Operation
a) Preparing for charging
•
Place the charger on a fireproof surface and ensure that there are no flammable materials in
the immediate vicinity, especially when charging lithium-ion batteries.
• Plug the power adapter into a standard mains socket. The green LED turns on to indicate that
the charger is supplied with power.
• To interrupt charging or turn the charger off after charging is complete, unplug the power
adapter from the mains. The green LED will turn off after a few seconds, and the four red
charging LEDs will turn on briefly.
b) Charging
• Determine the required charging voltage for the battery that you want to charge (compare the
battery specifications with the information in the "Technical data" section).
• Before inserting the batteries, select the corresponding voltage using the charging voltage
switch. The voltage values are printed next to the charging voltage switch. You can choose
from 1.2 V/DC, 1.5 V/DC, 3.6 V/DC and 4.2 V/DC. The brightness of the green LED increases
when you select a higher charging voltage.
• You can charge 1 to 4 batteries at the same time. If you are charging fewer than 4 batteries,
you can place the batteries in any compartment. The batteries do not need to be inserted at
the same time, as each charging compartment charges the battery independent of the other
compartments.
Warning! When charging more than one battery, only charge batteries of the
same type and charging voltage. You can use the charger to charge batteries with
different capacities, providing that the voltage is the same.
• To charge a battery, place the battery into one of the charging compartments in the correct
polarity. The positive battery pole must be aligned with the positive terminal (and vice versa,
"+" = positive; "–" = negative).
• Important - Do not use force when inserting batteries. Do not use excessive force when
bending the battery contacts. Carefully insert the battery and ensure that the flexible contact
touches the negative pole on the battery.
• Do not insert the battery if it is longer than the maximum compartment length, or if it is too
wide.
• The charging process starts automatically when the battery is inserted correctly and
connected to the contacts at both ends. In addition, the correct charging voltage must be
selected. There is a status LED for each charging compartment, which turns red when the
battery is charging.
• If you want to charge more than one battery, insert additional batteries into the charger until
all compartments are occupied.
• The total charging current of 1200 mA is split between the individual charging compartments,
meaning that the maximum charging current for each compartment is 300 mA when charging
four batteries at the same time.
• If you want to charge batteries with a higher charging current, you will need to insert fewer
batteries. When three batteries are inserted, the maximum charging current per compartment
is 400 mA. 600 mA per compartment is available when two batteries are inserted. When one
battery is inserted, the maximum charging current is 1200 mA.
• If you insert a non-rechargeable battery, the LED of a charging compartment may turn on in
red to indicate the status as charging. Remove the non-rechargeable battery immediately
from the charging compartment in such case in order to avoid hazards such as fire or
explosion.
We recommend discharging Ni-Cd batteries before charging to avoid the so-called
"memory effect". The charger does not have a built-in discharge feature that
discharges batteries before they are charged.
c) Charging time
• Determine the type and capacity of the battery that you want to charge. To calculate the
charging time for a discharged battery, use the following formula:
Charging time = Battery capacity (mAh)
x 1.4
Charging current (mA)
Example: The charging time for a 2500 mAh battery can be calculated as follows:
Charging time =
2500 mAh capacity
x 1.4 = 7 hours
500 mA
d) Trickle charging
• The trickle charging feature is activated automatically when the battery is fully charged. The
status LED next to the corresponding battery compartment will turn off.
• The trickle charging feature prevents the battery from overcharging and replaces the charge
lost through self-discharge. The charger charges each battery to its maximum capacity.
• Remove the charged battery when required, or before disconnecting the charger from the
mains.
e)
Reverse polarity protection
• The charger features reverse polarity protection. The red status LED does not turn on when a
battery is inserted in the incorrect polarity, and the charger will not deliver a charging current.
• Check that the battery is inserted in the correct orientation. If the battery is not inserted
correctly, remove it immediately and reinsert it in the correct position. Charging will then
resume, and the status LED for the corresponding compartment will turn red.
f) Short circuit protection
• The charger switches off immediately in the event of a short circuit. If any batteries are
charging, the corresponding status LEDs will turn off.
• In the event of a short circuit, reset the charger by disconnecting it from the mains. Remove
the faulty batteries, wait for a while and then plug the power adapter back into the mains
socket.
•
To resume charging, follow the steps in the "Charging" section.
Care and cleaning
• Always disconnect the product from the power supply before cleaning it (unplug the power
adapter from the mains socket).
• Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these could
damage the casing or even impair the functioning of the product.
• Use a dry, lint-free cloth to clean the product.
Disposal
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household
waste. At the end of its service life, dispose of the product according to the relevant
statutory regulations.
Remove any inserted batteries and dispose of them separately from the product.
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!
Rechargeable batteries that contain hazardous substances are labelled with this
symbol to indicate that disposal in household waste is forbidden. The designations for
the heavy metals involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (indicated
on rechargeable batteries, e.g. below the trash icon on the left).
Used rechargeable batteries can be returned to collection points in your municipality, our stores
or wherever rechargeable batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.
