positive (red) jumper cable, except for positive grounded systems.
PROCEDURE
Take the following steps, observing all cautions and warnings in the
“Important Safety Instructions” section at the front of this manual.
1. Turn off vehicle ignition and all accessories (radio, A/C, lights,
connected cell phone chargers, etc.). Place vehicle in “park” and
set the emergency brake.
2. Remove jumper clamps from clamp tabs. Connect the red clamp
first, then the black clamp.
3. Procedure for jump-starting a NEGATIVE GROUNDED
SYSTEM (negative battery terminal is connected to chassis)
(MOST COMMON)
3a. Connect positive (+) red clamp to vehicle battery’s positive
terminal.
3b. Connect negative (–) black clamp to chassis or a solid, non-
moving, metal vehicle component or body part. Never clamp
