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,
