BATTERY PACK CHARGING, INSTALLING,
AND REMOVING
Charging procedure
BLACK+DECKER chargers are designed to charge
BLACK+DECKER battery packs in 3.5-4 hours depending
on the pack being charged.
1. Plug the charger into an appropriate outlet before
inserting the battery pack (4).
2. Insert the battery pack into the charger (5).
3. The green LED will flash indicating that the
battery is being charged.
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.
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 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 Charging
mode. This feature ensures maximum battery
life. The light flashes in the pattern indicated
on the label.
Problem power line
When the charger is used with some portable
power sources such generators or sources that
convert DC to AC, the charger may temporarily
suspend operation. The LED flashes in the
pattern indicated on the label. This indicates
that the power source is out of limits.
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.
