Use and Care Manual
HOT/COLD PACK DELAY
DCB101
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.
DCB112
The DCB112 charger has a hot/cold delay feature. When the charger 
detects a battery that is hot, it automatically delays charging until the 
battery has cooled. When the charger detects a battery that is cold, it 
automatically delays charging until the battery has warmed. 
The red light will continue to blink, but a yellow indicator light will 
be illuminated during this operation. Once the battery has cooled, 
the yellow light will turn off and the charger will resume the charging 
procedure.
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 POWER LINE (DCB101)
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.
Wall Mounting
DCB112
These chargers are designed to be wall mountable or to sit upright on 
a table or work surface.
If wall mounting, locate the charger within reach of an electrical outlet. 
Mount the charger securely using drywall screws at least 1" (25.4 mm) 
long, screwed into wood to an optimal depth leaving approximately 
7/32" (5.5 mm) of the screw exposed.
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 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 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 charger and battery pack to a location where the 
surrounding air temperature is approximately 65 ˚F–75 ˚F 
(18–24 ˚C);
