CHARGING LITHIUM-ION BATTERY PACKS
Lithium-ion batteries deliver fade free power for their
entire run time. Tools using DieHard
ion battery packs will not gradually lose power due to
decreasing battery charge. Instead, power from the
battery pack will drop from full to zero once the full charge
has been drained from the battery. Once this happens,
recharging of the battery is required.
It is not necessary to drain the battery pack completely
before recharging.
LED FUNCTIONS OF CHARGER
See Figure 4.
CHARGER LED WILL BE ON TO INDICATE
STATUS OF CHARGER AND BATTERY PACK:
 Red LED on, Green LED off = Power to charger is on.
 Red LED flashing, Green LED off = Battery is being
tested.
 Red LED flashing, Green LED flashing = Battery is
defective.
 Red LED on, Green LED flashing = Battery is charging.
 Red LED off, Green LED on = Battery is fully charged.

TO CHARGE
 Use battery pack only with the recommended charger.
 Connect the charger to the power supply. Make sure
the power supply is normal household voltage,
120 volts, AC only, 60 Hz.
 Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured in the
charger before beginning operation.
 Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
 Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger. See Figure 3.
 Do not place the charger and battery pack in an area
of extreme heat or cold. They will work best at normal
room temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
 The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
 After charging is complete, the green LED will remain
on until the battery pack is removed from the charger
or charger is disconnected from the power supply.
 When batteries become fully charged, unplug the
charger from the power supply and remove the battery
pack.
CHARGING A HOT BATTERY PACK
If the battery pack is above normal temperature range,
the red LED will begin flashing and the green LED will be
off. When the battery pack cools down to approximately
122°F, the charger will automatically begin fast charge
mode.
CHARGING A COOL BATTERY PACK
If the battery pack is below normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery warms to a temperature of more than
32°F, the charger will automatically begin charge mode.
COLD WEATHER OPERATION
The lithium-ion battery pack can be used in temperatures
down to -4°F. Put the battery pack on a tool and use the
tool in a light duty application. After about a minute, the
pack will have warmed up and begin operating normally.
