Important Charging Notes
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 40˚F
(4˚C) and 105˚F (41˚C).
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 your tool down until it
is fully discharged before storing your battery pack. After a
long period of 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 chargers or battery packs not sold by Bosch
may void the warranty.
