3. Intended use
The compact charger is intended for charging lead-acid, calcium and lithium batteries with a 12 V terminal voltage and a capacity of 14 Ah to 225 Ah. Possible battery types are lead-fleece (AGM) or gel batteries. It can also charge batteries installed in vehicles. The intelligent charger recognises deeply discharged batteries and facilitates reactivation by applying increased charging voltage. It can also break down sulphate deposits in old or poorly maintained batteries. This extends battery service life and improves performance. A trickle charging function keeps the battery voltage at an optimal level. The charger is operated with an operating button.. Operation and status are displayed by means of LED indicators. The charger is protected against overload, short circuit, overheating and incorrect polarity. The terminals are live above 0.6 - 0.8 V only when a connected battery is recognised. This prevents sparks from occurring when the terminals make contact unintentionally. The connection is made with colour-coded terminals (positive +, negative -) for universal contact, or eyelets for permanent contact. The connection for charging and for the supply voltage may also be provided via the cigarette lighter socket in a vehicle and a vehicle plug. The charging connections can be exchanged with a reverse-polarity protection socket system. No primary batteries (zinc-carbon, alkaline, etc.) or batteries other than the types specified (see ‘Technical Data’) may be connected or charged.
The charger may only be connected to common household AC voltage and may only be used in well ventilated indoor areas. Power is supplied by mains voltage of 220 - 240 V/AC.
This product is intended for indoor use only. Do not use it outdoors. Contact with moisture (e.g. in a bathroom) must be avoided under all circumstances.
For safety and approval purposes, do not rebuild and/or modify this product. Using the product for purposes other than those described above may damage the product. In addition, improper use can cause hazards such as a short circuit, fire or electric shock. Read the operating instructions carefully and store them in a safe place.

You can connect the charger to the cigarette lighter socket in your vehicle with the aid of the supplied adapter cable with vehicle plug (17). Switch off the ignition and other consumers before plugging in. Note and observe the information in the operating instructions of the vehicle. The vehicle plug has its negative terminal on the outside and positive terminal on the tip on the inside. Charging via this adapter works only if the cigarette lighter is connected to permanent positive. It must, therefore, work even when the ignition is off.
•When releasing the adapter cable connection from the charging cable, first press lightly on the locking mechanism then pull the cable ends apart. Never pull on the cables with force before opening the locking mechanism.
•Insert the mains plug (13) of the charger into a mains socket (220 - 240 V/AC, 50/60 Hz). The charger is initialised and checks each individual charging function. The indicator LEDs light up briefly.
This charger has an automatic memory function, i.e. it automatically returns to the last selected charging mode when it is connected to the AC power supply of the grid.
•Now select a charging function with the MODE button (1). Press the button until the LED or LEDs of the desired function light up. For a description of the individual charging modes, see ‘b) Charging modes and functions’ below.
Only connect the adapter cable to the battery to be charged. Never connect directly to other devices.
•Now connect the charger to the battery. Please observe the correct polarity. Connect the battery with the correct polarity. The red adapter cable to the positive terminal, the black adapter cable to the negative terminal. Disconnect the cable of the red and black terminals on the battery terminals. Screw the eyelet connection firmly onto the terminal contacts (red and black terminal and eyelet connection, black = negative terminal, red = positive terminal).
The cigarette lighter adapter simply plugs into the cigarette lighter socket of the vehicle.
If you are charging installed batteries with a connected on-board electrical system, first connect the positive terminal, and then clip the black terminal to earth (body), at some distance from the battery and the fuel pipe. Check the firm connection of the terminals.
•Disconnect all consumers from the battery If the battery is installed in a vehicle, switch off the ignition and other consumers. You can switch it on again when you have ensured that everything is OK and that the total power consumption of the consumers does not exceed 7 A.
Follow the instructions and safety information of the vehicle for information on charging the vehicle battery.
Modern vehicles are equipped with sensitive electronic components and sensors, all of which could be damaged if you fail to proceed with caution.
•If the polarity is incorrect, the Reversed LED (11) lights up. Check the polarity and connect the terminals with the correct polarity.
•If the charging loop is short-circuited, the Short Circuit LED (10) lights up and flashes.
•The charger detects faulty batteries automatically. In that case, the selected charging program is not started. The Defective LED indicator (12) lights up. Have the battery checked by a professional or obtain a replacement.
•Disconnect the battery and the charger from the power supply at the end of the charging process. Remove the mains plug (13) from the socket, then remove the black followed by the red terminal from the battery.

Power supply function (max. 7 A)
•The charger can also be used as a power supply unit (up to max. 7 A power consumption). There is no manual switching option for selecting the power supply function. This power supply function is triggered automatically by the charger when external consumers consume current via the battery. The maximum available current is 7 A.
•Ensure that consumers do not draw current while the charger is not yet connected to the battery. Do not connect any products that require a continuous/stabilised operating voltage of 12 V (e.g. a computer). Ensure that no consumers are connected to the charger before the mode can be automatically activated.
12
Recovery function
•This function is intended for regenerating deeply discharged batteries. It cannot be selected directly. If a deeply discharged battery is connected to the charger, recovery function starts first.Alow charging current is used to bring the deeply discharged battery back to normal battery voltage. Once the battery reaches its normal voltage, the charger proceeds with normal charging.
c) Charging time
•The time it takes to reach the charging end voltage depends on several parameters, such as e.g. -- The capacity (Ah) (the greater the capacity, the longer the charging time)
-- The type of battery
-- The charge status of the battery (full, half-full or empty)
-- The ambient temperature (this should ideally be 20 - 25 °C)
-- The general condition (age) of the battery
The charging time is based on the aforementioned parameters and can be roughly calculated using the following formula (for a rough time estimation): Charging time (in hours) = the battery capacity (in Ah) x 1.2/charging current (in A)
Example: Lead-gel battery 20 Ah, empty
Charging time approx. 5 h. = 20 Ah x 1.2/5 A
d) Charger protective functions
Spark-resistant short circuit and reverse polarity protection
• These functions protect the charger from damage if the battery cables are accidentally swapped.
Overvoltage protection
• This function protects sensitive electronic components in the charger from damage caused by high-voltage spikes.
Limitation of charging current
• This function prevents overheating and damage caused by short or excessive loads.
Automatic overheating protection
•Overheating protection prevents damage to the charger due to abnormal ambient temperatures or component failure.
Please note that the in-built heat protection in the charger constantly monitors the operating temperature of the electronics. If the operating temperature exceeds the pre-set safety limit, the current is reduced in order to prevent overheating. This reduces the output current to avoid further temperature increases until the temperature has dropped sufficiently for safe, full performance.
13
10. Care and cleaning
Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may damage the housing or stop the product from functioning properly.
•Disconnect the product from the mains and disconnected any connected batteries before each cleaning procedure.
•Use a dry, lint-free cloth to clean the product.
11. Changing the fuse
• If the fuse in the device has burned out (there is no voltage at the charging output with a battery connected), send the charger to the technical customer service department or other specialist for repair or a fuse change. Never change the fuse yourself.
12. Disposal
