Craftsman 320.61199 Battery Protection, Cold Weather Operation, When to Charge the Battery Pack

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 situations involving extremely high torque, binding, and stalling. 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) - 122°F (50°C).

The LED worklight light will begin flash slowly if the battery circuitry detects a momentary overload.

NOTE: 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.)

NOTE: A significantly reduced run time after fully charging the battery pack indi- cates 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 Fig. 2 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 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. Charge the battery pack as needed.
