Solar Battery Charger

This product is a solar trickle charger for 12V batteries, which helps to manage battery drain in all
seasons. Can be used for cars or applications where a 12 Volt battery is used. Batteries naturally
drain power, especially in cold conditions. And if allowed to go flat, may never regain their full
power. Please ensure that you fully read the instructions before installing the product and retain
them for future reference.

IMPORTANT

In some makes of vehicle, the cigarette lighter may not operate when the ignition is turned off. In
such cases, you can connect directly onto the battery using the alligator battery clamps a1d cable
provided. Please note that the black lead indicates negative (-) and the red lead indicates positive
(+). Ensure you connect to the correct battery terminals, if in doubt check with your local garage.
Wrong connections may cause sparking or explosion.

ASSEMBLY/LOCATION

• Assemble the suction cups onto the charger.

• For optimal power, ensure the panel is directly facing the sunlight.

• The charger can now be attached to the inside or outside of the car windshield.

• Connect the main cable to either the cigarette lighter socket or directly to the battery.

• Alternatively you can wall mount using the keyhole slots on the rear of the charger.

OPERATION

• As long as there is sufficient sunlight available, the charger will produce an electrical current to
trickle charge your battery.

• An LED is located in the edge of the case; this will flash whenever the battery is receiving
charge.

• The charger will not damage or over-charge your battery. Similarly, a blocking diode ensures
that the charger cannot flatten your battery.

• The solar charger is a basic trickle charger and it is best for slowly charging and maintaining
battery charge. Please note that the charger is designed to top-up battery charge as a result of
natural drainage. It is not intended to recharge a battery that has fully discharged.

• Clean the solar battery maintainer monthly or more frequently to maintain peak efficiency.

• The charger can withstand splashing but is not fully waterproof and should not be submerged

or left outside during rainfall.

WARNING!

You must disconnect the charger from your cigarette lighter or battery when starting you engine or
driving. Electrical surges from the car engine when starting and running may damage your charger.

NOTE!

Some vehicles have tinted windows that will seriously affect the performance of your charger if it is
positioned behind them. For Optimum charging the unit should be placed outside the vehicle in direct
sunlight
