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. -
Page 12: Connection
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 15A): 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 7.5A / 29.4V 7.5A): 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) 7.5A. -
Page 17: Agm + 12V Mode
AGM + 12 MODE (15V 15A): 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: Smps 13.6V Mode
SMPS 13.6V MODE (13.6V 5A): This mode is adaptor, it can be used to as a 13.6V 5.0A DC power supply, and it can be used to float charging for 12V battery also. Long press 3sec. the MODE selection button at no battery connected status after doing so, the corresponding LCD display SMPS 13.6V lights up. -
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.
