Safety instructions
Fire hazard!
Do not place the Rapid Battery Charger...
• where it would be subject to direct sunlight. It could happen
that the Rapid Battery Charger overheats and becomes
irreparably damaged.
• in close adjacency to sources of heat. This includes for example
ovens, fan heaters and similar appliances, as well as the
ventilation openings of electrical devices. The Rapid Battery
Charger could be irreparably damaged.
• in damp environments or in the vicinity of water. Moisture
could permeate into the Rapid Battery Charger resp. into
the power adapter. There would then be the danger of
receiving an electric shock and and/or causing a fire!

• Due to the charging current, only batteries with appropriate
capacities may be charged:
- Ni-MH AA min. 2300mAh / AAA min. 800mAh
- Ni-Cd AA min. 800mAh / AAA min. 300mAh
Should an attempt be made to charge batteries with significantly
lower capacities, the batteries could be destroyed.
• Charge exclusively rapid rechargable batteries of the types
"Ni-Cd“ and "Ni-MH". NEVER recharge batteries of other
types or non-rechargable batteries.
These are not suitable for recharging. Batteries not suitable
for rapid recharging could overheat and explode. This could
irreparably damage the Rapid Battery Charger and the in-
serted batteries. There is also a risk of personal injury!
• Use the Rapid Battery Charger exclusively with the supplied
power adapter resp. vehicle-adapter. Do not use the power
adapter and the vehicle-adapter with appliances other than
the Rapid Battery Charger. Should you do so, the Rapid
Battery Charger, vehicle-adapter, power adapter, batteries
and the other appliance could be irreparably damaged.

 Danger of electrical shock!
DO NOT place the Rapid Battery Charger ...
• in the close vicinity of water, e.g. baths and swimming
pools. Should water permeate into the Universal Battery
Charger, the appliance could be irreparably damaged.
• Remove the power cable from the plug socket before cleaning
the Rapid Battery Charger. You can thus avoid an electric
shock. Should water or moisture permeate into the Rapid
Battery Charger despite observing all precautions, immediately
remove the power cable from the plug socket.
 Injury hazard!
• Always store batteries out of the reach of children! There
is a danger that children could swallow batteries!
Due to the poisonous content of batteries there is a danger
to life!
• When charging batteries never leave the Universal Battery
Charger unsupervised.

• The batteries could become hot during charging. NEVER
touch hot batteries! There is a risk of being burnt! After
charging, first of all remove the power adapter of the
Rapid Battery Charger from the plug socket. Then allow
the batteries to cool down before removing them from the
Rapid Battery Charger.
• The Rapid Battery Charger, the supplied power adapter and
the vehicle-adapter do not contain any user-serviceable
components. Should the housing of these appliances (Rapid
Battery Charger / Power adapter) be opened, the warranty
expires! If repairs are needed, contact one of our service part-
ners in your area. The addresses of our service partners can
be found on the warranty card. This is supplied with the Uni-
versal Battery Charger.
For damage caused by ...
• opening the housings of the Rapid Battery Charger, power
adapter or vehicle-adapter
• attempted repairs made by non-qualified personnel

• improper use of the Rapid Battery Charger, power adapter
and/or the vehicle-adapter, no liability or warranty will be
accepted!
• Leakage of battery acids can occur, especially with old
batteries. You should remove all batteries from the Rapid
Battery Charger if you do not intend to use it for an extended
period. You can thus protect the Rapid Battery Charger
from damage caused by leaking battery acids.

Important:
Never leave the Rapid Battery Charger resp. the batteries in
the vehicle! Under strong sunlight, and with a correspondingly
heated vehicle interior, the Rapid Battery Charger could over-
heat and be irreparably damaged.
Additionally, the batteries could overheat and explode.
There is also a danger of fire!
 Note:
It is possible that the cigar-lighter only functions with a switched-
on vehicle ignition. If you are unsure, consult the vehicle hand-
book.
Caution!
For vehicles in which the cigar lighter resp. on-board power
sockets also function with a switched-off vehicle ignition:
Only use the Rapid Battery Charger with the engine running.
Otherwise, the vehicle batteriy could be completely discharged
by the use of the Rapid Battery Charger!

Troubleshooting
The Rapid Battery Charger displays no functions
With mains power operation:
• Check to see if the low-tension plug on the cable of the power
adapter is correctly inserted into the power adapter con-
nection .
• Check to see if the power socket into which the power
adapter has been inserted is "live".
To do this, connect a different, functioning electrical appliance
to the socket.
With operation over the vehicle-adapter:
• Check to see if the vehicle-adapter is correctly connected
to the Rapid Battery Charger and the cigar-lighter socket.
• It is possible that the cigar-lighter only functions with a
switched-on vehicle ignition. If you are unsure, consult the
vehicle handbook.
