PREPARATION OF THE CHARGING

WARNING! ALWAYS DISCONNECT FROM THE MAINS BEFORE CONNECTING TO OR DISCONNECTING FROM THE BATTERY!

• Do not use on defective, neglected, worn or frozen batteries.
• Sealed batteries should only be charged with an automatic charger such as this, otherwise they may fail or explode due to overcharging. When charging conventional batteries, the plugs of the liquid filling openings must be removed to allow the gases produced to escape.
• The properties of different types of batteries vary considerably. They have different charging characteristics and require different care. This charger combines several charging methods, making it suitable for safe charging of many types. Batteries should not be allowed to run down completely, because if the terminal voltage falls below a certain level, chemical processes are triggered which will destroy the battery. when not in use store in a safe, freeze-proof place, periodic recharging is recommended. Check the instructions for your battery.
• Clean the battery terminals with a soft, slightly damp cloth, then wipe dry. In case of a conventional lead-acid battery, remove the caps from the cells and fill the cells with distilled water to the level specified by the manufacturer.
• Do not replace the sealing caps to allow gases generated during charging to escape. However, care-free batteries are sealed. Always follow the battery manufacturer’s instructions.
• Place the charger as far away from the battery as the wiring will allow. Gases or acid splashes can damage the charger. Never place the charger under/on/next to the battery! Do not place anything on top of the charger, do not cover it and ensure free air flow around it. WARNING! Danger of explosion! A spark or flame may cause toxic gases produced during charging to explode and must be prevented! Do not move the cables or switch on any electrical devices in the vicinity while charging! Ensure necessary and adequate ventilation during charging!

CONNECTING THE BATTERY AND CHARGER

• When connecting or removing the clips, the charger must be disconnected from the power supply by unplugging it from the wall socket. Never touch the clips to each other or to metal objects! Do not face the battery and move away from it before connecting the charger to the mains. It is usually easier to attach the open clip to the pole from above than to connect it from the side. Colour coding red: positive (+), black: negative (-)
• If the battery is in the vehicle***
• Remove the original battery terminals (the pole connected to the body first – usually the negative) so that the battery is not in electrical contact with the vehicle. This will protect the vehicle’s electronics and shorten the charging time. Make sure you have disconnected all equipment and removed the ignition key. A spark can cause toxic gases to explode during charging. It is therefore particularly dangerous to charge the battery while it is left in the vehicle. Do not move the cables, the bonnet, the doors or switch on any devices in the vehicle while charging, and do not start the engine. Beware of moving, rotating, sharp parts, belts, cables, fans! Place the charger as far away from the vehicle as the wiring will allow!
• Check the polarity of the battery contacts. Usually the positive (+/red) terminal is larger in diameter than the negative (-/black) terminal.
  1. Connect the clip-on connector cable to the charger cable.
  2. Connect the positive clip (+/red) to the positive terminal of the battery.
  3. Connect the negative clip (- / black) to the negative terminal of the battery.
  4. Plug the power cord into the mains and the charger is ready to use.
  5. The display shows if the battery is connected upside down or if the battery is faulty.
  6. Select the desired charging mode (battery type) by pressing the MODE button firmly. If you want to change the set mode while charging, disconnect the battery and reconnect it after a short time.
  7. The display shows the charging process. The symbol stops flashing when charging is complete. Depending on the battery type, capacity and conditions, this can take up to 25-35 hours. When charging is complete, disconnect the charger from the mains and remove the clips in reverse order. Remove the negative (-/black) clip first, then the positive (+/red) clip.
  8. If you do not remove the clips, the charger will maintain the maximum charge until the battery is used.
• The above procedure is recommended by the manufacturer of the device to increase safety. We do not permit charging the battery while it is left in the vehicle and connected to the vehicle’s electrical system in its original state. However, in accordance with the relevant standard (EN 60335-2-29), the following method should also be included in these instructions: first connect the charger to the pole not connected to the bodywork. The other pole should then be connected to the bodywork, away from the battery and the fuel system. Only then can the charger be connected to the mains. After charging, the charger must first be disconnected from the mains, then the pole connected to the bodywork must be removed first, followed by the other pole connected to the battery.
• If the battery is not in the vehicle
• The connection procedure is the same as described in detail above. Charging can be paused or interrupted at any time. Unplug the power cord from the wall and resume charging later. If the battery is not disconnected from the charger, charging will resume from the point where it was interrupted. This will also help in the event of a power cut. Otherwise, you will need to reset the desired mode using the MODE button.

THE CHARGING CYCLES

• This professional charger has several charging modes. It runs a diagnostic program once connected to the network. It checks the correct polarity of the connected battery, its possible sulphated state, its current condition and the functionality of the charger. If necessary, it automatically starts the desulphation process, which tries to increase the reduced capacity of the worn 12V lead-acid battery and regenerate the battery.
• It starts charging according to the manually selected battery type and its current state. The charging current is initially low, then ramps up as the voltage increases and decreases again as needed. The charging current is max.2A, this ensures gentle charging of all batteries, avoiding overheating, to achieve a longer battery life. When the battery reaches its maximum capacity, it switches to maintenance/maintenance charging with a low charging current.
• This completes the charge.
• If the battery is left connected to the charger for a long time, the self-discharge is compensated by the sustained charge. This method ensures that the battery can be used fully charged after a longer period of time.
• Charging time depends on the battery type, capacity, current state, charging mode and ambient temperature. Different types of batteries work differently. It is therefore important to follow the warnings of their manufacturers.
• If the battery is not fully charged after a long period of time, the charger will indicate that it has failed to charge after 60 hours. Some batteries may be old or worn out and cannot take the required amount of charge and therefore cannot be fully charged.
• In the event of a power failure – or if you accidentally unplug the charger while charging – charging will stop. When reconnected, the charging process will resume where it left off. This will only happen if you do not remove the battery from the charger. Therefore, do not remove the battery until the complete charging process has been completed.

PRECAUTIONS

• If the battery is already fully charged after the normal charge, the battery is fully charged. The charger will maintain the maximum charge. The charger can be connected to an unused battery for up to months. For this purpose, a screwable 10 mm bore ring connector is supplied with the clips. However, monitoring and checking the charge is recommended. It is not recommended to leave the device unattended for extended periods.
• If you work/stay near a lead-acid battery, always have someone nearby who can help. Wash off any acid that may come into contact with skin with plenty of soap and water. Take particular care not to get any corrosive liquid in the eyes. If it does get in the eyes, wash immediately with plenty of cold running water for at least 10 minutes and seek medical attention. Children must not be near and/or operate the appliance! Safety goggles, gloves and protective clothing must be worn. Do not touch your face or eyes when working with the battery. Attention! If the battery has spilled acid, wear protective gloves and clean the contaminated surface with a dry cloth!
• Beware of dropping a metal tool on the battery or the chips of the charger. This can cause a short circuit and/or spark and explosion. Do not wear metal objects (rings, bracelets, watches, necklaces…). A short-circuit with a high current can cause burns!
• Only charge the battery in a well-ventilated, dry place!
• Monitor the process, but not at close range! If the battery becomes very hot or if there is significant gas formation, disconnect it from the mains and continue charging later! The possibility of heating and gassing is reduced if the device switches to maintenance charging, thereby significantly reducing the charging current.

TROUBLESHOOTING

If the charger still does not switch to maintenance charging after 3 days after a full charge, a fault may have occurred.

Possible reasons:

• The battery is probably worn out and needs replacing.

• Batteries with high antimony content may behave differently, sometimes allowing the charger to charge for too long, which can lead to overcharging. Take care to avoid this!

• A sulphated, aged battery will take a long time to recharge, making it difficult to charge. A heavily worn battery cannot be fully charged. You should therefore always make sure that the charger is switched to maintenance mode after charging is complete before leaving it switched on and unattended. If the maintenance mode works, everything is OK. If the charger does not switch to maintenance mode after 3 days, the battery is probably no longer usable and needs to be replaced.
  If the device does not charge, the following situations may occur:

• No power; check the power and charging cable connectors.

• The fault indicator is lit because the polarity is reversed or the battery voltage is too low.

• The battery may be faulty.

• The tweezers are not in good contact or a blockage has occurred.

• It is possible that the charging mode is not selected for the battery.
