HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the
charger detects a battery that is hot, it automatically starts a Hot Pack
Delay, suspending charging until the battery has cooled. After the
battery has cooled, the charger automatically switches to the Pack
Charging mode. This feature ensures maximum battery life. The red
light flashes long, then short while in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the
charger is used with some portable power sources such as
generators or sources that convert DC to AC, the charger may
temporarily suspend operation, flashing the red light with two
fast blinks followed by a pause. This indicates the power source
is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light
glowing indefinitely. The charger will keep the battery pack fresh and
fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of
the charger. If the battery pack has not been kept on maintenance
charge, it may need to be recharged before use. A battery pack may
also slowly lose its charge if left in a charger that is not plugged into
an appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery
pack. Such batteries are still usable but should not be expected to
perform as much work. The charger will indicate to replace battery
pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65 °F
and 75 °F (18 °–24 °C). DO NOT charge the battery pack in
an air temperature below +40 °F (+4.5 °C), or above +105 °F
(+40.5 °C). This is important and will prevent serious damage to
the battery pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other
appliance;
b. Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights;
c. Move charger and battery pack to a location where the
surrounding air temperature is approximately 65 °F–75 °F
(18 °– 24 °C);
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into the power
supply, the exposed charging contacts inside the charger can
be shorted by foreign material. Foreign materials of a conductive
nature such as, but not limited to, grinding dust, metal chips, steel
