Make sure the extension cord is in good condition before using. Always use  
the proper size extension cords with the tool – that is, proper wire size for  
various lengths of cord and heavy enough to carry the current the tool will  
draw. Use of an undersized cord will cause a drop in line voltage resulting  
in loss of power and overheating. For proper size cords see chart below.

1. The best storage place is one that is cool and dry away from direct  
sunlight and excess heat or cold.  
2. Long-term storage will not harm the battery pack or the charger as  
long as the battery is not depleted..  
wARNING: The charger supplied with this product is intended  
to be plugged in such that it is correctly orientated in a vertical or  
floor mount position.  
Do not expose charger to rain or snow.  
Black and Decker chargers are designed to charge Black and Decker battery  
packs: LCS36 (2 hrs), LCS436 (6 hrs).  
pull by plug rather than cord when disconnecting charger. This  
will reduce risk of damage to electric plug and cord.  
1. Plug the charger into an appropriate outlet before inserting the bat-  
tery pack.  
Make sure that cord is located so that it will not be stepped on,  
tripped over, or otherwise subjected to damage or stress.  
Do not use an extension cord unless it is absolutely necessary.  
Use of improper extension cord could result in risk of fire, electric  
shock, or electrocution.  
2. Insert the battery pack into the charger.  
3. The green LED will flash indicating that the battery is being  
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.  
Do not place any object on top of charger or place the charger on  
a soft surface that might block the ventilation slots and result in  
excessive internal heat. place the charger in a position away from  
any heat source. The charger is ventilated through slots in the top  
and the bottom of the housing.  
Recharge discharged batteries as soon as possible after use or bat-  
tery life may be greatly diminished.  
Do not mount charger on wall or permanently affix charger to any  
surface. The charger is intended to use on a flat, stable surface (i.e.,  
table top, bench top).  
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.  
Do not operate charger with damaged cord or plug — have them  
replaced immediately.  
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.

Do not operate charger if it has received a sharp blow, been  
dropped, or otherwise damaged in any way. Take it to an  
authorized service center.  
Do not disassemble charger; take it to an authorized service center  
when service or repair is required. Incorrect reassembly may result in  
a risk of electric shock, electrocution or fire.  
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 red LED flashes in the pattern  
indicated on the label when the hot / cold pack delay is detected.  
Disconnect the charger from the outlet before attempting any  
cleaning. This will reduce the risk of electric shock. Removing the  
battery pack will not reduce this risk.  
NEVER attempt to connect 2 chargers together.  
The charger is designed to operate on standard household electrical  
power (120 Volts). Do not attempt to use it on any other voltage.  
The charger and battery pack can be left connected with the green LED glow-  
ing indefinitely. The charger will keep the battery pack fresh and fully charged.  
wARNING: For safe operation, read this manual and manuals  
originally supplied with tool before using the charger.  
1. Longest life and best performance can be obtained if the battery  
pack is charged when the air temperature is between 60°F and 80°F  
(16°- 27°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.  
The battery pack is not fully charged out of the carton. Before using the  
battery pack and charger, read the safety instructions below. Then fol-  
low charging procedures outlined.  
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.  
Do not incinerate the battery pack even if it is severely damaged  
or is completely worn out. The battery pack can explode in a fire.  
Toxic fumes and materials are created when battery packs are burned.  
Do not charge or use battery in explosive atmospheres, such as  
in the presence of flammable liquids, gases or dust. Inserting or  
removing the battery from the charger may ignite the dust or fumes.  
If battery contents come into contact with the skin, immediately  
wash area with mild soap and water. If battery liquid gets into the eye,  
rinse water over the open eye for 15 minutes or until irritation ceases. If  
medical attention is needed, the battery electrolyte for Li-ion batteries is  
composed of a mixture of liquid organic carbonates and lithium salts.  
Contents of opened battery cells may cause respiratory irritation. Provide  
fresh air. If symptoms persist, seek medical attention.  
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 60°F - 80°F (16° - 27°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 suf-  
ficient power on jobs which were easily done previously. DO NOT  
CONTINUE to use under these conditions. Follow the charging proce-  
dure. You may also charge a partially used pack whenever you desire  
with no adverse affect on the battery pack.  
wARNING: Burn hazard. Battery liquid may be flammable if  
exposed to spark or flame.  
Charge the battery packs only in black & Decker chargers.  
Do NoT splash or immerse in water or other liquids. This may  
cause premature cell failure.  
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 char-  
ger before attempting to clean.  
Do not store or use the tool and battery pack in locations where the  
temperature may reach or exceed 105°F (40˚C) (such as outside  
sheds or metal buildings in summer).  
wARNING: Never attempt to 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.  
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.  
wARNING: fire hazard. Do 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
