Charging/Recharging Using The Built-In 120 Volt Ac Charger And Ac Extension Cord (Not Supplied); Charging The Unit Using The 12V Dc Charging Adapter; Important Charging Notes - DeWalt DXAEPS2 Instruction Manual

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.
