CHARGING/RECHARGING
Lead-acid batteries require routine maintenance to ensure a full charge and long battery life. All batteries lose energy from self-
discharge over time and more rapidly at higher temperatures. Therefore, batteries need periodic charging to replace energy lost
through self-discharge. When the unit is not in frequent use, manufacturer recommends the battery be recharged at least every 30 days.
IMPORTANT:
If you attempt to use the unit when the unit’s battery charge level is too low, the unit will automatically shut
down. Recharge the unit with all other functions turned off as soon as possible.
WARNING: Never attempt to use the AC and DC charging methods at the same time.
Notes:
This unit is delivered in a partially charged state – you must fully charge it before using it for the first time. Initial AC charge should be for 40 hours.
Recharging battery after each use will prolong battery life; frequent heavy discharges between recharges and/or overcharging will reduce battery life.
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.
Viewing Battery Status
To check the unit’s battery charge level, press the Battery Status Button. The Battery Icon will indicate the battery charge level
as follows:
• If the battery charge level is at full capacity, four solid bars will display.
• If the battery is partially charged, two or three solid bars will display.
• If the battery is nearly empty, one solid bar will display. It is strongly recommended that you recharge the battery at this time.
• If the Battery Icon displays four blank bars, the “+” and “–” icons, and the backlight of the LCD screen comes on, the unit
MUST be charged at this time or the unit’s built-in low voltage protection will activate and shut the unit down in 5 minutes.
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 built-in AC charger before use.
Charging/Recharging Using the Built-In 120 Volt AC Charger and AC Extension Cord
1. Lift the protective cover of the built-in 120 volt AC charger located on the lower left front of the unit (refer to the Features
section to locate). Connect an extension cord to the unit. Plug the other end of the cord into a standard 120-volt AC wall
outlet. When the unit is properly connected to an AC power source, the LCD screen will display the following (the screen
will be backlit):
+
–
+
Area Light
Compressor
Battery
Status
USB
–
The bars on the battery icon represent the capacity level of the unit’s internal battery. After 10 seconds, the backlight will
shut off and the LCD screen will display the following to indicate that the unit is charging:
+
–
+
Area Light
Compressor
Battery
Status
USB
–
The bars on the battery icon will change from empty to solid (bottom to top) repeatedly to indicate the unit is charging.
2. Charge for approximately 40 hours or until the battery icon shows 4 solid bars.
3. When charging is complete, unplug the AC extension cord from the AC outlet and then disconnect it from the unit.
Note:
The unit cannot be overcharged using this method.
The unit will not charge if the inverter power switch is turned on.
12 Volt DC Charging Method
The DC recharging method will NOT recharge the unit as effectively as recharging from 120 volt AC. The 12 volt DC recharging
procedure is recommended only when it is necessary, since frequent use of the 12 volt DC recharging procedure may shorten
the battery system’s life.
Charging the unit from an external 12 volt DC power source requires the use of the 12 Volt DC adapter. This adapter has a male
DC connector at each end.
1. Insert the large grooved tip of the 12 Volt DC Charging Adapter into the vehicle’s 12 volt DC accessory outlet or other
12 volt DC power source.
2. Insert the small silver colored tip into the 12 volt DC accessory outlet on the front panel of the unit (refer to the Features
section to locate).
3. Charge the unit until the battery icon shows full when the battery status button is pressed (with the adapter unplugged
from the unit). DO NOT CHARGE MORE THAN 6 HOURS MAXIMUM USING THIS METHOD.
4. When charging is complete, remove the charging cord and store in a safe place.
Notes:
Some vehicles require that the ignition be switched to the accessory outlet position in order to power the accessory outlet.
Do not leave the unit unattended when charging using the this method.
CAUTION: RISK OF PROPERTY DAMAGE:
•
NEVER connect this unit to a positive grounded vehicle using the 12 Volt DC Charging Adapter.
• The 12 Volt DC Charging Adapter must only be connected to batteries with a nominal output voltage of 12 volts. The unit will
not operate from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
JUMP-STARTER
This unit is equipped with a jump starter power switch that allows energy to flow only when proper connections are made to
battery and frame. 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. Make sure the jump-starter power switch is in the off position.
3. Remove jumper clamps from clamp tabs. Connect the red clamp first, then the black clamp.
4. Procedure for jump-starting a NEGATIVE GROUNDED SYSTEM (negative battery terminal is connected to chassis)
(MOST COMMON)
4a. Connect positive (+) red clamp to vehicle battery’s positive terminal.
4b. Connect negative (–) black clamp to chassis or a solid, non-moving, metal vehicle component or body part. Never clamp
directly to negative battery terminal or moving part. Refer to the automobile owner’s manual.
5. Procedure for jump-starting POSITIVE GROUND SYSTEMS
Note:
In the rare event that the vehicle to be started has a Positive Grounded System (positive battery terminal is connected to chassis), replace steps 4a
and 4b above with steps 5a and 5b, then proceed to step 6.
5a. Connect negative (–) black clamp to vehicle battery’s negative terminal.
5b. Connect positive (+) red clamp to vehicle chassis or a solid, non-moving, metal vehicle component or body part. Never
clamp directly to positive battery terminal or moving part. Refer to the automobile owner’s manual.
6. When the clamps are connected properly, the unit will automatically turn on in jump-starter mode. The backlit LCD screen
will display the following to indicate the unit is ready to jump-start:
+
Area Light
Compressor
Battery
Status
USB
–
+
–
The jump starter icon will flash to indicate the clamps are properly connected.
IMPORTANT:
If the clamps are connected incorrectly with regard to polarity, the reverse polarity connection alarm will sound
continuously and the backlit LCD screen will blink and display the following (the “+” and”–” signs and the alarm icon above
the battery icon flash):
+

Disconnect clamps and reconnect to battery with correct polarity.
7. Turn the Jump-Starter Power Switch to ON.
8. Turn ON the ignition and crank the engine in 5-6 second bursts until engine starts.
9. Turn the Jump-Starter Power Switch back to the OFF position.
