open the battery pack for any reason. If battery
pack case is cracked or damaged, do not insert
into charger. Do not crush, drop or damage
battery pack. Do not use a battery pack or
charger that has received a sharp blow, been
dropped, run over or damaged in any way (i.e.,
pierced with a nail, hit with a hammer, stepped
on). Damaged battery packs should be returned
to service center for recycling.
not store or carry battery so that metal
objects can contact exposed battery
terminals. For example, do not place battery
in aprons, pockets, tool boxes, product kit
boxes, drawers, etc., with loose nails, screws,
keys, etc. Transporting batteries can
possibly cause fires if the battery
terminals inadvertently come in contact
with conductive materials such as keys,
coins, hand tools and the like. The US
Department of Transportation Hazardous
Material Regulations (HMR) actually prohibit
transporting batteries in commerce or on
airplanes (i.e., packed in suitcases and carry-
on luggage) UNLESS they are properly
protected from short circuits. So when
transporting individual batteries, make sure
that the battery terminals are protected and
well insulated from materials that could
contact them and cause a short circuit.
Lithium-Ion batteries should not
be put in checked baggage.
1. The best storage place is one that is
cool and dry away from direct sunlight and
excess heat or cold.
2. Long storage will not harm the battery
pack or charger.


BLACK+DECKER chargers are designed to
charge BLACK+DECKER battery packs in 3-4
hours depending on the pack being charged.
1. Plug the charger into an appropriate outlet
before inserting the battery pack.
2. Insert the battery pack into the charger.
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.
The charger and battery pack can be left
connected with the green LED glowing
Never attempt to
Fire hazard. Do
indefinitely. The charger will keep the
battery pack fresh and fully charged.


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.
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.
Shock hazard.
