4. The completion of charge is indicated by the green LED remaining on continuously.
The pack is fully charged and may be used at this time or left on the charger.
Recharge discharged batteries as soon as possible after use or battery life may
be greatly diminished. For longest battery life, do not discharge batteries fully. It is
recommended that the batteries be recharged after each use.
FLASh ChARGE CYCLE
When the flash button is pushed the charger “boosts” the charge current for 10 minutes
and starts blinking the blue LED while the green LED blinks.
After 10 minutes the blue LED will stay on and the green LED will continue blinking until
the battery pack is fully charged. Once the charge cycle is complete, the green LED and
blue LED will remain on continuously.
ChARGER DIAGNOSTICS
This charger is designed to detect certain problems that can arise with the battery packs
or the power source. Problems are indicated by one LED flashing in different patterns.
BAD BATTERY
The charger can detect a weak or damaged battery. The red LED flashes in the
pattern indicated on the label. If you see this bad battery blink pattern, do not continue
to charge the battery. Return it to a service center or a collection site for recycling.
hOT/COLD PACk DELAY
When the charger detects a battery that is excessively hot or excessively cold, it
automatically starts a Hot/Cold Pack Delay, suspending charging until the battery
has normalized. After this happens, the charger automatically switches to the Pack Charg-
ing mode. This feature ensures maximum battery life. The red LED flashes in the pattern
indicated on the label.
LEAvING ThE BATTERY IN ThE ChARGER
The charger and battery pack can be left connected with the green LED glowing
indefinitely. The charger will keep the battery pack fresh and fully charged.
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 current at 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. Foreign materials of a conductive nature such as, but not limited to, 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 charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING:
Shock hazard. Do not allow any liquid to get inside charger. 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.
