SCA 2.4 Watt Solar Maintenance Charger Instruction Manual


Before using the SCA solar maintenance battery chargers ensure the instructions have been read and understood.

  • The SCA solar maintenance battery chargers are not intended for use by young children or infirm persons. Please keep away from pets.
  • SCA solar maintenance battery chargers are designed to charge most 12 volt battery types including: Lead-acid, Deep-cycle, Calcium, Gel and Absorbed Glass Matt (AGM)batteries.
  • Always wear the appropriate Personal Protective Equipment (PPE) when working near batteries. This includes gloves and eye protection.
  • For maintainable batteries it is advisable to read the operation manual before charging.
  • Ensure battery is being charged in a well-ventilated area. Explosive gases may escape from the battery during charging. Never charge a battery in a closed off space or in anarea without ventilation.
  • Never smoke, use an open flame or create sparks near a battery or charger whilst charging as gases may cause explosion. Please keep burning cigarettes, flames orother ignition sources away from the charging battery at all times.

  • If battery is still connected in the vehicle, ensure vehicles ignition is switched off before charging the battery.
  • Do not place the SCA solar maintenance battery charger where it is not able to get adequate ventilation. Do not place on fabric/leather/vinyl seats, on the battery orbalanced in the engine bay.
  • Never charge a frozen battery, non-rechargeable, lithium or dry cell battery.


  • For advice, contact the Poisons Information Centre in Australia (PH: 13 11 26) or the National Poisons Centre in New Zealand (PH: 0800 764 766)
  •  If battery acid makes contact with the skin or clothing, wash immediately with soap and water.
  • If battery acid makes contact with the eyes, hold eyelids apart and flush the eye continuously with fresh running water for at least 15 minutes or until the Poisons information centre advises you to stop.
  • If battery acid is swallowed, do not induce vomiting. Drink a glass of water and seek medical assistance.

Solar Maintenance Chargers are designed to maintain a charged battery (12V) NOT for charging a deeply discharged battery. Prior to charging the battery, check the electrolyte level. If the level is low, add demineralised water to the correct level, as indicated on the battery.Step 2.Voltage Check Prior to connecting the SCA solar maintenance charger, ensure that the battery voltage is adequate enough to receive charge. If the battery does not contain enough voltage the maintenance charger will not be able to provide adequate current to maintain your battery. Please Note: The SCA solar maintenance battery charger will not charge from zero volts.*For voltage requirements see Technical SpecificationsStep 3.Connect SCA solar maintenance charger to battery Connect the SCA solar maintenance charger to the battery, via the 12V battery clamps. DO NOT start the vehicle while the charger is connected to the battery with cigarette lighter or Battery Clamps. Electrical surges from the engine when starting and running may damage your charger.


The black lead & clamp indicates (-/Negative).The red lead & clamp indicates (+/Positive).Ensure that the correct polarity is connected to prevent a short circuit.This charger is not reverse polarity protected.Ensure the battery is in a safe location on a stable surface with adequate ventilationEnsure the correct Personal Protective Equipment is being worn I.e. Gloves and Eye WearConnect the suction caps to the SCA solar maintenance charger (where applicable) Attach to the windshield either inside or outside of the vehicle OR on a surface that is close to the batteryNote: SCA Solar Maintenance Charger is NOT waterproof, or water resistant, and must be in a well ventilated area Connect the 12V Battery Clamps to the SCA Solar Maintenance ChargerConnect the RED Battery Clamp to the Positive Terminal (+/Positive) on the battery Connect the BLACK Battery Clamp to the Negative Terminal (-/Negative) on the batteryWhen ready to disconnect Disconnect the BLACK lead (Battery Clamp) from the Negative Terminal (-/Negative) Disconnect the RED lead (Battery Clamp) from the Positive Terminal (+/Positive) Using a Voltmeter check the voltage of the battery before connecting it back in the  vehicle Ensure that the battery has been secured correctly

Step 4. Charging

Once connected,tinted windows or a dirty solar panel will affect the battery chargers ability to charge a battery . The battery charger will need to be placed in a location where there is sufficient sunlight and ventilation available to be able to trickle charge the battery, and (if required) cleaned with a soft cloth to ensure adequate charge. The charger is designed to top-up charge in a battery due to natural discharge. If your battery is fully discharged please use a suitable 240V AC Battery Charger.
