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 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 Charging mode. This feature ensures maximum battery life. The red LED
flashes in the pattern indicated on the label.

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.
