BATTERY PROTECTION
The battery circuitry protects the battery pack from extreme temperature,
over-discharge, and over-charge. To protect the battery from damage and
prolong its life, the battery pack circuitry will turn off the battery pack if it
becomes overloaded or if the temperature becomes too high during use. This
may happen in extremely high torque, binding, and stalling situations. This
intelligent system will shut down your battery pack if its operating temperature
exceeds 176°F (80°C) and will begin normal operation when it returns to 32°F
(0°C) - 104°F (40°C).
The LED worklight will begin to flash slowly if the battery circuitry detects a
momentary overload.
NOTE: A significantly reduced run time after fully charging the battery pack
indicates that the battery is near the end of its usable life and must be replaced.
COLD WEATHER OPERATION
This Lithium-Ion battery pack will provide optimal performance in temperatures
between 32°F (0°C) and 104°F (40°C). When the battery pack is very cold, it may
"pulse" for the first minute of use to warm itself. Install the battery pack in the
tool and use the tool in a light application; after about a minute, the battery pack
will have warmed itself and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
It is not necessary to run down the battery pack charge before recharging. The
Lithium-Ion battery can be charged at any time and will not develop a "memory"
when charged after only a partial discharge.
Remove the battery pack from the tool when it is convenient for you and your
job. "Top off" the battery pack charge by charging it for a time before starting a
big job or long period of use.
Due to Lithium-Ion fade-free properties, the only time it is necessary to charge
the Lithium-Ion battery pack is when the pack has reached the end of its charge.
The orange LED on the FuelGauge indicates that the battery has used
approximately one half of its charge.
The red LED on the FuelGauge indicates the battery pack is depleted and needs
to be charged.
Charge the battery pack as needed.
HOW TO CHARGE THE BATTERY PACK (Fig. 2)
NOTE: This Lithium-Ion battery pack is shipped partially charged. Before using it
the first time, fully charge the battery pack.
A fully discharged battery pack will charge in about 30 minutes in a surrounding
temperature between 32°F (0°C) and 104°F (40°C).

battery pack with the
correct charger.
Connect the charger to a
power supply.
Align the raised ribs of the
battery pack with the slot in
the charger.

The green lights will flash while the battery pack is charging. After charging
is complete, the green LED on the charger will be on. The flickering red light
indicates a defective battery or a bad connection between the battery and
the charger.
The battery pack will fully charge if left on the charger, but it will not
overcharge.
NOTE: For your convenience, the charger can operate with most generators and
inverters rated at 300 watts or higher.
