Battery Protection; Cold Weather Operation - Craftsman NEXTEC 320.30565 Operator's Manual

LOW-BATTERY CAPACITY INDICATOR
• If the FuelGauge shines red when the trigger switch on the drill/driver is
depressed it means that the battery pack power has run out and the battery
pack should be recharged.
Unlike other battery-pack types, Lithium-Ion battery packs deliver fade-free
power for their entire run time. The tool will not experience a slow, gradual
loss of power as you work. To signal that the battery pack is at the end of its
run time and needs to be charged, the power to the tool will drop quickly.
NOTICE: The work light may also flash due to an overload or high temperature
(see BATTERY PROTECTION).
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 when it returns to approximately 122 ° F (50° C).
The LED worklight light will begin flash slowly if the battery circuitry detects a
momentary overload.
NOTICE: The battery can automatically reset. If the LED continues to flash rapidly,
it is indicating that the charge is substantially diminished. Place the battery into the
charger for charging. (See BATTERY CAPACITY INDICATOR, above.)
NOTICE: 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"
that reduces total charge when recharged after 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 long period of use.
