4.1 What you need to know and observe
before charging batteries
4.1.1

General tips

i
Every battery charging process should be preceded
by a battery test using a Bosch battery tester in
order to assess the exact condition of the battery
about to be charged.
¶
The battery charger should be placed on a steady,
horizontal base. The location must be sufficiently
stable. Note the weight of the device and that of the
battery to be charged.
¶
Protect the battery charger against humidity and
moisture.
¶
Do not remove the battery charger's cover. Place the
battery charger in a location where it has at least 15
cm of free air surrounding it for ventilation purposes.
4.1.2 Important notes on charging batteries
¶
Wear protective goggles. Clean any acid splashes
off your skin or clothing immediately, using copious
amounts of water to do so. If necessary you should
visit a doctor.
¶
Batteries should only be charged on well-ventilated
premises.
¶
Avoid any fires, naked flames and sparking when
charging the battery.
¶
Explosive gases are generated during the charging
process.
Pungent gas fumes are an indication of im-
minent danger of explosion!
Proceed as follows:
¶
Do not switch off the battery charger!
Avoid fire, naked flame and any sparking!
¶
Do not disconnect the charger's crocodile
clip-on terminals!
¶
The room is to be well ventilated immedi-
ately!
¶
Set the rotary control to its furthermost
left-hand setting (lowest battery charge
current)!
¶
After ventilating the room switch the power
switch on the charger to „0" (OFF)!
¶
Have the battery checked by a Bosch Ser-
vice Point.

¶
When charging batteries in the vehicle or where
performing a start-assist measure, follow the vehicle
manufacturer's instructions.
¶
Only tested batteries should be used in parallel to
charge a battery.
¶
Do not charge absolutely maintenance-free batteries
together with standard batteries (maintenance free
as under DIN).
¶
Do not attempt to charge a non-chargeable battery.
¶
Switch off all consumers in the vehicle when charg-
ing exhaustive discharge batteries and when per-
forming a start-assist measure.
¶
The battery nominal voltage and the selected battery
charging current must match.
¶
The mains supply cable and the battery charger
cables with the crocodile clips must be in perfect
condition.
!
The cable lengths and the cable cross section of the
charger's cable must not be altered in any way. The
original battery charger cable must always be con-
nected.
¶
Before connecting the battery charger to the mains
supply, switch the mains switch on the battery char-
ger to „0" (OFF).
¶
Unscrew the cell plugs on standard batteries before
starting the charging process.
¶
When charging vehicle batteries in the installed condi-
tion, connect the black terminal clip (‒) to the body,
away from the battery and fuel pipe line.
¶
Switch the battery charger off before connecting/dis-
connecting the charger's crocodile clip-on terminals.
¶
Never disconnect them while a charging process is
underway.
¶
The battery must not be disconnected from the
vehicle's electrical system for as long as the charging
process is underway.
¶
Never short circuit the charger's crocodile clip-on
terminals.
