IMPORTANT CHARGING NOTES
1.The charger was designed to fast charge the battery only when the battery temperature is between 32˚F (0˚C) and 113˚F (45˚C). If the battery pack is too hot or too cold, the charger will not fast charge the battery. (This may happen if the battery pack is hot from heavy use). When the battery temperature returns to between 32˚F (0˚C) and 113˚F (45˚C), the charger will automatically begin charging.
2.A substantial drop in operating time per charge may mean that the battery pack is nearing the end of its life and should be replaced.
3.Remember to unplug charger during storage period.
4.If battery does not charge properly:
a.Check for voltage at outlet by plugging in some other electrical device.
b.Check to see if outlet is connected to a light switch which turns power “off” when lights are turned off.
c.Check battery pack terminals for dirt. Clean with cotton swab and alcohol if necessary.
d.If you still do not get proper charging, take or send tool, battery pack and charger to your local Bosch Service Center. See “Tools, Electric” in the Yellow Pages for names and addresses.
Note: Use of chargers or battery packs not sold by Bosch will void the warranty.

The battery pack may be used even though the light may still be blinking. The light may require more time to stop blinking depending on temperature.
The purpose of the green light is to indicate that the battery pack is
