Charge Indicators

HOT/COLD PACK DELAY
The DCB107 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 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 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 +104 °F
(+40 °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.
