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 light 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. Put the battery pack on a 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 convenient for you and your job.
"Top off" the battery pack charge by charging it for a time before starting a big
job or a 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.
To signal the end of charge, power to the tool will drop quickly, or the FuelGauge
feature on tools so equipped will indicate diminishing and depleted battery
power. Charge the battery pack as needed.
FueIGauge (Fig.14}
This tool is equipped with a FuelGauge which indicates the battery-pack charge level.
The green LED on the FuelGauge indicates that the battery is fully charged.
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.
