    SAFETY INFORMATION: DANGER! Avoid danger to life and limbs caused by improper use! CAUTION! Do not operate the appliance with a damaged cable, power cord or plug. Avoid danger to life and limbs caused by improper use! PROTECT YOURSELF FROM AN ELECTRIC SHOCK! When connecting the charging station, use a screwdriver and a spanner with an insulated handle! DANGER FROM ELECTRIC SHOCK!
  • Page 8 SAFETY INFORMATION: Do not leave small children unattended with the battery charger! • Children are too young to assess the possible dangers associated with electrical devices. Children should be supervised in order to ensure that they do not play with the device.
  • Page 9 SAFETY INFORMATION: DANGER OF CHEMICAL BURNS! Protect your eyes and skin against chemical burns caused by acid (sulphuric acid) upon contact with the battery! Wear: Acid-resistant glasses, clothing and gloves! If your eyes or skin come into contact with sulphuric acid, rinse the affected part of the body with plenty of clear running water and seek immediate medical assistance! •...
  • Page 10: Product Features

    PRODUCT FEATURES: This appliance has been designed for charging a variety of SLA batteries (sealed lead acid batteries), as mainly used in cars, motorbikes and several other vehicles. They may be of types e.g. WET (with liquid electrolyte), GEL (with mit gel-type electrolyte) or AGM (absorbed glass mat) batteries. A special design of the appliance (also named „ten-phase-charging strategy“) enables the recharging of the battery to almost 100 % of its original capacity.
  • Page 11: Operation

    PRODUCT FEATURES: Step 9: Analyse Tests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced. Step 10: Maintenance Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 12.8V (12V) and 25.6V (24V), the charger will start the Maintenance cycle until voltage reaches 13.6V (12V) and 27.2V (24V) and then discontinues the charge cycle.

    CONNECTION: • Before starting the charging or discharging procedure on a permanently installed battery in a vehicle, first disconnect the minus pole connecting cable (black) of the vehicle from the minus pole of the battery. The minus pole of the battery is usually connected to the car body. •...
  • Page 13: Memory Function / Reset

    MEMORY FUNCTION / RESET: After connection to mains, the charger automatically returns to the last charge mode used. If the charger stays on “STANDBY” press the mode key. SWITCHING BETWEEN MODES: NOTE: Long press 3sec. the MODE selection button at no battery connected status.
  • Page 14: Automatic Detection Of Battery

    AUTOMATIC DETECTION OF BATTERY: As soon as the battery charger has been connected to the mains, the charger recognizes the battery based on the following criteria: If the battery voltage is lower than 2.0 V or higher than 14 V, the battery is not suitable or defective. The error message appears and flashing on the display.
  • Page 15: Recover 12V Mode

    RECOVER 12V MODE (14.7V 26A): REACTIVATION OF DEEP-DISCHARGED 12 V BATTERIES USING PULSE CHARGING This mode is mainly suitable for charging 12 V lead-acid batteries with a capacity greater than 50 Ah. Long press 3 sec. the MODE selection button, if the measured voltage is between 2.0 V and 14 V the battery is identified as a 12V battery to activate RECOVER 12V mode Then if you do not take any further action, the electronic system will...
  • Page 16: Truck) Lead-Acid Battery Mode

    MODES (29V 13A / 29.4V 13A): This mode is suitable for charging 24 V lead-acid batteries with a capacity less than 25 Ah. Press the MODE selection button to select MODE After doing so, the corresponding LCD display lights up. Then if you do not take any further action, the electronic system will automatically start the charging process together with the LCD display will flash at (with a current of) 13A.
  • Page 17: Agm + 12V Mode

    AGM + 12V MODE (15V 26A): This mode is mainly suitable for charging 12V lead-acid batteries with a capacity greater than 18 Ah. It can be used to the maximum charge voltage 15V of the special AGM battery such as calcium battery; however battery manufacturers may recommend the maximum charge voltage for charging their batteries.
  • Page 18: Lithium + 16V (Racing) Mode

    LITHIUM + 16V [RACING] MODE (16V 19.5A): Long press 3sec. the MODE selection button, if the measured voltage is between 2 V and 12.8 V the battery is identified as a Lithium (16V 4-cells LiFePO4) to activate LITHIUM + 16V [RACING] mode. Then if you do not take any further action, the electronic system will automatically start the charging process together with the LCD display will flash at (with a current of) 19.5A.
  • Page 19: Special Functions

    SPECIAL FUNCTIONS: 0V battery charging. This feature is used for zero volt batteries; it uses a very small pulse current to sense the connection of the battery. This function is used in lithium batteries, as lithium battery pack has Protection Circuit Modules (PCM),the battery pack output is 0V when the PCM have actioned.
  • Page 20: Cleaning And Maintenance

    CLEANING AND MAINTENANCE: CAUTION: Disconnect from mains prior to carrying out any cleaning work. Danger of electrocution! Never immerse the charger in water as entering water can damage the charger. When necessary, clean charger with a soft, dry, lint-free cloth. Only when heavily soiled use a damp, well wrung-out cloth and mild, non-abrasive cleaning agent.
