  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 65  °F – 75  °F 

(18 ° – 24 °C); 

    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.

  6. Foreign materials of a conductive nature such as, but not limited 

to, grinding dust, metal chips, 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 the charger before 

attempting to clean.

  7. Do not freeze or immerse the charger in water or any other liquid.

WARNING:

Shock hazard. Don’t allow any liquid to 

get inside the charger. Electric shock may result. 

WARNING:

Burn hazard. Do not submerge the 

battery pack in any liquid or allow any liquid to enter the battery pack. 

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.

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 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.
