Charge Indicators 

This charger is designed to detect certain problems that can arise. Problems are indicated 

by the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the 

charger. If the problem persists, try a different battery pack to determine if the charger 

is working properly. If the new pack charges correctly, then the original pack is defective 

and should be returned to a service center or other collection site for recycling. If the new 

battery pack elicits the same trouble indication as the original, have the charger and the 

battery pack tested at an authorized service center. 

HOT/COLD DELAY

This charger has a hot/cold delay feature: when the charger detects a battery that is 

hot, it automatically starts a delay, suspending charging until the battery has cooled. 

After the battery has cooled, the charger automatically switches to the pack charging 

mode. This feature ensures maximum battery life. The red light flashes long, then 

short while in the hot/cold delay mode. 

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge indicator showing 

Pack Charged.

WEAK BATTERY PACKS:

 Weak batteries will continue to function but should not be 

expected to perform as much work. 

FAULTY BATTERY PACKS:

 This charger will not charge a faulty battery pack. The 

charger will indicate faulty battery pack by refusing to light or by displaying problem pack 

or charger. 

NOTE: 

This could also mean a problem with a charger.

PROBLEM POWERLINE

Some chargers have a problem powerline indicator. When the charger is used with 

some portable power sources such as generators or sources that convert DC to AC, the 

charger may temporarily suspend operation, flashing the red light with two fast blinks 

followed by a pause. This indicates the power source is out of limits.

Important Charging Notes

  1.  Longest life and best performance can be obtained if the battery pack is charged 

when the air temperature is between 18 ° – 24 °C (65 °F and 75 °F). DO NOT 

charge the battery pack in an air temperature below +4 °C (+40 °F), or above 

+40 °C (+105 °F). This is important and will prevent serious damage to the 

battery pack.

  2.  The charger and battery pack may become warm to the 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.  A cold battery pack will charge at about half the rate of a warm battery pack. The 

battery pack will charge at that slower rate throughout the entire charging cycle 

and will not return to maximum charge rate even if the battery pack warms.

  4.  If the battery pack does not charge properly:
    a.  Check operation of 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 the charger and battery pack to a location where the surrounding air 

temperature is approximately 18 ° – 24 °C (65 °F and 75 °F); 

    d.  If charging problems persist, take the tool, battery pack and charger to your 

local service center.

  5.  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 effect on the battery pack.
