4. Recharge discharged batteries as soon as possible after use or battery life
may be greatly diminished.
CHARGE INDICATORS
Replace Pack:
These chargers are designed to detect certain problems that can arise with battery packs
which would be indicated by the red light flashing at a fast rate. If this occurs, re-insert
battery pack. If problem persists, try a different battery pack to determine if the charger is
OK. If the new pack charges correctly, then the original pack is defective and should be
returned to a service center for recycling. If the new battery pack gives the same trouble
indication as the original, have charger tested at an authorized service center.
Note: It may take as long as fifteen minutes for the charger to determine that the pack is
defective.
If the battery pack is too hot or too cold, the LED will alternately blink fast and slow, one
flash at each speed and repeat.
DAISY CHAIN (FIGURE C)
Single and dual port chargers can be electrically connected in any order up to a
maximum of 4 chargers. Each charger has a power-in cord (which plugs into the
electrical outlet) and a power-out cord (which plugs into the next charger).
To connect chargers in a daisy chain:
1.) Plug the power-in cord into an electrical outlet.
2.) Remove the power-in cord from the next charger and plug in the power-out cord
from the charger that is now plugged into the outlet.
3.) Repeat this process for the remaining chargers.
Chargers that are daisy chained together operate independently as though each one
was plugged into a sperate outlet therefore a battery can be removed from anywhere
along the daisy chain without affecting the other chargers.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected indefinitely with the LED illuminated.
You may see the LED return to flashing (charging) state, as the charger will occasionally
“top off “ the battery charge.
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°C - 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.
Note: The charger will not charge a battery pack if the pack temperature is
below approximately 32°F (0°C) or above 122°F (50°C). The battery pack
should be left in the charger and the charger will begin to charge automatically
when the cell temperature warms up or cools down.
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.
