OPERATION (continued)
TO CHARGE
A fully discharged battery pack with a temperature between 32°F and 150°F will
charge in about approximately 30 minutes.
• Use battery pack only with the recommended charger.
• Connect the charger to a power supply. Make sure the power supply is
120 volts,
60 Hz, AC only.
• Attach the battery pack to the charger by aligning the raised ribs on the battery
pack with the grooves in the charger, then slide the battery pack onto the
charger (Figure C).
• Do not place the charger and battery pack in an area of extreme heat or cold.
They will work best at normal room temperature.
• Batteries should be charged in an ambient temperature between 50ºF and 100ºF.
• 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 battery pack is fully charged, unplug the charger and remove the battery
pack.
CHARGING A HOT
BATTERY PACK
If the internal temperature of
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 150°F, the charger will
automatically begin fast charge mode.
If the charger does not charge
the battery pack under normal
circumstances, return both the battery
pack and charger to the nearest
authorized service center for testing.
