CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may
become hot. A hot battery pack may be placed directly
onto the charger port but charging will not begin until the
battery temperature cools to within acceptable temperature
range. When a hot battery pack is placed on the charger,
the red LED will begin flashing and the green LED will be off.
When the battery pack cools, the charger will automatically
begin charging.
