HOT/COLD PACK DELAY
The DCB107-B5 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.
XR Li-Ion tools are designed with an Electronic
Protection System that will protect the battery
against overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the
Li-Ion battery on the charger until it is fully charged.
