CHARGE INDICATORS
This charger is designed to detect certain problems that can arise. Problems are indicated by
the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If
the problem persists, try a different battery pack to determine if the charger is working properly.
If the new pack charges correctly, then the original pack is defective and should be returned
to a service center or other collection site for recycling. If the new battery pack elicits the same
trouble indication as the original, have the charger and the battery pack tested at an authorized
service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it
automatically starts a 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/cold delay
mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack
Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but should not be
expected to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger
will indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
PROBLEM POWER LINE
Some chargers have a Problem Powerline 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.
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 the 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. A cold battery pack will charge at about half the rate of a warm battery pack. The battery
pack will charge at that slower rate throughout the entire charging cycle and will not return
to maximum charge rate even if the battery pack warms.
4. 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 the 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.
5. 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 effect on the battery pack.
6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal
chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away
from charger cavities. Always unplug the charger from the power supply when there is no
battery pack in the cavity. Unplug the charger before attempting to clean.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside the charger. Electric shock
may result.
WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid
to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic
housing of the battery pack breaks or cracks, return to a service center for recycling.
Storage Recommendations
1. The best storage place is one that is cool and dry, away from direct sunlight and excess
heat or cold.
2. For long storage, it is recommended to store a fully charged battery pack in a cool dry
place out of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack
will need to be recharged before use.
