5.1 BATTERY CHARGER
The mains supply must comply with the specifi cati-
ons on the rating plate (Fig. 5).
The battery charger is suitable only for charging
batteries from the Bosch range of tools (NiCd/
NiMH) with voltages between 7.2 V and 14.4 V.
5.2 FIRST BATTERY CHARGE
NOTE:
Please observe the following points in order to
ensure optimum battery life:
– Connect battery charger (177) to mains supply.
– Insert battery (176) into battery charger slot.
For the fi rst charge, leave the battery in the
charger for at least fi ve hours, regardless of the
battery indicator
(the charging time for all subse-
quent charges is about 60 minutes).
For all subsequent charges, only recharge the
battery when the LED indicator on the tool indi-
cates battery empty (see Chapter 6.3). Avoid
charging when the battery is not yet dischar-
ged. This will ensure optimum battery capacity
and life.
Maximum battery output will be reached after four
or fi ve charging/discharging cycles.
5.3 CHARGING THE BATTERY
The charging process and error functions are indi-
cated by a green light (see chapter 4.4).
The charging time is approximately 60 minutes.
The maximum charging current fl ows when the
tem-perature of the battery is between 15–40°C.
Avoid charging the battery at temperatures below
0°C and above 40°C.
NOTE:
If the battery is not to be used for a longer
period (several days), it should be removed
from the tool and charged/stored in the battery
charger.
The intelligent charger with fuzzy control charges
the battery with the optimum rapid charging current,
depending on temperature and capacity. If fully
charged, a preserving charge will prevent selfdi-
scharge and thus guarantee a long battery life.
