Important Charging Notes
  1. 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 or until the Battery Status Icon shows 4 solid bars.
 2. Recharging the battery after each use will prolong battery life; 
frequent heavy discharges between recharges and/or overcharging 
will reduce battery life.
   3. The battery can be recharged using the built-in 120 Volt AC Charger 
or the 12 Volt DC Adapter.
 4.  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 built-in AC charger before use. 
Charging/Recharging Using the 
Built-In 120 Volt AC Charger and 
AC Extension Cord (not supplied)
 1. Lift the protective cover of the built-in 120 Volt AC Charger 
located on the back of the unit (refer to Fig. 2 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 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, unplug the AC extension cord from 
the AC outlet and then disconnect it from the unit.
Charging the Unit Using the 12V DC 
Charging Adapter
CAUTION – To reduce the 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.
PROCEDURE
  1.  Lift the protective cover of the Built-in 120 Volt AC Charger located 
on the back of the unit (refer to Fig. 2 to locate). Make sure the AC 
extension cord is disconnected from the 120 Volt AC Charger.
