Notes on rechargeable batteries
• Keep rechargeable batteries out of the reach of children.
• Do not leave batteries lying around, as they constitute a choking hazard for chil-
dren and pets. Seek immediate medical advice if a battery is swallowed.
• Rechargeable batteries must never be short-circuited, dismantled or thrown into
re. This may cause an explosion!
• When charging is complete, be sure to remove the rechargeable batteries from
the charger.
• When handling leaking or damaged batteries, always use suitable protective
gloves to avoid burning your skin.
• Liquids leaking from batteries are chemically very aggressive. Objects or surfaces
coming into contact with these liquids could be severely damaged. Always store
batteries in a suitable location that is not prone to damage.
• Do not attempt to recharge disposable, non-rechargeable batteries. This may
cause a re or explosion! Only recharge batteries that are marked as recharge-
able.
• Always observe the correct polarity (positive/+ and negative/-) when inserting bat-
teries into the charger.
• The charger is only suitable for 9 V block batteries with NiMH, NiCd, Li-ion and
LiFePo4 battery technology.
• It is normal for the rechargeable batteries to become warm during charging. Allow
the rechargeable batteries to cool down to room temperature before using them.
Connections and product overview
1 Micro USB socket for voltage/
power supply of the charger
2 LED for charging slot 1
3 Charging slot 1
4 LED for charging slot 2
5 Charging slot 2
Operation
a) Connection
Use the supplied USB cable to connect a USB power adapter to the micro USB socket of the
charger. The LEDs on the charger light up red briey and then green. The charger is now ready
to work.
Do not connect the USB cable to the USB port of a computer or USB hub as the
charging power will not be sufcient. There is also a risk that the USB port will be
damaged.
b) LED indicator light
A LED of each charge slot shows the current status of the corresponding charge slot:
LED Function
LED lights up green Standby/no rechargeable battery inserted/charging is completed
LED lights up red Battery charging
Flashing red LED Error: Rechargeable battery defective/deeply discharged, etc.;
input current too low (<0.5 A)
c) Charging 9 V block batteries
• The two charging slots are independent of each other. You can easily charge two different
9 V block batteries.
If the input current is too low (<1 A), you can only use charging channel 1 for charg-
ing.
• Insert the 9 V block battery to be charged in charging slot 1 or 2, observing the correct
polarity (observe plus/+ and minus/-, see imprint on the rechargeable batteries and in the
charging slots).
A lug on the plus contact in each of the two charge slots prevents the wrong insertion
of a rechargeable battery. Therefore, do not insert the rechargeable battery in the
charging slot forcefully!
• The rechargeable batteries are checked briey and the charging process starts automati-
cally.
• When charging is complete, remove the rechargeable batteries from the charger.
For safety reasons, charging stops automatically after approx. 8 hours, even if the
rechargeable batteries are not yet fully charged.
Care and cleaning
• Disconnect the product from the voltage/power supply before each cleaning, remove any
inserted rechargeable batteries from the charger.
• Use a dry, lint-free cloth to clean the product.
Never use aggressive detergents, rubbing alcohol or other chemical solutions, as
these may damage the casing or cause the product to malfunction.
Disposal
a) Product
Electronic devices are recyclable waste and must not be placed in household waste.
At the end of its service life, dispose of the product according to the relevant statu-
tory regulations.
b) Rechargeable batteries
As the end user, you are required by law (Battery Ordinance) to return all used rechargeable
batteries; they must not be disposed of in household waste!
Contaminated rechargeable batteries are labeled with this symbol to indicate that
disposal in the domestic waste is forbidden. The abbreviations for heavy metals in
batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead (indicated on the battery,
e.g. below the trash icon on the left).
Used batteries can be returned to local collection points, our stores or battery retailers.
You thus full your statutory obligations and contribute to environmental protection.
