OPERATING INSTRUCTIONS
INTENDED USE
The product serves to charge NiCd-/NiMH battery packs with 5 cells (rated voltage 6 V). The charging
current is max. 1000 mA; it is controlled automatically. The smart Delta-Peak charging deactivation
recognises a charged battery and automatically switches to the „maintenance charge“ mode. The
battery is not overcharged and thus retains its charge condition.
An LED-display indicates the current operating condition at any time. The power source for the charger
is a cigarette lighter adapter with USB connection or a suitable USB plug-in mains adapter (neither is
included in the delivery).
This product complies with the statutory national and European requirements. All company names and
product names are trademarks of their respective owners. All rights reserved.

SAFETY INFORMATION
In case of damage caused by failure to observe these operating instructions, the
guarantee will expire! We do not assume any liability for consequential damage!
We do not assume any liability for damage to property or personal injury caused by
improper use or the failure to observe the safety instructions! The guarantee
expires in these cases.
• The unauthorized conversion and/or modification of the product is prohibited for safety and approval
reasons (CE).
• Chargers and accessories have no place in the hands of children! They are no toys.
• Do not leave Chargers and connected batteries in operation unattended.
• No batteries (zinc-carbon, alkaline, etc.), lead batteries or lithium batteries (Li-Ion, LiPo, etc.) must
be charged; there is a danger of fire and explosion!
• Avoid operation under adverse ambience conditions. They lead to damage to the sensitive
electronics inside the charger and therefore to possible danger for the user’s life. Adverse ambience
conditions are, e.g., too-high ambience temperatures, too-high humidity, moisture, dust and
flammable gases, vapours or solvents, benzines.
• Always observe the charging provisions of the respective battery producer when charging batteries.
• In case of improper handling (too-high charging currents or wrong polarity), the battery may be
overcharged or destroyed. In the worst case, the battery may explode and cause considerable
damage.
• Keep transmitter systems (radio phones, transmitter systems for model construction, etc.) away from
the charger because the ingressing transmitter radiation may cause interference of the charge
operation or destruction of the charger and therefore also the rechargeable battery.
• Never connect your charger to a USB plug-in mains adapter right away after it was taken from a cold
into a warm environment. The condensation that forms might destroy your device under detrimental
conditions. Let the device reach room temperature before connecting it.
If you have reason to believe that the device can no longer be operated safely, disconnect it
immediately and make sure it is not unintentionally operated. It can be assumed that safe operation
is no longer possible if:
- the device shows visible damage
- the device no longer functions
- the device was stored under unfavourable conditions over an extended period of time or
- following considerable stress during transportation.
• At industrial sites, the accident prevention regulations of the association of the industrial workers’
societies for electrical equipment and utilities must be followed.
• In schools, training centres, hobby and self-help workshops, operation of chargers and accessories
must be supervised by responsible trained personnel.
• Do not leave packaging material unattended. It may become a dangerous toy for children.
CONNECTION/COMMISSIONING, CHARGING
Do not use any computer or notebook USB port to connect power to the USB charging
cable because they may be damaged. Use a suitable plug-in mains adapter or a cigarette
lighter adapter with one USB output socket each (output 5 V/DC, at least 2 A).
• Connect the battery to the USB charger.
• Connect the USB charger to the corresponding plug-in mains adapter or a cigarette lighter adapter
with its USB plug.
• After plugging your plug-in mains adapter into a mains socket (e.g. plugging the cigarette lighter
USB adapter into an active cigarette lighter socket), charging commences. this is indicated by the
red charge indicator.
The following LED displays are possible:
The red LED is permanently lit: The charging process is running
The red LED flashes: Defective battery and/or bad contact of the plugs
The green LED is permanently lit: End of charging is reached (maintenance charge)
• The USB charger is applied with a Delta-Peak charge deactivation that automatically terminates the
charging process when the final charging voltage is reached and switches to maintenance charge.
Disconnect the battery from the USB charger first after charging is terminated; then disconnect the
USB charger from its power supply.
¼
The charging time depends on the capacity of the battery to be charged. The higher the battery
capacity, the longer the charging time.
The USB charger has an integrated timer as safety device. If a battery is defective, the USB
charger interrupts charging if no specific voltage curves are detected within a charging time of
two hours. If the battery to be charged is recognised as intact in the first two charging hours
(charging curve OK), the USB charger continues to charge for another four hours. If the battery
is not recognised as „fully charged“ within the total charging time of approx. six hours, the USB
charger deactivates charging as well.
If no LED is lit in spite of a connected battery (charging does not start), either the connection
cable is interrupted or the battery is deep-discharged (voltage below 5 V). Check the charging
configuration with suitable aids (e.g. a meter).
If the battery is deep-discharged, leave it connected to the USB charger for an extended period.
The USB charger uses short charge impulses to test the connected battery; it is charged by this
(during this time, no LED is lit). When the battery voltage has risen to 5 V, the actual charging
process starts.
• To ensure that a battery still works properly after an extended period, batteries should be discharged
/ charged about every month to balance out self-discharge (specifically conventional NiMH-batteries
with their high self-discharge).
• Slight heating up of the rechargeable batteries during charging is normal. Never cover the charger to
prevent damage (by heat accumulation).
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household
waste!
Dispose of the product according to the applicable statutory provisions at the end of its
service life.
b) Batteries and Rechargeable Batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/rechargeable
batteries. Disposing of them in the household waste is prohibited!
Batteries/rechargeable batteries that contain any hazardous substances are labelled with
the adjacent icon to indicate that disposal in domestic waste is forbidden. The descriptions
for the respective heavy metal are: Cd=cadmium, Hg=mercury, Pb=lead (the names are
indicated on the battery/rechargeable battery e.g. below the rubbish bin symbol shown to
the left).
You may return used batteries/rechargeable batteries free of charge at the official collection points of
your community, in our stores, or wherever batteries/rechargeable batteries are sold!
You thus fulfil your statutory obligations and contribute to the protection of the environment.
