is fully charged.
1. The battery pack accepts only about 80% of its
maximum capacity with its first few charge cycles.
However, after the first few charge cycles, the
battery will charge to full capacity.
2. The charger was designed to fast charge the
battery only when the battery temperature is
between 32˚F (0˚C) and 140˚F (60˚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 140˚F (60˚C), the charger will automatically
begin charging.
3. 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.
4. If you anticipate long periods (i.e. a month or
more) of non-use of your tool, it is best to run

Important Charging Notes
If the red indicator light is "ON", the
battery pack is too hot or cold for fast-
charging. The charger will switch to
trickle charge, until a suitable
temperature is reached, at which time the charger
will switch automatically to fast-charging.
If the red indicator light is "BLINKING",
an acoustical signal will sound for a
period of 2 seconds which indicates the
battery pack cannot accept a charge or
the contacts of the charger or battery pack are
contaminated. Clean the contacts of the charger or
battery pack only as directed in these operating
instructions or those supplied with your tool or
battery pack.
storage, the capacity at first recharge will be lower.
Normal capacity will be restored in two or three
charge/discharge cycles. Remember to unplug
charger during storage period.
5. 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 charger's or battery packs not sold
by Bosch will void the warranty.
