The lithium ion battery is protected against
deep discharging by the “Electronic Cell
Protection (ECP)”. When the battery is empty,
the tool is switched off by means of a
protective circuit.
The battery is supplied partially charged.
Completely charge the battery before using
your cordless screwdriver for the first time.
The lithium ion battery can be charged at any
time, without reducing its service life.
Interrupting the charging procedure does not
damage the battery.
Plug charger cord into your standard power
outlet, then insert battery pack into charger
(Fig. 4).
CHARGING BATTERY PACK (Model BC430)
If the indicator lights are “OFF”, the charger
is not receiving power from power supply
outlet.
If the green indicator light is
“ON”, the charger is plugged in
but the battery pack is not
inserted, or the battery pack is fully charged
and is being trickle charged.
If the green indicator light is
“BLINKING”, the battery pack is
being fast-charged. Fast-
charging will automatically stop when the
battery pack is fully charged.
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”, 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.

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.
