Bosch Power Tools 1 609 92A 18P | (29.6.15)
Charging Procedure
The charging process begins as soon as the 12 V plug 6is
plugged into an energised 12 V socket, the specified input
voltage is present (the vehicle engine has been started) and
the inductive battery 1or the power tool with battery 1(with
base of the battery) is placed onto the charging platform 5.
Thechargingprocessonlybegins whenthebatterycapacityis
less than 85 – 90 %. This prolongs the life of the battery.
Due to the intelligent charging method, the charging condi-
tionofthe battery is automatically detectedandthebatteryis
charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Meaning of the Indication Elements
Continuous Light Standby Indicator (green) 2
The continuous light of the green standby indica-
tor 2shows that input voltage is present and the
charger is ready to use.
Flashing Charge Status Indicator 3
The fast charging process is indicated by
the flashing of the respective greenLED of
the charge status indicator 3. When the re-
spectiveshareofthebatteryischarged,the
green flashing light changes to a green continuous light.
The battery can be removed at any time and used. When all
five LEDs indicate a green continuous light, the battery is fully
charged.
Continuous Light Error Indicator (red) 4
The continuous light of the red error indicator 4
shows that the temperature of the battery or
charger is outside of the permitted charging tem-
perature range, see section “Technical Data”. As
soon as the permitted temperature range is reached, the
charger automatically switches to fast charging.
Flashing Error Indicator (red) 4
The flashing light of the red error indicator 4sig-
nals a different fault of the charger, see section
“Troubleshooting – Causes and Corrective Mea-
sures”.
Working Advice
The charger is combined with a voltage transformer 9which
converts the 12 V on-board voltage into a 290 V voltage.
When doing so, the voltage transformer 9monitors the bat-
teryvoltage in the vehicle. It isdesigned to switch the charger
on only when the engine is running or at an on-board voltage
> 13 V (+/- 0.3 V). If the engine is switched off or at an on-
board voltage < 13 V (+/- 0.3 V), the charger will switch itself
off automatically after a follow-up time of 3 minutes.
As the charger also draws power from the starter battery
when no battery is being charged (idling), it should bediscon-
nected from the power supply when not being used for pro-
longed periods of time.
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaningful
and does not indicate a technical defect of the battery charg-
er.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Troubleshooting – Causes and Corrective
Measures
Maintenance and Service
If the battery charger should fail despite the care taken in
manufacturing and testing procedures, repair should be car-
ried out by an authorised after-sales service agent for Bosch
power tools.
In all correspondence and spare parts orders, please always
include the 10-digit article number given on the type plate of
the charging unit or voltage transformer.

Cause Corrective Measure
Red error indicator 4 flashes
No charging procedure possible
The battery is not positioned
(correctly) Position the battery centrally
with the battery base on the
charging platform 5
Detection of foreign object
An object other than / in addi-
tion to the battery is on the
charging platform 5
Remove object
Wrong battery positioned Position a compatible battery
Battery pack defective Replace the battery
Standby indicator (green) 2 does not illuminate
On-board voltage too low Start engine (charge starter
battery).
12 V plug of the charger 6is
not plugged in (correctly) Plug the 12 V plug 6into the
socket (completely).
Cordsocket11andcordplug
10 not (correctly) connected Connect cord socket 11 and
cord plug 10.
Socket outlet, mains cable or
battery charger defective Check on-board voltage,

Voltage transformer 9is too
warm Wait until the voltage trans-
former has cooled down.
