This manual contains important safety and operation instructions for correct use of the battery charger. Read through the
manual and pay special attention to the markings and labels of the charger, battery and equipment connected to the
Failure to heed this warning may cause injury to persons and damage to Equipment.
Failure to observe this warning may result in damage to equipment and improper functioning of the Charger.
WARNING:
● The charger is designed for in-door use. Protect the charger from ingress of water.
● This charger is made to charge only properly sized lead acid batteries.
● Don't recharging non-rechargeable batteries.
● Charging other types of battery or under-sized lead acid batteries may cause fire or explosion.
● Install the charger in accordance with all local codes
● Do not use the charger if it has been dropped or damaged.
● Do not remove casing of the charger, there is no user-serviceable parts inside.
● Do not charge the battery on boats. Remove the battery and charge on shore.
● Never attempt to charge a frozen battery
● Never attempt to charge a damaged battery.
● Wear protective goggles and turn your face away when connecting or disconnecting the battery.
● Never place the charger on top of a battery.
● Never smoke, use an open flame, or create sparks near battery or charger during normal charging operation as
batteries may give out explosive gas.
● Do not charge batteries in an enclosure (box- in) due to possible explosion of entrapped explosive gas.
● Use of accessory not recommended may cause risk of fire, electric shock.
● Disconnect the mains supply before connecting or disconnecting the links to the battery.
● If the charger does not work properly or if it has been damaged, unplug its AC and DC connection.
CAUTIONS:
● Refer to battery manufacturer's specific recommended values for battery type settings and float voltage setting.
● Fix the charger to a solid support via three grooves at the flange of chassis, with three screws or nuts.
● Ensure all ventilation ports are not obstructed for efficient fan cooling, keep loose soft material or paper off at the vent
holes of the charger.
● During charging, the battery must be placed in a well ventilated area.
● If longer output charging cord is required, make sure the diameter is adequate for the current in given cable length.

  • Page 2: Control And Indicators

    INTRODUCTION Congratulations on purchasing our new Multi-Stage (IU0U) Switching Mode Smart Battery Charger. This software based MCU control 7 stage smart charger is designed with user friendly features and software plus hardware protection. It is a set, connect and forget charger that ensures complete recharge of your battery. Your battery can be connected indefinitely to the charger which will enter into energy conservation mode to prevent over charging and save electricity bills.
  • Page 3 Current can be selected to 20%, 40%, 60%, 80% and 100% of the max current. Details please see the label under the moveable door. (Default at 100%) Back Light ON/OFF switch (Only for SBC-9138/9238) Toggle ON/OFF the backlight by pushing the removable door, no need to open the door.

  • Page 6: Charging Profile

    D. Normal Multi-Stage (IUoU) Charging Operation The 7-stage IU0U charge algorithm ensures fast, complete and at the same time gentle charging of the lead acid battery. Charging Profile Stage 1. DESULPHATION charge - The pulse charging If the initial battery voltage is less than 9V, the charger will start Desulphation mode with pulse charge profile. The desulphation curve (DES) will display with slow flashing.
  • Page 7 Stage 7. STANDBY MODE - The constant voltage charging In this stage, the charging voltage at this mode will be 4% less than the Float voltage only for maintaining the capacity. The Standby curve (STA) will display with slow flashing. New Cycle Charge every 18 days Charger will start a new cycle charging of bulk to absorption to float every 18 days in either standby or float mode This new cycle of charging will refresh the battery to prevent separation of the electrolyte &...
