CHARgINg PROCEDURE

BLACK+DECKER chargers are designed to charge BLACK+DECKER battery packs in 5-10
hours depending on the pack being charged: LBXR2020 (5 hrs), LB2X4020 (10 hrs). The
standard charger provided will charge a fully depleted battery in about 10 hours.
1. Plug the charger into an appropriate outlet before inserting the battery pack.
2. Slide the charger onto the battery pack as shown in figure B.
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.
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 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.
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 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 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.
